Did you know that car batteries need to be maintained above 12.4V to ensure sulphation does not occur? The AA Solar Panel Car Battery Charger is ideal for vehicles that have occasional use, or are used for short journeys as it extends battery life by keeping the battery in a good state of charge. Modern vehicles have a small but constant battery drain - Modern vehicles can now have upwards of 30 body control modules (computers), plus alarm systems, immobilisers and lock monitoring.
Battery life is shortened if it is not kept charged - A 12V battery that is not correctly maintained above 12.4V can suffer from sulphation. Peace of mind - Vehicles that are used infrequently or do short trips are prime candidates for discharged batteries. The AA Solar Panel Car Battery Charger plugs directly into the EOBD plug socket inside your vehicle (standard on most cars, petrol from 2001 and diesel from 2004).

Selecting the right type of battery charger is essential to ensure longevity of your sealed lead acid (SLA) batteries. In order to choose the correct battery charger, you need to know the capacity, voltage and the type of SLA battery for which the charger is required.
Having determined the type of battery you have, the next step is to select the battery charger compatible with your battery. Apart from the voltage, you also need to know the amperage rating required to charge the battery. You need to choose a high quality battery charger that is fully compatible with your battery to protect it from incorrect charging.
Apart from purchasing a good quality battery charger, you must also ensure that it is compatible with the SLA battery.
The circuit given here is a current limited lead acid battery charger built around the famous variable voltage regulator IC LM 317. To setup the charging voltage, power ON  the charger and hook up a voltmeter across the output terminals and adjust R4 to make the voltmeter read 28V. I Have 36 volt 10 AH lithium battery, can I modif 24V lead acid battery charger circuit, to charger my 36 volt lithium battery?
Hello engr,in this your design.can i use it to charge two 12V,26AH lead acid battery connected in series?.if no,what is the implication? Two 12 volts batteries of similar type and conditions can be charged up to a maximum of 7 AH only. Hi joe Two 12 volts batteries of similar type and conditions can be charged up to a maximum of 7 AH only.
Hello engr,in this your design.can i use it to charge two 12V,26AH lead acid battery connected in series.if no,what will be the implication?
Hello would you be kind enough to publish a 48v 5 to 10 amp lead acid battery charger circuit ? This charger can be used for single 24 volt 7 AH battery or 2nos 12 volts 7AH batteries in series. Hi Tran you can charge 24volt 1.3AH battery (hope dry means dry fit lead acid gel cell) also. Thank you very much for the charger circuit, i would like to use this circuit for charging two lead acid (12v 150A X 2)battery, for inverter. Sorry, I can’t quite follow how the resistor R2 provides 700mA, can you explain how the calculation is done please?
I am looking to make an in-car charging system for an electric mobility scooter – it uses a 24v 10Ah battery. 1) can I substitute a 12v step-up DC-DC converter for the transformer and bridge rectifier section of your circuit to give me the DC input to the regulator, and what output voltage would the converter be required to supply? 2) what if any of the components of the regulated charger section would need to be changed to provide the correct output current and voltage? I’m a big fan of your circuits,and I would like to ask about the possibility of modifying this circuit so we can control charging current (like a pot.
Hi Gangadhar you can but ensure the output voltage is adjusted to 14.2 volts without load with pot R4.
My biggest source of support for this free website is when you use those or any of these links when you get anything, regardless of the country in which you live. Hint: I've been telling my normal friends who want a great camera to get the D3100 now while they still can, since it's the same thing as the D3200, for a close-out price. The D3100 has a new playback feature copied from the LEICA M9: when you look at the histogram, as you zoom and scroll around the image, the histogram shows only what's in your zoom window. The two biggest external improvements over the D3000 and D5000 are a dedicated advance-mode switch (Single, Continuous, Self-Timer or Quiet), and dedicated movie-start and live-view controls.
The D3100 becomes my first recommendation for a low-cost, high-performance DSLR to replace the Nikon D40. Nikon claims the D3100 autofocuses as you shoot movies, but it tracks poorly and spoils the audio in the process.
The D3100 has no AF motor of its own, so just like the D5000, D3000, D60, D40 and D40x, it only autofocuses with newer AF-S (or old professional AF-I) lenses. Canon's best cameras still only see in black-and-white, and Canon's newest 7D only sees in two colors, not full-color as have most Nikons since the F5. Nikon also shares that Flash Color Information Communication is supported with the built-in flash and all CLS-compatible flash units.
PC (Prontor-Compur) Sync Terminal for studio strobes: No, but Nikon will sell you a Sync Terminal Adapter AS-15 to add it, but heck, I use an old Nikon SB-30 flash on my cameras as a remote trigger for my studio strobes instead of a PC cord. White Balance: Auto, incandescent, fluorescent (7 types), direct sunlight, flash, cloudy, shade, preset manual. It's interesting to note that Nikon just can't keep up with the video resolution of Canon's DSLRs like the 7D and 5D Mark II. EN-EL14 Li-Ion battery, which is, at least as of October 2010, unique to the D3100 and the P7000. The great news about the charger is that Nikon finally got smart and gave it a folding plug, not another cord we need to carry.
Nikon says the Nikon D3100 is equipped with a Consumer Electronics Control (CEC) bus that enables remote control playback of images and movies recorded with the camera when the camera is connected to a high-definition TV. Nikon claims the Nikon D3100 is equipped with a new exposure compensation algorithm for greater flexibility and performance with NEF (RAW) processing.
The kit with 18-55mm VR sold for about $640 in 2010-2011, and was down to $547 the day before the D3200 was anounced. Forget the Quiet mode, which isn't that much quieter and is very slow to respond; the D3100 is super quiet in its regular modes. The Info screen rotates as you rotate the camera, but a firmware defect prevents the playback images from rotating as you rotate the camera.

Even though the focus screen is clear even if there is no battery in the D3100, if the lens isn't mounted correctly the focus screen goes almost black as a warning.
The charger now uses, at least for the USA version, an integral folding plug, saving us from having to carry a cord with us. At 14MP, its resolution is effectively the same as any 12MP camera, be it a DX D300s, FX D3 or D700. Here are two enlarged crops from images made at the same angle-of view and presented at the same print size.
This comparison was shot on a closed test range with synthetic reference vegetation and a controlled atmosphere. At ISO 3,200, image quality looks like it came from a cell phone: it's grainy and softer. A firmware defect causes the Auto ISO to rise to the same high ISO it would pick without flash.
The D3100 suffers from Nikon's chronic firmware defect of leaving Auto ISO active in the manual exposure mode, also requiring we switch off Auto ISO in the menus when shooting in manual mode. ADR works great, often filling shadows that otherwise would go black, or highlights that would have washed out. Simply turn Auto Distortion Control ON in the green Camera menu, and JPGs pop out with straight lines perfectly straight!
The S95 doesn't actually track focus, but due to its smaller sensor, the laws of physics give it a huge depth-of-field, so everything stays in focus, instead of having to hunt for it as does the D3100. I like the playback functions, the D3100 scrolls around the image very fast, and it also can scroll diagonally. As a consolation, the D3100's playback zoom zooms so far that we easily can see each and every image pixel greatly enlarged on the LCD. If you're looking at the RGB histogram, zoom-in and you'll see the histogram computed for only the region shown in the zoom. I'd get a D3100 instead of other bigger, heavier and more expensive cameras unless you have a very clear, stated reason that the D3100 won't work for you. The reason I prefer to shoot FX cameras is mostly because the viewfinders are much bigger and I like to shoot old manual-focus lenses.
For flash, I'd get an SB-400, since it will allow much faster shooting than with the little built-in flash.

On Camera FlashSo for On Camera Flash I don’t think you can go wrong with your camera manufacturer's own brand of product. Coloured Gels & GridsI use coloured gels quite a bit for creativity and also colour correction.
Studio Light Mount for hot shoe flashesI’ve got Bowens studio lights which I love if I’m doing a shoot where I don’t need to move about or travel light. These units all consume valuable electricity from the battery (up to 0.02 of an amp per hour).
Sulphation is the number one cause of battery failure, something not covered under warranty as it is not a manufacturing defect. The solar charger will trickle charge and maintain a 12V vehicle battery while the vehicle is parked by converting light energy during daylight hours into 12 volts DC.
There is built in discharge protection as well as reverse polarity protection and the Solar Charger will not overcharge your battery. On receipt by us of the returned product(s) we will give you a full refund or arrange to send you the correct product(s), whichever you would prefer. We will refund the full price of the products as soon as possible following your notice of cancellation, no later than within 14 days. SLA battery chargers vary a great deal in terms of the type of batteries they can charge and battery charging duration. You need to first find out the type of sealed lead acid battery you will be charging before selecting a particular battery charger. You should choose a battery charger depending on the current required to completely charge the SLA battery. You have to determine the required amperage and voltage of the battery charger to safely charge the battery.

As per your requirement of 26 AH a power pack capable of maximum current limit of 7 amps (9 amps preferred) is required. Pls I need your urgent assistance in responding to these questions to enable me modify this circuit to do something else. I tried to insert a second BC547 as suggested (base of 2nd BC547 to base of 1st and emitter to the other emitter and collector to a led and a 2.7K resistor to C1 positive) to indicate full charge with no luck whatsoever! Pls can u send me the circuit diagram containing the charging indicator(green and red).pls send it to my email. It's big, but a bit grainy; you can see each pixel, unlike the high-resolution screens of the D90 and above.
This makes it trivial to check highlights more precisely than ever before on any Nikon: just zoom in and look around! The D3000 took way too long to process and record images made with ADR (Adaptive Dynamic Range), had awful high-ISO performance, and the D3000 locked-out image review controls until after you hit the PLAY button! The rear dial can select the AF point, but if you want to go between the auto-area select mode, single point mode or multipoint tracking modes, you have to stop and set it using the LCD. Just bring the right passive plug adapter, plug it in, and you're good to go, without any cords! The AF marks are little more than tiny dots, and only one red LED dot lights for a moment when first activated.
It doesn't do this if there is no memory card, even though by default it won't shoot either.
If each image was printed in its entirety at this magnification, presuming your computer has a standard 100 DPI monitor, each print would be 46 x 31" (117 x 78cm).
For these shots, I used a tripod and the atmosphere was set to no heat shimmer and no wind, with normal humidity. Changing lenses to the kit lens wouldn't have looked any worse on the D3100, and resampling or JPG quality didn't change anything, either. In other words, with Auto ISO and flash, you'll usually be shooting at ISO 3,200, or whatever you've set for the maximum Auto ISO ISO! If you need even more power (not likely), the SB-600 is ideal; the bigger flashes are too big and complex as far as I'm concerned.
If you wish to make a printout for personal use, you are granted one-time permission only if you PayPal me $5.00 per printout or part thereof. If you require further details regarding the transaction data, please contact the supplier directly. You will probably be using this as a sole source of light for your On Camera Flash photos and you need reliability and quality as well as TTL capabilities. I always used to recommend and use Pocket Wizards as that was the industry standard and it used to be the only reliable triggers you could get.

They will help your flash recycle quicker, meaning that you’ll be less likely to miss a shot while your flash waits to get its power back. I’ve had a few different types over the years and I always recommend getting metal ones of these. I’ve got a collection of different light modifiers that i’ve invested in for my Bownes Lights, so there’s softboxes, reflectors, grids, snoots, beauty dishes etc. This means that over the course of a week or two with no or little vehicle use the battery can become discharged. The unit is maintenance free and will protect the battery against the discharge process that occurs naturally within a lead acid battery.
The 'THINFILM' technology allows a wider spectrum of natural light to be absorbed, meaning the unit can still generate electricity under cloudy winter conditions.

It is important to select the right battery charger to ensure optimal charging, efficiency, and protection of your SLA battery. You should determine whether you have a Gel Cell or AGM (absorbed glass mat) battery since Gel batteries require a specific type of charger. You need to determine the maximum charge rate of the sealed lead acid battery, which is usually printed on the front or side of the battery. A battery charger with a high amperage rating charges the battery more quickly as compared to a battery charger with low amperage. All you need to do is to connect the battery charger connector to the battery with the right polarity.
You need to consult the battery charger manual to determine how to know when charging is completed. In addition, a low quality or defective charger may also result in abnormal charging of the battery. The quiet helps us photograph without disturbing others, and the low vibration ensures sharper hand-held shots. Instead of big etchings for each AF area, there are subtle, fine lines and tiny LED dots that light, only for a moment, to highlight the AF point selections.
At higher ISOs, noise reduction blurs the images to keep the D3100's noise about the same as FX cameras. Those problems were unique to the D3000 and fixed in the D3100, so good riddance to the D3000. Heck, I can see artifacts better on the D3100's LCD than I see them on my 30" Apple monitor, mostly because I never dare enlarge them beyond 100% as the D3100 makes so easy. I’ve been teaching photographers all about flash since 2008 and the market place has really changed since then. However my friends over at Rouge sent me a pack of their colour correction and coloured gels and I love using them as they come in a handy little pack that keeps them all organised. This technology also enables the solar panel to handle the intense heat of the summer sun with little power loss due to the rising temperature.
If we receive an order after 2pm for a next day delivery this order will be dispatched the following working day. If you are not concerned with the time it takes to charge the SLA battery, a battery charger with a lower amperage rating will suffice.
You may need to read your battery manufacturer’s instructions to determine the correct polarity of your battery.
A number of battery chargers include a special sensor that automatically shuts the battery charger once the charging is complete. When you invest in a good quality battery charger, you ensure maximum protection and longevity of your battery device.
In order to calculate the time required to charge the battery, you need to divide the power rating of the SLA battery with that of the charger and then add extra 10% for the time required to top off the battery. A faulty SLA battery or charger can result in overheating or battery failure that can be dangerous.
You don't even need the Quiet mode, which is as easy as flipping a big switch on top; the D3100 is supremely quiet in all its modes.
This makes it much easier to compose than with many other inexpensive DSLRs, like the nasty AF point display in the Canon 7D.
A thousand-dollar lens on a five-thousand-dollar camera, and all this still looks the same as the D3100 and a regular lens. I’ve tried a load of different equipment over the years to see what works and what doesn’t. I also looked at a load of different types of grids for my flashes and I ended up choosing the Rouge grid spot as it’s very small, built well and very versatile.
Please note that 'next working day' orders placed before 2pm on Friday afternoon will be delivered the following Monday (except bank holidays).
The important thing to consider when buying battery charger is that the current rating of the charger should be higher than that required by the SLA battery. But generally, a plus sign or a red marking on the battery indicates positive polarity while a black marking or a negative sign indicates a negative polarity.
You need to get both your SLA battery and the battery charger, checked by a qualified personnel to know the cause of the problem. It’s a constantly evolving process and if I were to write this in a years time, it may very well be totally different. As it’s built in (well clipped in) to the flashes and I don’t have to worry about wires, batteries etc causing a weak link and the flashes not firing. I got a cheap one many years ago, but it’s probably worth getting a named brand so it lasts. Orders placed after 2:00pm on Friday afternoons, or on Saturday or Sunday will be dispatched on the following Monday and delivered on Tuesday (except bank holidays). Make sure that you connect the battery charger connector with the right polarity or else, it may damage your battery. Diode D1 prevents the reverse flow of current from the battery when charger is switched OFF or when mains power is not available. I’ve always spent good money on my equipment and it’s always lasted me for many many years. I can’t see the point in spending a load of money on an expensive umbrella when a cheaper one with do the same job. So what i’m recommending here is stuff that if looked after, should last you for a long time as well.
The cheaper ones that I’ve just mentioned and a double fold very portable one, that’s great for putting in my bag and not worrying about. I’ve always found you end up buying the expensive stuff anyway in the end and just waste your money on the cheap stuff in the first place.I’ve also tried to provide links to the cheapest places to buy the equipment on Amazon to make things easier for you.
