We test the battery's state of charge, start capacity, determine the overall condition of the battery and identify problems such as cell short circuit.
While we are testing the battery we will test the alternator's charging capacity, loaded and unloaded and provide full print outs of both battery and alternator condition.
Should your battery need to be replaced we can supply and fit a high quality Bosch replacement battery offering a 3 or 4-year warranty.
The reason that lead acid batteries go bad is because every battery charger on the market, except for Tesla Chargers, chronically under chargers the battery.
Many self-proclaimed experts will tell you that you can just increase the current (amperage) and boil the lead acid batteries a bit to get it back into shape. And, with the conventional circuits that other companies use, they don’t know how to bring the lead acid batteries to the proper voltages for full desulfation without boiling them to death.
Tesla Chargers circuits are made by John Bedini, the world’s recognized master of lead acid battery charging and rejuvenation. As the voltage goes up, it comes to a peak and when the final layers of sulfation are removed in the range a bit over 15 volts, you see the voltage drop. Tesla Chargers products are based on decades of lab tests by John Bedini and most specifically in the early 2000’s.
One of the big reasons that battery prices have gone up is because the cost of lead has gone up considerably in the past decade. Another reason that the price of automotive batteries has gone up is because batteries today are better than car batteries in the past.

Question: Why do car batteries go dead in the winter?It’s almost like my car battery knows when it’s the absolute worst time to go dead on me. The Real Car Battery Killer: Temperature ExtremesLead acid batteries are designed to work in fairly large range of temperatures, but performance suffers in both cold and hot environments. If rechargeable lithium ion batteries can blow up, should we really be using them everywhere?
Charge away: lithium batteries don't have 'memory' problemsBack in the day, we all dutifully let our phones and seven-kilogram laptops go totally flat before recharging to avoid the dreaded battery 'memory' problem a€” where batteries held less and less charge over time if you recharged them before they were fully flat. The memory problem was caused by a build-up of crystals on the electrodes in the battery, leaving less room for the chemical reactions to take place there during charging. These are the key areas in which the Coalition, Labor, and the Greens hold different policies. This service may include material from Agence France-Presse (AFP), APTN, Reuters, AAP, CNN and the BBC World Service which is copyright and cannot be reproduced. Well, today we finally made it down to town after being stuck up the mountain for five days because of the snow. If you do not drive your car or battery powered hover craft or battery powered personal helicopter at least every few days then you may find, as we do, that the battery goes flat.
So, you may ask, if you have a cheap solar trickle charger to stop a battery from going flat why did the battery go flat.
To keep the car battery from going flat all I would have had to do was use the supplied suction cups, stick the panel to the windshield with said suction cups and attach the crocodile clips (supplied) direct to the battery or use the cigarette lighter option (also supplied) and simply push it in.
Living here in Minnesota, I can relate to dead car batteries, fuel lines freezing in sub-zero weather and ice storms where you are lucky to be able to open your car door. A couple years ago when my battery seemed a little sluggish and was slow to turn the engine over a friend borrowed me a solar trickle charger and I put it on the dash and plugged it in. Chest Freezer To Fridge Conversion-The Most Energy Efficient Fridge EverWhich Solar BackPack To Buy? How Long Does it Take to Build a Chicken Coop?So last week we finally got around to building the new chicken run.
A New BeginningIt’s been a while (um years!) since A Self Sufficient Life was updated and a lot has changed for the Dirty Boots Gang. Enjoyable Emergency Food Survival – Grow Your OwnIf you want to feed your family yourself, why not simply grow your own? Emergency Survival Food Supply 275 Meal PackI came across the Emergency Survival Food Supply 275 Meal Pack the other day and it got me to thinking about all manner of things. During very cold periods of weather breakdown organisation such as the RAC and the AA can replace up to 1200 batteries a day.

If we identify any other issues with your car's charging system we will advise you of the associated repair costs. However, that is a scam because removing the sulfation on the lead plates is a VOLTAGE event and NOT a current event.
Because the sulfation presents an impedance and that causes the voltage to rise like back pressure against a gas.
It was a manual teaching farmers a century ago how tokeep their lead acid batteries indefinitely good. The most up to date line that we have are better than ever and these products have saved literally hundreds to thousands of tons of batteries from the scrap yard since 2006 when Tesla Chargers first launched. If you haven’t replaced your battery in a few years, you might be in for a surprise when you go to get a new one. Automotive batteries contain lead, so the higher cost of lead means a more expensive battery. The companies that produce and sell automotive batteries have improved the design and the quality of materials used. More and more battery brands and resellers are adding a battery warranty to the cost of the battery. Is there a reason that car batteries go dead in the winter, or are they really just as likely to go dead at any time, and I’m just really unlucky?Answer:While it’s true that winter is a fairly common time for car batteries to die, some sources actually suggest that more batteries die in the summer than in the winter. According to Industrial Battery Products, lead acid battery capacity drops about 20 percent from normal in freezing weather, down to about 50 percent of normal when temperatures sink to about -22 degrees Fahrenheit.In the same way that extreme cold reduces the capacity of a lead acid battery, high temperatures actually increase the capacity. The battery consists of a positive electrode (green) and a negative electrode (red), with a layer (yellow) separating them. Full charge puts stress on the electrode material.Check the manufacture date when you buy them a€” they start losing capacity to hold charge from day one. It was a real issue for nickel-based batteries, but with their different chemistry lithium ion batteries only show a very minor effect. Depending on the swing of the seats, both Malcolm Turnbull and Bill Shorten could face serious post-election challenges. Luckily we had plenty of food and were not too short on the vino either although it was getting dangerously low! It took me ages to shovel snow from under the car and repeatedly rock it back and forth, back and forth so that I could jump start it. The battery was so dead the poor cold thing did not even have a spark of life in her bless her. One is used to charge a battery we have in the house that is connected to a DC pump that runs our water and I installed it weeks ago.
We now sue it to keep our water pump battery topped up and it did do the job in the winter of topping up the car battery. But the voltage can still sit there even if the full capacity of the lead acid batteries isn’t actually there. The chemistry involved in discharging a battery is 100% reversible; this can give a theoretical INFINITE number of cycles to lead acid batteries. This has been known for a century, but the manufacturers of lead acid batteries of course have neglected to tell you this.
When the final layer of sulfation is removed and dissolved back into solution, that electrolyte becomes more conductive, impedance drops, and the voltage goes down. Most automotive batteries, depending on the type of battery and the brand, cost well over a hundred dollars. So you may be dealing with a case of confirmation bias, but that doesn’t mean you’re totally off in left field. In fact, a lead acid battery can exhibit about a 12 percent increase in capacity at 122 degrees Fahrenheit versus 77 degrees Fahrenheit.Of course, that increase in capacity doesn’t come without its own downside. And aren't they bad for the environment?Rechargeable batteries already power our phones, laptops and toothbrushes.
When in use, lithium-ions (Li+, blue) travel from the negative electrode (anode) to the positive (cathode).
In fact, letting them run completely flat would actually destroy them, so the batteries in your devices have a circuit that shuts them down before they reach that point. After heaving and pushing and digging for what seemed like the whole morning I finally got it in the right position. So, get the battery out of the car with my freezing hands and trudge back up the hill it is. I had to drill holes in the stone that makes up our rustic house, insert rawl plugs, drill a tidy hole through the wooden window frame so the cables (which are really long) could run inside to the battery and all manner of fiddly things. So, the next spring I found a nice 12v 5 watt panel on sale and ended up using it for other purposes around the house all year too.

If you haven’t bought a battery for a vehicle for a few years, you may wonder why they are so expensive. The science behind lead acid battery technology actually shows how both hot and cold weather can be unkind of the life and operation of a car battery.Even though hot weather is a real battery killer, for a number of reasons, cold weather is also hard on car batteries. During charging, the process is reversed and lithium ions are transferred back to the anode.
Electric cars and solar storage systems have entire control systems devoted to avoiding death by discharge for individual batteries.So recharge your devices whenever you like a€” but try to give them a full charge (let the battery go into the red) every now and then to recalibrate your battery level reading.
On with the  electric battery charger  (yes, it is run by solar panels, it gets convoluted doesn’t it?) we have in the house and after 30 mins or so it was restored to a low powered but self sufficient enough life to work for my second jump start attempt. The second reason is because many people forget whether or not they bought a battery with a warranty. This is why it’s a great idea to have your battery checked out before you head off on a summer road trip, while it’s an equally good idea to have some regular battery maintenance performed in the fall before it has the chance to leave you stranded in a snowstorm.
Under normal circumstances, your battery will offer no complaints, as the ability to deliver a lot of amperage over a short period of time is one of the things that ancient lead acid battery technology is terrific at.However, a battery that is already getting long in the tooth can have a lot of trouble in the winter. At number three in the periodic table, it's the lightest metal, which really helps it store more energy for the same weight and volume.Smart phones, tablets and new laptops all use lithium ion batteries.
Most of the time, the consumer has lost the receipt or forgotten about the warranty by the time they have a problem with their battery. And even if a battery’s capacity isn’t reduced by age, temperatures that are at or below freezing can even knock the capacity of a brand new battery so low that it can’t handle the demands of the starter motor.When you look at a battery’s vital statistics, cold cranking amps (CCA) is the number that refers to how much amperage the battery can put put out cold. Keep your receipts, and if you have a problem with your battery, look at the expiration date for the warranty. If the number is large, that means it is equipped to handle higher demands than a battery with a lower number, which in turn means that it will perform better in cold weather, when capacity is diminished.In some cases, especially in very cold weather, starters motor amperage demands can be even higher than normal, which can compound the problem. Those reactions allow positively charged ions to move from one electrode to the other inside the battery, and negative electrons to move through the wires in the circuit, producing a current.But with rechargeable batteries, plugging your charger into an external power source forces these chemical reactions to happen in reverse.
But they've also been behind fires in Boeings, Tesla electric cars and laptops in the past 10 years.
The issue is that motor oil gets thicker when the weather is cold, especially if you’re dealing with a single weight oil that doesn’t have different viscosity ratings for cold and hot weather.
The positive ions (Li+ in lithium ion batteries) recombine with electrons at the surface of the negative electrode, ready to start all over again when the battery is connected to a circuit. When the oil gets thick, the engine can be more difficult to turn over, which in turn can cause the starter motor to draw more amperage.Winter driving typically also puts a higher strain on your battery, due to the demands of accessories like headlights and windshield wipers that tend to get used more often when the days are shorter and the weather is more likely to be inclement. Lead-acid (car) batteries, cans of petrol and all other energy dense materials can explode too.But the push to make portable batteries lightweight adds an extra risk to lithium ion batteries.
Unless you have a high performance alternator, you may find your charging system struggles to keep up.
Components like the separators that keep the battery's positive and negative electrodes apart are built thin to keep battery weight down, but if they get pierced a short circuit can form between the electrodes and quickly heat things up. And since the battery may already be suffering from reduced capacity due to cold temperatures, this can hasten the demise of an old battery.The Reason Car Batteries Die in the SummerIn the same way that cold temperatures are hard on car batteries, hot temperatures can also have a negative effect. A spark from the short can set off a fire, and a build-up in pressure as the heat goes up can literally make the battery explode.Lithium batteries don't age gracefullyFrom the moment they're made, lithium ion batteries start losing their ability to store charge and generate a voltage over time. It's called ageing, and it happens whether they're being used or not, so check the date of manufacture when you buy a lithium ion battery.The ageing is caused by chemical changes at the electrodes.
The positive electrode isn't a solid lump a€” it's made of microscopic particles of a lithium-based material.
Over time those particles coalesce together forming bigger lumps, so there's less surface area for the lithium-releasing reaction when the battery is being used (discharging).And recharging doesn't send 100 per cent of the lithium ions back to the negative electrode a€” some ions always get permanently stuck to the positive electrode. Similarly, overcharging a battery can significantly shorten its life, damage it internally, and even cause it to explode.Keeping a Car Battery Alive in the Winter and SummerAny time your car battery is operated outside the optimum temperature range, the fact is that there is a greater chance it will fail, whether it’s freezing cold or boiling hot outside.
The biggest ticket item is the cobalt and nickel in the positive electrode (cathode) in some batteries, and the solvents used in making the electrodes. According to Interstate Battery, a weak battery will start to freeze at 32 degrees Fahrenheit, while a fully charged battery won’t freeze until about -76 degrees Fahrenheit. Of course, it’s also a great idea to have your battery load tested, the electrolyte checked, and the connections checked for any signs of corrosion before the winter chill comes around.In the same way, you can help your battery last longer in the summer with a little preventative maintenance. Since one of the biggest culprits of battery failure is heat, which causes electrolyte evaporation, it never hurts to keep an eye on your electrolyte throughout the warmer months.
If the electrolyte starts to drop, then you can top it off before the problem becomes any more serious.
