I have some important tips on how to take care of your car battery, the sign of low power battery and damaged battery, What causing the battery to fail, When to change the battery (battery life span), precaution on battery, how to replace car battery aided with video, battery problems and any other important tips that you must read to make sure your car always in a good condition due to proper maintenance of car battery.
Car batteries suffer if heavily discharged, damaging the cells as well as failing to start the car.
If the battery has removable vents (maintenance-free batteries may be sealed, and low-maintenance batteries may not be easy to open) check the electrolyte level.
A battery has a bunch of lead walls in it and they produce chemical electricity by mixing and moving acid around inside. Dropping batteries is bad, do not do that, you could break open the case and cause acid to leak out.
If you pop open your hood and see a bunch of blue, yellow, or just weird looking powder on your batter post. The basic voltage, current rating and size of battery will be given in the dealer’s catalogues, and these must of course be right for the make and model of car. Maintenance-free batteries will use lead-calcium for both grids, and this is nowadays a widely sold type of battery. Having selected a make and type, look for the date of manufacture, or ask the dealer to check it, if it’s not shown. If the car battery is too weak to provide a sufficient charge to the starter, the solenoid switch will not function correctly.

The lead-acid battery is a reliable battery system that operates within a large temperature range, and its charge-discharge process is practically reversible.
In the lead-acid battery, the active material within the positive electrode consists of lead dioxide, while the negative active material is a metallic lead.
The major component in the lead-acid battery is highly purified lead, from which alloys are made so that the lead can be made into a grid-like material, as lead in its pure form is unable to maintain this shape. New applications for battery power in fields such as storage, emergency power, and electric vehicles, as well as the more traditional uses in automobiles, boats and planes, warrants the continued dominant use of lead-acid batteries. It has several disadvantages as well, including a low cycle life, which is about 50-100 cycles for the average lead-acid battery. So, if the charge warning light comes on, or if the battery seems very sluggish on starting, get the system checked as soon as possible. Top up to cover the plates with distilled or deionised water – de-frost water from the ’fridge is ok provided it’s absolutely clean. Before removing either battery lead make sure any radio and security codes are noted as given in the handbook, and the engine must be stopped.
But when your car bounces around a lot these lead walls loosen up, brake off, and can cause your battery to die quickly, or not operate and leave you stranded.
Modern car batteries have a life expectancy of around five to seven years, but it’s pretty much impossible to predict when the end is getting near. The battery case will also have a decal stating its expected life, such as 60 or 84 months.
The starter is a small but powerful electric motor which depends on the car’s battery for its energy.
If you found out your battery is weak, go to nearest workshop and replace with the new one.

The covers are heat sealed to prevent electrolyte contamination, and there is a liquid-gas separator area, which returns liquid to the reservoir, thus providing the battery with a longer life. With all the alternative sources of energy being explored and implemented; we are seeing a rising trend in demand of Lead acid batteries. With maintenance free or low-maintenance batteries, topping up should only be necessary every year or so: have the charging rate checked if much water is being lost. Remove the negative lead (Black – ) first, then the positive (Red + ), and just lightly scrape the battery posts and the inside of the terminals. To reduce vibration of your battery make sure that your battery is secury straped down, usually cars have some sort of bracket or tie down to hold it in place. That means acid has leaked from your battery and is eating away at your battery post and cables.
So, the options are to soldier on until it fails, or change it at say five years – and the latter is probably the best option. These factors will be reflected in the price of car battery, as generally the higher capacity and longer warranties go with the more expensive brands. If a calcium battery is more than a year old, or for other types say six months, look for a newer one, or at least check that it has been recharged within the last three months. Once the key has been turned in the ignition, a circuit between the battery and the starter is completed through a solenoid switch. However, these batteries have a high cost and you will need to spend quite some money to replace them (average life of commercially available deep cycle batteries is 1.5-2 years) when they die out on you. Coat the faces with petroleum jelly and re-attach, tightening firmly but not over-straining the fixings. By running the car the alternator generates electricity and runs it back to the battery and charges it.
If you feel your battery may be bad, just take it to your nearest auto shop and have them test it, they usually don’t charge you for it, or charge very little.
In most cases they’ll be worth paying for – particularly in the case of a diesel where cold-start current demand will be higher than for the same sized petrol engine.
This is where we come in with our guide on how to rebuild a battery from your dead battery. Letting your battery die by leaving the key on or the lights and then having to jump start it all the time is bad for your battery, you shouldn’t put your battery in such extreme conditions.
If it’s bad they are very easy to change the battery, just take off the two battery cables, and then remove the holding bracket. A three or four years’ warranty indicates a greater degree of confidence on the part of the manufacturer. But a simple procedure called a load test can be performed to determine if the battery is ready to be replaced. When taking off the battery leads, make sure to take the negative (black) lead off first then take off the positive (red). Be sure not to inhale any of it because it’s not good for you and also it can eat through your clothes after you wash them. A serviceman will attach a voltmeter to the battery’s terminals while the car is running.
Alright, so how do you build a battery from an existing dead battery and more importantly why does the battery die?


If you clean it and the acid comes back, then I recommend replacing your battery and buying battery protectors which sit on your battery post to help keep acid from forming.
A switch on the voltmeter will then change the power load from the alternator to the battery alone.
Acid can build up and go into your battery cables and cause resistance in your electrical systems causing your car to act funny. Sometimes a weak alternator will be the culprit, but other times the test will reveal a weak battery not capable of holding a charge. This results in a decrease in battery’s capacity and consequently failure.You can recover the oxides (covered later in the article) from the positive plates that have fallen victim to the anodic corrosion and use it to make paste for the new plates. So; we will be using the negative plates to make a new cell with the paste that comes from oxides. This means that you’ll be building a 3 cell battery from 6 cell battery.Advertisement Now to get to the job’ remove the positive plates and have them placed in a metal container, which can take some beating. Use a hammer or anything that is hard that can transfer impact to turn these plates into powder. Once you have crushed the plates, remove small pieces of lead and grid from the mixture by sieving the contents.
Mix this powder with sulfuric acid and water to form a paste which will be placed into the plate’s grid structure and cured. Mix the fiberglass and glass fibers that have been recovered from the separators to strengthen the paste. Once the paste has been applied you will need to cure the plates, which is usually done at 30 degree Celsius in high humidity for about 48 hours. At home, just put them in a pot that is filled with water into the oven and keep an eye on the water level. First off, cut the top off the battery and leave about 5 mm of plastic around the terminals.
Now you need to cut the interconnection between the cells and remove the cells from the case.Now you need to perform the process of forming in which, active materials are formed on the new plates.
The idea is to pass electric current and then reverse the direction and continue the same procedure for about say 30 times.
If you continue indefinitely you’ll destroy the plate.Let’s make some electrolyte, shall we?
Alternatively, you can buy a sulphuric acid solution with 1250 sp gravity from a battery shop to use as a battery electrolyte. Now all that is left is placing the plates back into the case, sealing the top and filling it with electrolyte. If you still decide to do it, make sure to work very safe as the lead-acid is very dangerous.
