Tip: There is the possibility for the battery to still have some “juice” in it. To keep safe during the operation, we recommend that you wear proper protection gloves.
Phase 1:
- Make sure all the accessories and lights are off. Otherwise, the battery might arc when you work with it.
- Remove the negative cable of the battery first, and then proceed with the positive terminal.
- Clean the terminals with a mixture of water and baking soda to neutralize battery acid. Make sure that you wear a mask and eye protection for the airborne corrosion to not enter your mouth, nose, or eyes.
Phase 2:
- Make sure the charger is off.
- Hook the positive cable of the charger to the positive cable of the power cell.
- Hook the negative cable of the charger to the negative cable of the power cell.
- Set the charger to the slowest charge rate.
- Turn it on.
How Long Does It Take?
The answer depends on how severely discharged the battery is to begin with. If the voltage is below 11.85V and the charger you use puts out a 5-amp charge rate, it will take approximately 12 hours to perform a full charge on a 400-500 CCA model. With a 10-amp charge rate, it would take half the time to charge the same type of battery, 6 hours to be precise.
With models that boast more cold cranking amps and a lower open circuit voltage, the charging process take considerably more time.
By simply learning how to keep your vehicle accumulator up and running at its peak performance, you can avoid the dreadful situation where you have to go to an expensive service and replace it or pay a tow charge as you cannot start the vehicle and get to the destination yourself.
Seeing how check-ups are seasonal and they only take a few minutes, it would be a shame not to take up the habit of upkeep as there are only benefits to reap from doing so.
- Keep the cables clean: Using a post cleaner, make sure that you regularly clean the top of the auto battery and the cables so that you remove any corrosion. If it is rated as being corrosion resistant, it doesn’t mean that you are in the clear completely as this unwanted phenomenon could still occur. Thus, you should still occasionally check and see if you have any buildup to clean off.
- Park the automobile in a garage during winter: A little protection goes a long way when the weather turns bad, and when it comes to the protection of your automotive accumulator during winter, your best course of action is to park the vehicle in a garage. This way, the thoroughly insulated construction will keep it warm even in the coldest of days. However, avoid heated garages at all costs as the warmth promotes rusting.
- Check the water level for non-maintenance-free models: If the product you opted for is a wet-cell model that is rated to require maintenance, to keep it up and running perfectly for as long as possible, you should check the water level once every 2-3 months. In case the water level is low, pour distilled water into the cell with the help of a funnel. Just make sure you don’t accidentally overfill, and you are done with this upkeep task.
- Clean the terminals periodically: Preferably once every 6 months, you should take a wire brush and use it to clean the terminals. Dip the brush into a distilled water and baking soda mix that you prepare, and scrub it until it shines. Afterward, carefully remove the dry acid build-up that you swept from it, and you are done.
- Grease it up: Just like low temperatures, high temperatures play a major role in affecting lifespan. To prevent rust and corrosion from appearing as a result of high-temperature damage, you should coat it with grease that is specially designed to withstand high heat.
- Don’t skip regular vehicle service: Last and most important of all, take the vehicle to its regular tune-up. Once every 3 months or after 3000 miles since the last check-up has passed, take the vehicle to a professional shop or to a mechanic, and have regular servicing performed on it. If the vehicle is kept in perfect condition, it helps prolong the lifespan of the accumulator as well.
As batteries come in various sizes, it can get quite confusing to pick the right one for your car. However, this is a crucial step towards purchasing the right automotive battery as
if you don’t ensure a proper fit, it won’t provide sufficient power to the vehicle.
Another issue you will be confronted with if the battery isn’t the right fit is that the terminals won’t be in the right place and you won’t be able to reach them with the cables. What you should do is guide yourself after the instructions in the owner manual of the vehicle, or better yet, check out the fit guide we have provided you with.

Frequently Asked Questions
?Does it lose charge if I don’t drive the automobile all that often?
Accumulator death is an occurrence that can take place if you don’t drive the vehicle often. Basically, it is as if you would store it on a shelf and left it there, no charge being provided to it. While leaving the vehicle parked for a month without giving it a key won’t lead to the complete depletion of the accumulator, leaving it this way for more than half a year will lead its untimely death. Thus, the answer to this question is yes, it does lose charge if you don’t drive the vehicle.
?What are the effects of hot and cold climates on it?
Hot summer days, as well as incredibly cold winter nights, have a negative effect on the vehicle’s accumulator. When the temperature is abnormally high, fluid can evaporate, causing damage to its internal structure, the lead plates can corrode and deteriorate, and the charging system component could even malfunction, overcharging the system and terminating it completely. When temperatures are too low, its capacity drops considerably, which leads to it being unable to start the vehicle.
?What are the main aspects to take into consideration when making a purchase?
There are quite a few elements to take into consideration in addition to it being compatible with your vehicle. These elements include for it to boast a good reserve capacity that ensures it will run even when the vehicle is off when needed, ample cold-cranking amps that indicate low temperatures won’t affect it, a long service life rating which guarantees quite a lengthy journey alongside it, and a maintenance-free design which takes all the hassle off of your hands as you won’t have to add water or do any similar task to upkeep it.
