Car Battery

One thing you tend to forget about until it fails is the car’s battery, a part without which the vehicle won’t run anymore. Woefully, most vehicle owners forget that making a quality pick is important in the long-term as it ensures a greater lifespan, and they just pick out the first model that is compatible with their vehicle. There are a lot of aspects you must take into consideration when making the replacement, not blindly guiding yourself after the requirements specified by the vehicle manufacturer, but rather taking power demand into consideration as well – this is only in case you added certain options that weren’t there when you bought it, like parking sensors or a new sound system.

Grouped by their size, the technology featured, reserve capacity, CCA, and other factors, automotive accumulators are an inevitable purchase for a vehicle owner. What is important for you to do is to research and find a battery that doesn’t only meet the power demand of the vehicle and makes for an appropriate fit, but one that delivers a lengthy service life and is backed by a generous warranty, thus avoiding another failed attempt and ending up having to replace it again only 1 year later.

Care Tips

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.

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.
