Are all car batteries maintenance free?

“Maintenance-free” is an unfortunate label for a lead-acid car battery, since all batteries require some maintenance (keeping the top of the battery clean, keeping the cables connected very tight and clean, keeping the battery charged or recharged as soon as possible after a significant discharge, etc. Almost all lead-acid batteries, regardless of whether they are classic wet batteries (SLI) or modern AGM batteries, now require no maintenance. This means there is no need to refill with distilled water. Anyway, this should not be done by amateurs, but by your workshop.

However, a little care extends battery life, and a regular charge level check helps detect a weak battery before a deep discharge occurs. You can read about battery technologies and which ones are right for your vehicle in the article on the different types of batteries. There are two types of batteries that do not require maintenance. The first type uses acid in the form of a gel (gel), while the second type uses fiberglass mats (AGM, absorbent glass mat).

Both batteries produce water and oxygen on the positive plate and hydrogen on the negative plate to regulate water levels on their own. Here's a brief introduction to both batteries. How often you need to water your batteries will largely depend on how much you use them. For example, if you have a golf cart that you only use on weekends, you might not need water more than once a month.

Cars that have batteries that require no maintenance and that are used a lot may need water more often. To make this very easy, some batteries have an indicator that lights up green when the water level is good and darkens when it needs to be refilled. While you can buy a battery that is labeled as maintenance free, the battery may have removable covers to check water levels, although most owners of these batteries spend the entire life of the battery without having to add water. It has a double ventilation system, or you can say that it contains a quick cooling separator that prevents batteries from overheating and also provides an optimal temperature.

You can also ask them for home service, and they use environmentally friendly recycling methods, making them one of the best car service providers in the country. Find out which batteries require maintenance and how best to complete this task to get the most out of battery life. Maintenance-free batteries use lead-calcium terminals, reducing battery overheating. All of this helps to devote minimal effort, time and money to maintaining the battery and makes it an economical option.

Some batteries need occasional maintenance by filling the battery water to ensure that the electrolyte solution mixes properly. Traditional batteries have liquid inside them, which can start to boil if overcharged and melt the battery and cause an accident. Now that you know the operation, manufacturing and benefits of maintenance-free batteries, you can turn to Car Fit Experts to invest in a maintenance-free battery for your car. A maintenance-free battery starts up easily even in cold weather thanks to its high reserve and cold start capacity, so you don't have to switch to public transport or make countless attempts to turn on the battery while you wait for it to warm up.

There is a risk of water spilling during recharging, which can cause corrosion, and since there is no need to add water to the battery that does not require maintenance, the risk of corrosion is reduced. Glass Mat absorbent batteries are designed for high demands, as they are versatile and have high performance. The recombination oxygen cycle and the sealed upper part (with only a small hole as a vent) ensure minimal water loss and reduce the rate of self-discharge, increasing the durability of batteries. Maintenance-free batteries can be an excellent alternative to traditional batteries, since they do not require constant recharging.
