If you own a car, chances are you’ve heard of maintenance-free car batteries, and have been told they’re the only way to go. But what actually makes them so special? And are they actually right for you? Let’s find out.
What are maintenance-free car batteries?
Before we go any further, let’s make sure we’re all on the same page regarding what we’re talking about. When you search for “maintenance-free car batteries” on Amazon, you’ll get a lot of results for sealed batteries, which are often advertised as maintenance-free. But some of these batteries are still not truly maintenance-free. What’s the difference?
Sealed batteries have a hard case surrounding the plates, making them more durable than standard car batteries. But the hard case does not mean they are completely maintenance-free. To make them easier to install, the case is often punctured when you put them in the car, leaving them susceptible to corrosion from the water in the battery compartment. So even if the batteries are advertised as maintenance-free, it’s still a good idea to check the water level periodically and to clean up any corrosion if you do find some.
The true maintenance-free batteries are sold with a soft case. They are sealed and have no vent caps, so there’s no need to check the water or remove corrosion if it does start to form.
