Unlike flooded rechargeable batteries, sealed rechargeable batteries do not contain a liquid that will spill out if the battery breaks. Instead, sealed rechargeable batteries hold only enough liquid to allow the electrolytes to flow. These types of batteries are also known as maintenance-free batteries.
What is a maintenance free battery?
Maintenance Free' is an unfortunate label for an automotive lead acid battery as all batteries require some maintenance (keeping the battery top clean, keeping attached cables tight and clean, keeping the battery charged or re-charged as soon as possible following a significant discharge etc.
Is a maintenance free battery AGM?
AGM batteries are a maintenance free alternative to traditional flooded lead-acid batteries. They are designed to provide powerful bursts of starting amps and run electronics for a longer period of time.
How do I know if my battery is maintenance free?
Non-maintenance-free batteries can also be checked by opening the fill caps on the top of the battery and looking inside . The fluid should be about 1/2- to 3/4-in. above the internal “plates,” or about 1/2- to one-inch from the top of the battery (just to the bottom edge of the fill hole).
Are batteries considered maintenance free?
Today's automobiles are typically equipped with maintenance-free batteries , but that doesn't mean they don't require a bit of tender loving care. Such batteries usually come with vent caps that are sealed, which means you no longer should check water levels — a requirement of some earlier batteries.
Can maintenance free car battery be recharged?
Charging car batteries? ... Modern, maintenance-free batteries have the advantage that it is no longer necessary to top them up with distilled water. In order for a car battery to perform reliably, a good charge level can be ensured by the use of car battery charger.
How long does a maintenance free battery last?
Sealed lead acid batteries can have a design life of anywhere from 3 – 5 years all the way up to 12+ years depending on the manufacturing process of the battery.
What happens if you charge an AGM battery with normal charger?
Overcharging an AGM battery can lead to reduced battery life . Many modern chargers allow you to select whether you're charging an AGM battery or a flooded cell option.
Is an AGM battery worth the extra money?
Definitely worth the price . The biggest perk is they hold their charge. You can charge it in the fall, come spring it's still 100% charged. I know mine has lasted quite a bit longer than my old lead batteries...that said, I never spent the money on lead then I now do on AGMS.
Do you need a special charger for an AGM battery?

What makes a battery low maintenance or maintenance free?
The construction of a low maintenance battery is similar to a conventional type, except the change in the grid material from lead-acid antimony alloy to lead-calcium . Since the performance characteristics are based on proven designs, the battery can be used on vehicles as an alternative to the traditional type.
What is the difference between a lead-acid battery and a maintenance free battery?
Traditional lead-acid battery electrolyte (water) is consumes, time need to add water; The so-called maintenance-free batteries, is in the whole service life don't need to check and add water (electrolyte).
Is it better to charge a battery at 2 amps or 10 amps?
It is best to slow charge the battery . Slow charging rates vary depending on the battery's type and capacity. However, when charging an automotive battery, 10 amps or less is considered a slow charge, while 20 amps or above is generally considered a fast charge.
