Frequently Asked Questions about 12V SLA Batteries

What is a 12 Volt Sealed Lead Acid Battery typically used for?

Our 12V SLA batteries are trusted for use in APC UPS systems, emergency lighting, exit signs, mobility scooters, wheelchairs, alarm and security systems, and much more. Whether you're replacing a backup battery or powering essential equipment, you'll find the right battery with the right fit.

What charger should I use for my 12V SLA battery?

Some applications will charge the 12V SLA battery automatically, like alarm or backup systems. You shouldn't need to take the battery out and put it on a charger.

If you do need a charger for your application, generally you will want a charger that is ~10% of the capacity rating of the battery (at a 20hr rate).

For example, if you wanted to charge a 12 volt, 20 Ah battery, you would select a 12 volt charger with about 2 amp charging output (20 x 0.10 = 2)).

What is the life of a 12 volt SLA battery?

The overall longevity of your battery will depend on a number of factors, including the application it's installed in, operating temperature, and the charging method. Most SLA batteries last between 300-500 cycles (recharges).

What SLA battery should I buy for my application?

We recommend starting with the voltage and dimensions. Most SLA batteries can be matched with that information. Then, you should check the terminal size and type. This is important if the battery uses spade (sometimes called blade) terminals, as these come in two sizes: F1 and F2.

How do I know which 12 volt rechargeable battery I need?

Finding the correct 12 volt rechargeable battery depends on matching the size, voltage, and capacity required by your device or equipment. You can check your old 12 volt battery for its model number, dimensions, or amp-hour rating, or look in the manufacturer’s manual for the recommended specifications. Battery Mart carries a large selection of SLA batteries in many sizes and capacities, and our customer service team is always ready to help you choose the best match for your application.
