Sealed Lead Acid 12V 15Ah & 12V 12Ah Rechargeable Batteries

The 12V 12Ah battery and the 12V 15Ah battery are both the same physical size: 5.94 Long x 3.88 Wide x 4.00 High (to the top of the terminal). These rechargeable batteries are known as sealed lead acid or SLA batteries that will not leak acid.

Common applications for the 12V 12Ah battery include UPS backups, a plethora of mobility scooters such as Go Go scooters, Pride, Rascal and Shoprider. To kids two wheeled electric scooters and ride-on-toys from brands like Peg Perego for example. There are so many more applications; this SLA battery is like the workhorse of the sealed rechargeable battery world.

12 Volt 12Ah vs. 12 Volt 15Ah

As battery building techniques have advanced, manufactures have been able to produce higher amp capacities within the same size footprint. It is not uncommon to see 12 volt 14Ah and 12 volt 15Ah upgrades advertised as replacements for the original 12V 12Ah SLA battery size. The increased amp hour or ‘Ah number’ means the battery will be able to run longer before a recharge is required. A 15Ah battery provides 25% longer runtime between charges when compared to a 12Ah.

The 12 volt 12ah rechargeable battery has a universal footprint that will remain the same regardless the brand. There is no other sealed lead acid battery size with similar dimensions of roughly 6x4x4 (LxWxH). Some of the most popular brand part numbers include the UB12120 by Universal Power Group, PS-12120 by Power Sonic, the Werker battery WKA12-12F2 and a host of companies CB12-12.

When buying these types of 12 volt rechargeable batteries you should pay attention to the terminal size. There are two common types that look similar but are slightly different in width. The first is smaller and is known as F1 or P1 and is 3/16th of an inch wide. The other is known as F2 or P2 and is 1/4 of an inch wide. Don't worry if you end up buying a battery with the wrong terminal type, in most cases it is not the end of the world and it can be fixed by purchasing an adapter for few cents.
