12 volt lead battery sizes

12v lead battery physical sizes.
The 12v batteries on this page have been listed by physical size to assist when finding an unknown model.

Batteries come in many shapes and sizes and we understand that it can be a little overwhelming when trying to work out the correct battery. This page is available for everyone, customers, dealers and wholesalers alike. Please use this page at your pleasure to find the correct size battery for your application.

How to use this page?
LxWxH is the first column and is how the sizes are organized. The smallest length will be first and at the top, following on from that would be width and finally height.

The Cell Type?
You may find that we do many of the sizes in various chemistries. AGM, GEL, WET and Leisure. Each one is different and cannot be mixed, however if you have, for example, a WET battery, you should be able to upgrade to AGM or GEL as a full replacement. You obviously may need a new charger.

AGM, this is a sealed type battery that needs no maintenance, except of course charging.
GEL, very similar to AGM, again sealed, can often be the choice in heavy duty application.
WET, this kind of battery needs to maintained, but a very effective cost to ampere choice.
Leisure, generally suitable for Starting a engine and deep cycle, a compromise of both, but not ideal for either
Starter, Batteries used to start engines, they are not for deep cycling
LIFEPO4, Lifepo4, a lithium battery with a BMS (battery management system), are sometimes used to directly replace Sealed lead and fool the charger into thinking that what they are

Terminals?
You will also find different 12v batteries have alternative terminals, hard to generalise on this page, but the pictures on the individual pages will help which you can access by clicking on the green button within each line.

We also have a page for 6v and 8v which can be found at the bottom of this page.
