12 Volt Lead Acid Motorcycle Battery Specs and Sizes

Conventional battery

12 Volt lead acid motorcycle battery specs…

Lead acid batteries (also known as conventional batteries) usually come with the acid in a separate pack and are filled through the stoppers in the top of the battery (6 stoppers in the top of a 12 volt battery, usually yellow in colour).
These type of battery have upper and lower level marks on the front and need to be checked and have the electrolyte level topped up with DISTLLED WATER occasionally.
Lead acid batteries usually start with the code CB or 12N (e.g. CB14L-A2 and 12N24-3).

The 1st letter of the battery code is a manufacturers letter and can be different depending on the battery manufacturer (so YB9-B, CB9-B, DB9-B, GB9-B, EB9-B etc are all the same battery).
Maintenance free batteries normally have black case and a plastic strip pressed into the top.

Please note – The power outputs stated on this page will vary depending on the make and quality of the battery!
