This guide explains the different types of motorcycle batteries, how to identify them, and the proper procedures for filling, installing, and charging them for maximum performance and lifespan.
There are four main types of motorcycle batteries:
6N
, 12N
(Conventional) or YB
, CB
(Yumicron).YTX
, GTX
, ETX
, CTX
.CT
, YT
, YTZ
, etc.Battery capacity is measured in Ampere-hours (Ah). For example, a YTX9BS
or 12N9-3B
battery has a capacity of 9Ah, which theoretically provides 9 amps for one hour or 1 amp for nine hours.
Note: Real-world performance may vary, especially with modern ignition systems requiring stable voltage.
No filling required—gel batteries are pre-sealed and ready to use.
After charging, install the battery and apply petroleum jelly to the terminals to prevent corrosion.
