What type of battery does my motorcycle need?

Motorcycles can use GEL, AGM, or conventional batteries. GEL batteries are ideal for occasional use. AGM batteries are the best option for heavy use or high-power motorcycles. Always check the polarity before installation.

Polarity indicates which side has the positive (+) terminal. This is critical for motorcycles because some models have the positive terminal on the left and others on the right. Check the label on your current battery or the manufacturer's manual.

Can I install my motorcycle battery myself?

Yes. First disconnect the negative (−) wire and then the positive (+) wire. When installing the new one, connect the positive (+) wire first and then the negative (−) wire. Always respect the correct polarity.

Before you buy: check the JIS code on your battery

On motorcycles, the definitive identifier is the JIS (Japanese Industrial Standard) code printed on the original battery — for example YT12B-BS, YTX9-BS or YB12AL-A2. It identifies the model 100%: dimensions, capacity, polarity and terminal type.

Make sure the JIS code of the battery you are buying matches the one on your current battery
How to find the JIS code on your battery: it is printed on the manufacturer's label, usually on the top or front face of the battery, next to the voltage and capacity. It typically starts with Y (Yuasa) followed by letters and numbers: YT, YTX, YTZ, YB, YT-BS, etc. Some brands use parallel equivalents (FT, GT, BT, EB) — all follow the JIS standard. If the code of the battery you are buying matches yours (same letters and numbers before the «-BS» / «-A2»), it is the correct battery. If it differs even by a single digit, the dimensions or capacity do not match and it will NOT fit.

If you have any questions, just ask us and we'll be glad to advise you with no obligation.

AGM / EFB batteries

AGM or EFB technology batteries: more charge cycles, faster recovery and a longer life than a conventional battery.
