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.

How do I know the polarity of my motorcycle battery?

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.

For your Harley-Davidson Softail 1450 Softail Deuce Injection we found 5 compatible AGM or EFB batteries.

📏 Battery size

The list contains batteries in different sizes or capacities (Ah). In many cases both variants fit, but it's worth checking your compartment dimensions and the Ah of your original battery before buying. Choose the one with the same dimensions as your current battery: a bigger one may not fit the compartment or the hold-down. If several match your size, the higher capacity gives more headroom for cold starts.

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.
