KYMCO Battery Size Chart: Battery Part Numbers by Model

The right KYMCO battery is decided by the model, not the label on the old one: previous owners often fit whatever was on the shelf. This KYMCO battery size chart lists the factory battery for every model in our catalog, from the YTX5L-BS in the smallest Mongoose to the YTX20L-BS that cranks the big MXU and UXV machines. Match your model below and you get both the industry size code and the genuine KYMCO part number.

• Drawn onF11 Batteryon the People S 200 (2008); the code differs by model

Where the battery is drawn

Open a card to see the battery on that machine's factory diagram, with its callout number and every neighbouring part. The same part can sit under a different diagram code on another model, so use the chart above to find yours.

Reading the battery size code

The code (YTX12-BS, TTZ14S) is an industry standard, so any quality AGM battery in the same size works. The number approximates capacity (a YTX20L-BS holds roughly twice a YTX9-BS), the trailing letters describe terminals and case. Stay with the factory size: a smaller battery may physically fit an ATV's tray but will struggle to crank a 500 to 700 cc engine on a cold morning.

How to confirm fitment for your exact model

Model names repeat across years and regions, so the safest way to order the right battery is to confirm it on your model's own diagram:

1. Find your machine. Pick it on the All Models page, or decode your VIN with the VIN lookup to land on the exact model year and colour.
2. Open the diagram. The exploded views mirror KYMCO's factory fiche; the diagram cards on this page show which drawing the battery sits on.
3. Match the number, then order. Check that the number on the diagram matches the row in the chart, then follow it to the product page on kymcopartsstore.com, where the part is ordered.

If a part number has been superseded, the product page shows the replacement, so you always receive the current factory part.

Keeping a powersports battery alive

Most KYMCO batteries die from sitting, not from use. If the machine parks more than a couple of weeks, as ATVs and snow-season scooters often do, a smart maintainer pays for itself several times over. Check that the charging system holds 13.5 to 14.5 V at mid revs; a failing regulator-rectifier kills new batteries fast.
