Motorcycle batteries are compact, but the choice is just as precise as for a car: a few millimetres or a reversed terminal and it will not fit the compartment. Each model shows its standard reference, capacity, cranking current and dimensions. Covers scooters, naked and sports bikes, tourers, off-road bikes, quads and jet-skis. ## Start from the reference code Most motorcycle batteries carry a widely used designation such as YTX9-BS, YB12A-A or YTZ10S. The letters indicate the construction (for example, sealed factory-activated or supplied with an acid pack) and the suffix often points to terminal position and vent. Matching that code is the fastest route, but confirm **dimensions**, **polarity** and **Ah** anyway, because some equivalents differ slightly. ## Technologies for two wheels - **Conventional flooded**: the traditional choice for older bikes; it needs electrolyte level checks and an upright position. - **AGM (maintenance-free)**: sealed, vibration-resistant and the usual fitment on modern motorcycles. Some come pre-filled and ready to install, others with a separate acid pack to activate before use. - **Gel**: very robust against vibration and deep discharge, popular for enduro and quads. - **Lithium**: a fraction of the weight with strong cranking. Read our section on [lithium motorcycle batteries](https://bateriasonline.es/en/lithium-motorcycle-batteries) before switching. ## Keeping a motorcycle battery healthy Bikes are often parked for weeks, and alarms or trackers drain a small battery quickly. Connect a smart maintainer during long breaks and avoid charging at high current: a sensible rule is about one tenth of the capacity in amps. If the bike has been unused, check resting voltage first; a sealed 12 V battery below roughly 12.4 V needs charging. Brands such as [MOTOBATT](https://bateriasonline.es/en/motobatt-batteries) and [EXIDE](https://bateriasonline.es/en/exide-batteries) offer AGM and conventional ranges for most models. All starting categories are grouped under [starter batteries](https://bateriasonline.es/en/starter-batteries). ## Frequently asked questions ### Can I install the battery on its side? Sealed AGM, gel and lithium units can usually be mounted in several positions. Flooded batteries must stay upright to avoid acid leaks. ### What if my new battery comes with a separate acid pack? Fill each cell with the supplied electrolyte, let it settle as the instructions say, then give it an initial charge before fitting it. ## Choose by brand The same motorcycle batteries, filtered by manufacturer.
