# Motorcycle Batteries > Find your motorcycle battery by make, model and year or YT/YTX/YTZ code. AGM, flooded and LiFePO4 lithium by Varta Powersports, Motobatt and Exide **Category:** [Start](https://baterias.com/gb/beginning) → [Batteries](https://baterias.com/gb/batteries) → [Starter Batteries](https://baterias.com/gb/starter-batteries) - **Canonical URL**: https://baterias.com/gb/motorcycle-batteries - **Language**: en-GB ## Description **Find the battery for your motorcycle** using the finder right below: select your vehicle step by step and see only 100% compatible batteries. Other quick paths: by [number plate](/gb/battery-finder-by-plate), by [part-number](/gb/part-number) from the manufacturer or by the **code printed** on your current battery (Varta E11, Tudor TC700, YTX12-BS, etc.). ## How to choose the right motorcycle battery Motorcycle batteries operate in tougher conditions than car batteries: constant frame vibration, high temperatures next to the engine, extreme cornering angles and tilt when parked. That's why most current bikes use **sealed AGM** — spill-proof, maintenance-free, vibration-tolerant and any-angle mounting. **Conventional flooded** (visible electrolyte) is still valid for classic bikes and old mopeds but needs level checks every 6 months. **LiFePO4 lithium** is the premium tier: a quarter of the AGM weight, 4-5x the cycle life, better cold cranking — but 3x the price and intolerant of flooded-engine starts. ### Typical capacities by displacement Displacement / type Typical capacity Indicative CCA Technology Moped 50 cc 4-7 Ah 40-65 A AGM / flooded Scooter 125 cc 7-12 Ah 90-150 A AGM Naked / trail 300-700 cc 10-14 Ah 120-210 A AGM Sport / custom 700-1,300 cc 12-18 Ah 180-300 A AGM or LiFePO4 Maxi-trail / Harley >1,300 cc 18-30 Ah 270-400 A AGM or LiFePO4 ### How to identify your current battery The code engraved on the top — **YTX12-BS**, **YTZ10S**, **YT12B-BS**, **YB14L-A2** — defines dimensions, polarity and capacity. It's the most reliable reference: with that code we find exact equivalents. ### Leading motorcycle battery brands - [Varta Powersports](/gb/batteries-varta) — AGM and AGM Active, German-made, factory-fitted by most OEMs. - [Motobatt Quadflex](/gb/batteries-motobatt) — AGM with 4 universal-polarity terminals. - [Exide Bike AGM Ready](/gb/batteries-exide) — pre-charged and factory-activated AGM. - Kronobat motorcycle — price/performance. ### Frequently asked questions ### **What if I fit a lower Ah battery?** The bike will struggle to crank in cold weather and parked loads (alarm, GPS) will drain it sooner. NEVER drop capacity below the original. ### **Can I switch to lithium if the bike came with AGM?** Yes, as long as the size fits. LiFePO4 is directly compatible with most modern regulators. Check with the manufacturer if your bike is older than 15 years. ### **Can sealed AGM be transported upside down?** Yes, sealed AGM doesn't spill at any angle. Only flooded with caps require an upright position. ### **Returns?** Free 14-day returns for mainland Spain and Portugal if the battery is sealed. ### **How long does shipping take?** Standard delivery **1 to 5 working days** to your country.
