# Snowmobile Batteries > Sealed AGM batteries for Polaris RMK, Ski-Doo Summit, Yamaha Sidewinder, Arctic Cat. High CCA for -40 °C cranking. Motobatt and Varta Powersports. **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/batteries-for-snowmobiles - **Language**: en-GB ## Description **Find the battery for your snowmobile** 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 snowmobile battery Snowmobiles crank 600-1,000 cc 2-stroke turbo engines at -25 to -40 °C. The battery must deliver cold CCA and then survive 6 idle months without losing too much charge. **Sealed AGM** with low self-discharge is the only viable option. ### Typical capacities Displacement Capacity CCA Technology Entry-level 600 cc 10-14 Ah 150-220 A AGM Sport 800 cc 14-18 Ah 200-280 A AGM Turbo 1,000+ cc 18-30 Ah 270-400 A AGM ### Off-season storage Before storing for the off-season: charge to 100%, disconnect the negative or connect a 12 V maintainer. Otherwise the battery sulphates in 4-5 idle months. ### Leading brands - [Motobatt Quadflex](/gb/batteries-motobatt) - [Varta Powersports AGM](/gb/batteries-varta) - [Exide Bike AGM Ready](/gb/batteries-exide) ### Compatibility and how to choose correctly Before buying, check the **minimum cold CCA**, **polarity** and dimensions for your Polaris, Ski-Doo, Yamaha or Arctic Cat snowmobile. Many models share a YTX format with big motorcycles, but it's worth confirming. Use the [comparison tool](/gb/comparator) to compare CCA, capacity and price before deciding. ## Frequently asked questions about snowmobile batteries ### **Why does a snowmobile need a different battery from a road motorcycle?** Because it must crank with very viscous oil at temperatures down to -40 °C in real use, requiring a **much higher CCA** than an equivalent motorcycle, on top of tolerating constant vibration on icy trails. ### **How do I stop it sulphating during summer storage?** Charge it to 100% before storing and disconnect the negative terminal, or better still, connect it to a 12V maintainer during the idle months. Without this, self-discharge sulphates it within a few months. ### **What CCA do I need to crank my snowmobile at -30 °C?** It depends on displacement: entry-level 600 cc models usually manage with 150-220 A, while 1,000+ cc turbo engines need 270-400 A to overcome oil viscosity in extreme cold. ### **Can I use a road motorcycle battery in my snowmobile?** Only if the format, minimum capacity, CCA and polarity match; many snowmobiles share a YTX format with big motorcycles, but it's worth confirming before buying.
