The battery is what keeps you warm, so it is worth getting right. This collection brings together every BERTSCHAT® power option in one place: replaceable battery packs from 2,200 to 4,000 mAh, high-capacity powerbanks, and 12V systems built for jackets and vests. Whether you want a charged spare for a long day outside or more capacity for a larger heating surface, you will find the right power to match your product here.
Power for every heated product
Different products draw different amounts of energy, so we build our battery packs in a range of capacities. Compact packs suit smaller heating surfaces such as heated gloves and heated socks, while larger heating areas need more capacity. Matching the battery to the product is the key to steady, all-day warmth.
The smallest packs are light and flexible, which makes them ideal for undergloves and precision tasks. Mid-range packs handle everyday use, and the highest-capacity packs give you extended heating duration on colder days. For garments with a large heating surface, our powerbanks and 12V systems deliver the sustained output that heated jackets and heated vests require.
Every BERTSCHAT battery is replaceable, so when a set reaches the end of its life you simply order a new one instead of replacing the whole product. Fresh cells each season keep performance consistent. Pair your battery with the correct lead from our cables and chargers collection to keep everything charged and ready.
How to choose the right battery pack
- Capacity (mAh): Higher capacity means longer heating. A 2,200 mAh pack is light and compact, 3,000 mAh covers everyday use, and 3,800 to 4,000 mAh gives the longest runtime for cold conditions.
- Product match: Gloves, socks and insoles work with compact packs. Heated jackets and vests draw more power and pair with a powerbank or a 12V system.
- Connection type: Check whether your product uses USB or USB-C, so the battery and cable fit correctly.
- A charged spare: A second set keeps you warm through long days outdoors, with no wait for a recharge.
- Charging and care: Recharge your batteries regularly, even out of season, to keep the cells healthy. Our manuals explain the details for each product.
