Does the SOK battery have low-temperature protection?
Yes. The BMS inside the battery will prevent charging below 0°C in order to protect the cells. It will allow the battery to discharge in freezing temperatures. If you need to charge the battery in freezing temperatures then we recommend the heated versions.

Can I store these SOK batteries in the cold?
The lowest safe storage temperature is -6°C. For any temperatures below this, you should bring them inside or add a heating pad of some sort. If a heating pad runs out of power and the battery falls below -6°C, damage may occur.

Do the SOK batteries fit into a standard "group size" battery box?
No they are likely too big to fit into standard boxes. Many people put them in tool boxes or any enclosed unit that protects them from the elements. The metal case units are not fully waterproof while the plastic case (marine version) are 100% waterproof.

Can I use any charger on the SOK batteries?
The batteries have a 7 year manufacturer warranty. If you are having issues with the battery we are here to help. In the rare case of a warranty claim we will ship you a new battery and deal with the claim with SOK. The 7-year warranty covers anything that fails or doesn't stand up to the manufacturers' specs, and includes both the cells inside and the BMS.
