Note: Ensure batteries are fully charged to reach full capacity. Failure to do so may lead to long term cell issues.

Usage & Charging

!!!!! IMPORTANT!!!!! These are immensely powerful cells, and extreme care should be taken using them. Only use with brand name, quality chargers (like LiitoKala, Nitecore, XTAR) and equipment! Unfortunately, we cannot replace batteries that are damaged by non-compliant chargers or equipment. There are so many chargers on the market, we cannot possibly keep track of which ones will work with these batteries. You will have to contact the charger manufacturer to ensure it can charge these batteries without damaging them. Please ensure you only use these (or any other Lithium Ion) batteries with proper Lithium-Ion chargers and equipment. Lithium-Ion batteries can easily be damaged by charging them with too high current or exceeding the maximum rated current discharge.

Use at your own risk. We do NOT accept any responsibly for damage, injury or death caused by improper use of these batteries!

Do not overcharge! Ensure the charger voltage does not exceed the batteries stated full charge voltage.
Do not over-discharge! Ensure the equipment you use do not draw more current than the batteries “Maximum Continuous Discharge Current”.
Do not leave batteries discharged for a long period! Leaving Li-Ion batteries in a discharged state can incur irreversible damage – creating a loss in capacity and a loss in cycles.
