IMPORTANT!!!!! \u003c\/b\u003eThese are immensely powerful batteries, and extreme care should be taken using them. Only use with brand name, quality chargers. 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. \u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eUse at your own risk.
