Unlike traditional NiMH batteries, IMEDION can be stored for an extended period of time without substantial loss of power and are ready to use out-of-package. As the name suggests, the IMEDION batteries will be “ready when you are!”. A common problem that plagues rechargeable batteries is that they need to be recharged about once every one to three months even if they are not used. Maha tackled this issue by developing advanced electrode materials to reduce the rate of power loss during storage. As a result, the IMEDION batteries retain up to 85% of its charge even after one year of storage (at a room temperature of 20 deg C). The IMEDION batteries differ from the competition in that they boast a longer lifetime as well as increased power retention under warmer environments. The IMEDION batteries can be recharged hundreds of times and perform extraordinarily well at elevated temperatures. In addition, the IMEDIONS feature a low-impedance design and can deliver a high burst of current. IMEDION batteries are fully compatible with all Powerex chargers and are available in 2100mAh capacity for AA size and 800mAh for AAA.
