PowerEx PreCharged Rechargeable 9V Battery - 8.4V, 300mAh, Ultra Low Self-Discharge

Retains up to 85% of charge after one year in storage - Never find your rechargeable 9V batteries low on charge when you need to use them!PowerEx's new "PowerEx PreCharged" (formerly "Imedion") line of NiMH rechargeable 9V batteries feature a unique extremely low discharge design. Unlike ordinary NiMH rechargeables, which will lose a significant amount of their charge within just weeks, the unique chemistry of the PowerEx PreCharged batteries allows them to retain up to 85% of their charge after a whole year of storage. Rated at a true 8.4V @ 300mAh, these batteries are ideal for medical or other devices which don't require or cannot utilize the higher 9.6V voltage of PowerEx's standard 9V battery. With their unique low self-discharge design, PowerEx PreCharged batteries will actually provide longer battery life than regular NiMH rechargeable batteries of a much higher capacity rating in any device that is used intermittently over a period of time. Made in Taiwan. Unique new chemistry
