Tenergy High-Capacity NiMH Rechargeable Batteries
Both the Premium and Centura lines of Tenergy NiMH rechargeables are available in AA, AAA, C, D and 9 Volt sizes. The Premium is their high-capacity line which range from 1000 to 10000 mAh respectively. The Centura batteries range from 800-8000 mAh from AAA to D, with 200 milliamp hours available in the 9 Volt. These LSD versions can take 1000 recharge cycles and may be stored for up to 6 months while retaining 90 percent of their charge. After one year that lowers to 85%, comparable to the other batteries on our list. These rechargeables also lasted exponentially longer than standard alkaline batteries in various devices, most notably cameras, R/C toys and other electronics that require large amounts of power. However, when stacked up to other rechargeables on our list, they performed well in most cases, with only a 20-30 minute difference in power life between these and the other brands. Not a wide margin, but noticeable nonetheless.
