Super long running time with high capacity: AA (2600mAh), AAA (900mAh), C (5000 mAh) and D (10000 mAh)
Very long life time means thousands of dollars in savings by eliminating the need to buy hundreds of throw away Alkaline batteries. A similar throw away battery package like this would cost you $15 $20, but they can be used only once.
Exact replacement for standard AA/AAA/C/D size batteries and NiCd rechargeable batteries
Convenient operation due to that advantage that NiMH batteries have no memory effect. Can be charged anytime
Can be rapidly charged with smart chargers and universal chargers
