ANSMANN 9V Block Batteries [Pack of 2] 300mAh NiMH Precharged Rechargeable 9V E-Block Battery for Walkie Talkies, Speakers, Microphones, Multimeters, Clock Radios, Remote Control Cars, Toys

Worst stored discharge rate of any that I've tried which as I need them for a medical appliance is totally unacceptable, worst than useless as undependable.

expensive but top class in quality

Better than anything else on the market.

Great longevity in powerful 9v bedside /car emergency torches.

Great Batteries

brilliant batterys use these in my acoustic guitars and they last a long long time saves all the fiddling changing themtop marksGeoff

Good old trusty Ansmann. Nice feature is the long-term charge retention and the fact that, unlike more exotic high-capacity PP3 blocks, most existing chargers will likely be adequate for use with this formulation

Very 'green' these rechargeable batteries! Buy with confidence!
