ANSMANN 9V Block Batteries [Pack of 1] 300mAh NiMH Precharged Rechargeable 9V E-Block Battery for Walkie Talkies, Speakers, Microphones, Multimeters, Clock Radios, Remote Control Cars, Toys

However, it's the same as my old ones which have performed extremely well for years and years.I've mainly used them in my guitar, which has a pre-amp, with no ill effects whatsoever.They're virtually half price so I'm guessing they may be old stock.

You can tell by the weight that these are the real deal unlike some of those un-branded ones. Works well in my headphone amp. About as good as you can get in 9v NiMh

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

Just what I have come to expect from Ansmann. Top quality rechargeable.

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.

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

Excellent would buy again and recommend
