Every since I tested the first AA low self-discharge NiMH rechargeable battery, I've been waiting for someone to produce one in the 9V (PP3) size. It seems like everyone is producing the AA size, and some manufacturers are also making the smaller AAA, but no one has taken the trouble to make a 9V battery. Until now...
So, I was quite happy when I received an e-mail one day from Tenergy, asking if I'd like to review their new Centura line of line of low self-discharge AA, AAA, C, D, and 9V batteries. So far I've tested the AA and AAA sizes (included in my low self-discharge battery comparison), and the 9V size described here.
