This battery with 2700 mAh each, I bought because I have no desire to permanently dispose of batteries. Instead, I invite on - time after time; We are talking here not even to cover the costs, but to the environment. Even with the initial charging maintain these batteries as long as normal battery depletion (amps) is usually significantly lower.
For me, a good alternative to conventional batteries, the charger to a Eimalaufwendung and does not cost much. Sometimes there is the charger in the package to low. In the long run it benefits the environment and the wallet.
