received quick, cheap, but it is far (very far away ...) for keeping the original battery! rescue, it's been the case. but it is better to buy a 2nd battery of the brand, or (for the same price) 4 batteries like this one? 4 extra batteries, probably will last longer than a single additional brand. ok, but it makes a recharge 4 batteries, to transport .... so that difficult choices to make!
