I bought the battery as a replacement for my getting on in years screwdriver. I had to decide: New battery, new or screwdrivers, as the originals Bosch battery had no more power. With the original but I had problems from the beginning, he had always discharged completely after some time. And if you need the screwdriver, went nix. I had to recharge it before I could use the screwdriver. Since my ancient Lematec screwdriver was even better, who even after months still juice in its NiCd battery. Ultimately, I had decided for reasons of cost for these replica battery, and I'm thrilled! The battery can easily be in the original charger, charge, and he is a perfect fit in wrench. But now for the good: The battery lasts really long, and even if I did not use my screwdriver a few weeks, the battery still has power. He is better than the then supplied battery replacements, and I am pleased that is always ready to use my screwdriver Bosch now, when I need him. From me a clear KaufempfehlungIch !!!
