KINGTIANLE 18V 5.0Ah Li-ion Replacement for Bosch GBA BAT609 BAT609G BAT619 BAT621 BAT620 Cordless Drill Power Tool Extended Capacity with LED Indicator

had 1 battery peter out within a year... just after return window<figures> and the second one lasted 18 months. the spot welds on the jumpers come loose and either have to tack them back in place or wedge something in them to keep contact

The moment I loaded the first battery onto the Bosch charger and the green light did not start flashing I knew it could only mean one of two things:1. The battery had arrived fully charged (very unlikely) or,2. The battery did not work.I tried the second battery and got the same result.Both batteries did have some charge, according to the power LEDs, so I tried them in a power tool. They snapped into place securely, but provided no power. I then switched to a genuine Bosch battery and all worked first time, every time.These batteries physically install correctly, but do not connect electrically.Worthless.

Good batteries, fits perfectly for my bosh screwdriver. Looks 99% same as original(body shape). Looks like real 5 Ah, because last more two times more than my original 2 Ah battery. Really happy with this purchase, worth any penny, and still cheaper than original.
