short on power
The battery works, but for a short time only, and it does not hold a charge very well...kind of dissapointed in it...

Battery Power
So far so good. The delivery was prompt and the battery went directly to work. I believe I had to get a new one because I left the bad one on the charger too long. The charger states that it is a 1 hour charger. When I leave the battery inside the radio charger, it's comes out ok.

All 18-volt nicads are shortlived...but at least this is a good price.
I've had 8 or 9 of these batteries in the last few years. Expect to get about 2 years at most of good power than cells start to die. Used to be that the Bosch ones were always about 80 bucks and it was better to have them rebuilt at a battery shop for about 50 bucks...now Amazon's got them new for about the same price. Great!

The Blue core is only slightly better. Not much. Just more insulation. The cells overheat and die and voltage drops off per cell (about 1.5 each). Check with voltage tester....you'll see older batteries even after recharging will be quite a bit less than new ones. (around 19 volts for new)
Rules, Don't overwork the batteries, when power starts to full off recharge and replace with new immediately. Don't run 'em down. Heat kills 'em. Keep charged batteries always nearby. I love the tools esp. the jig saw and planer and skill saw. I find the Dewalt tools also good and their batteries seem slightly more powerful but my Bosch never fail...but the batteries aren't so good buy I think that's with all 18 volts. The old Makita 9 volts lasted longer by far. Bigger means less longevity. (Lithion-ion has some problems in cold on my little bosch 10.8 tools)

finally a price about what it should be...

Great product....great deal
As expected the new Bluecore battery from Bosch is great. The price from Amazon made this purchase 40% less than i could buy it for locally. Thanks Amazon!

Bosch Bluecore Battery
Batteries work fine, but they are still Nicads. Time will tell if they are better than the originals. I would prefer that Bosch would sell retrofitted Lithium batteries to replace the Nicads as have some of the other high end power tool manufacturers.
