These 18 V tools and batteries are excellent.
Replacing my twenty year old 24V tools that are getting old. These new ones are a great replacement and upgrade.

worth the extra
The 1.3's are still good batteries but the 4.0's are worth the extra..for example my jobbox runs for 4.5 hrs with the 1.3,,,,11-12hrs with the 4... they are a must with the hammerdrills

Fat pack battery
So this was purchased to replace a battery that went dead prematurely. It replaced a slim battery as I would rather have the additional battery strength over a smaller lighter thin battery. The thing I really like is the fuel meter on the side of the battery to let you know the strength of the battery

Don't necessarily need
I received this as a complimentary battery with my tool, which came with two others (4 aH) and used the hammer-drill to help build a 100-foot fence. The batteries had so much capacity that I really didn't need to recharge it at the end of the day—that's what the LED gauge said.

So, while I love the huge capacity, I don't need it; I would rather have been offered a 2 aH model as well, because I use this in the shop as well, and don't need the capacity or the weight all the time.

It IS possible to register an individual battery with Bosch; I called them and they need the receipt as well as your Provantage number (given to you when you register tools). You can call to confirm at 1-877-Bosch99, which is (877) 267-2499. Bosch will tell you where to send the information.

Jobsite Radio
How long will this battery (4.0 AH) keep my jobsite radio charged for if I'm listening to music through the AUX port?
