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

Great Battery
I purchased this battery for my Power Box 360 Deluxe Radio. I was only getting 2.5-3 hours of use out of the Bat609 slim packs. That is just not acceptable for tailgating! The Bat620 is great! I have yet to drain it in a one time use but came close after 8 hours of near full volume use. It may be bulky attached to a drill, but no worse than the old NiCad batteries were. The fuel gauge is a nice feature. Overall great product.

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

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.

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.
