Rated 5 out of 5 by 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 November 22, 2014
Rated 5 out of 5 by Plenty of Power I had purchased the Bosch 18V Impact drill kit, that came with 2 "fat pack" batteries, over 2 years ago. I am an HVAC contractor and I put that impact drill, and the fat pack batteries to the test. I set tap cons, lag bolts, etc , and I'll tell you what, the drill and batteries never even hiccupped once. I think I would need to charge a battery every other day. I can't believe the longevity on these batteries. NiCad batteries are yesteryear, in comparison to the technology that has arrived with Li-ion. With my old NiCad batteries, if I left them in my work truck over 2 weeks I would have to top them off before heavy use. With these fat pack batteries, if I leave them in my work truck without using them for over 1 month, you can bet I had minimal loss in power. Trust me, I've experienced that already. I was sure the battery would be dead after sitting in my work truck, in the Florida heat over a month. I couldn't believe these batteries barely lost any power. I was impressed and a believer in Li-ion technology. One of my original fat pack batteries failed after over 2 years of HEAVY use, so I had to purchase a new one as a back up. I LOVE the new model with it's fuel gauge. Now I can see how many more tap cons I can set without guessing how much of a charge I have before climbing all the way back up my ladder. The battery gauge sure is a time saver. April 10, 2014
Rated 5 out of 5 by Lots of power I finally upgraded my twenty plus year old 12volt cordless tools. The Bosch 18v batteries seem to last forever in comparison. Very happy I upgraded to the Bosch system. I will be buying more in the future. I have recommended Bosch to many people since my purchase. November 15, 2013
Rated 5 out of 5 by 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?  September 29, 2013
Rated 5 out of 5 by at the top of its class I have a couple of these and i like the fast reload and durability.. September 15, 2013
Rated 3 out of 5 by Run Life of batteries I used Makita for many years before switching to Bosch. I am very happy with the tools. The tools are very well made but the batteries need improvement. Compared to Makita these 18v batteries don't compare. I can barely rip a 2x4 with fully charged battery and new blade. I am very disappointed!   August 15, 2013
Rated 5 out of 5 by Longevity In comparison to Ni Cad batteries by another brand, the Bosch Fat Pack batteries can't be beat. I'm an HVAC contractor, and I could set hanging straps to red iron easily all day on a full charge. The batteries also charge in 30 minutes, not 45- 60 minutes like other brands. The charger also has a built in fan to help cool the battery down while it's charging, in case it was heavily used and hot. My other brand of batteries (for another cordless drill I have), will not charge until the batteries cool off because of heavy usage. So sometimes my other branded batteries have to just "sit in the shade" for about an hour before I can even ATTEMPT to place them in the charger to charge. May 17, 2013
Rated 5 out of 5 by great for the bocsh radio It works great for my radio. Love how long it last and the power display. May 10, 2013
