18-Volt Lithium-Ion 4.0 Ah Battery is rated 4.2 out of 5 by 14.
Rated 5 out of 5 by from typical Bosch battery packs I have been changing over from my old Bosch ni-cads, to the bosch 18 volt lithium, I have never had any problems with the ni-cads with in the 10 years I owned them, it's been over a year now with the lithium, I have to say I am definitely not disappointed in the Bosch battery packs, , think Bosch are in my mind a number one with the battery packs, or like having the battery gauge , and the charge is very impressive. I have not had the chance of using them in the cold winter weather yet, but so far I have to say, , would definitely recommend them. I am actually looking forward to trying the new 6.3 en racer coming out soon.

Rated 5 out of 5 by from Beat batteries out there These are the best batteries of any tool system. You can just tell they are designed to stand up to abuse on the job. I have 6 of them and not one has ever failed on me in 4 years. They are still going strong despite their age and constant recharging. I have used them in super cold and hot weather. Nothing phases them.

Rated 5 out of 5 by from 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

Rated 5 out of 5 by from These batteries charge faster than I could use them on a multitool, planer or impact (rotating 2 batteries, 1 on a charger 1 in a tool) The LED display is fantastic. Batteries never get hot, and seem very tough, I have yet to have any issues.

Rated 5 out of 5 by from 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.

Rated 2 out of 5 by from Good and bad I bought a 18v drill and I must say that I was very impressed by it so I ended up buying the 18v grinder about a year later however after doing some research ive found that the battery does not last long on it and now ivebfound that Bosch has a problem with the 4 ah 18v batteries which has now led me to change over to makita and I could not be happier I've even invested in the SDS drill

Rated 1 out of 5 by from rubbish brought a tool set with 3 battery's ,two packed up within a couple of months of very light use

Rated 3 out of 5 by from 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!
