#REBUILD DEWALT 20 VOLT BATTERY PACK MANUAL#

I don’t plan to immerse the pack in water or other liquids, even if that does sound fun (I suppose I should find out if it floats). The lower part of the warnings is the fun part - let’s see what “suggestions” I’m about to ignore. Obvious, but this is required labeling on lithium batteries.

#REBUILD DEWALT 20 VOLT BATTERY PACK MANUAL#

There’s a 3 year warranty (which is pretty solid for a tool pack, especially if you use it regularly), a warning that I should read this list of warnings that seems to be the instruction manual (which I have, and will proceed to ignore), and a label in the top right stating that this is a lithium ion battery and that if the package is damaged, you shouldn’t transport it. The top part of the warnings is not terribly fun to read. Oooh! The back of the packaging comes with a handy list of “Things I’m about to do with a battery pack” - though I may not do all of them immediately. If you’re doing a lot of overhead work, the extra half pound might matter to you - but otherwise? This is a very nice improvement. The new pack sounds bigger than it is - it’s really only a small increase in size and weight over the old pack. You can consider this a case of “Battery technology advancing.” It’s half a pound heavier and marginally larger in all dimensions for twice the capacity. To give you an idea of how this pack compares to the more common 3.0Ah pack, I’ve compared the new pack to the 3Ah ones I have laying around and previously tore down. But, I’m going to pull it apart enough to find out what makes it tick, compare it to the other pack I ripped apart, and do an awful lot of testing to find out if it’s any good! Specifications & Size (vs 3.0Ah Tool Pack) Since this is a brand new and working pack, I’m not going to completely destroy it - I do like my tool packs for my tools. This new pack is supposed to be twice the capacity at 6.0Ah - or, as the front cover helpfully explains, “50% More Capacity vs DCB204 4.0Ah Battery.” Math! Back in 2016, I tore apart a 3.0Ah pack I had laying around - that particular one had a bad cell group (dead short in a cell - that must have been exciting when it failed), so it was quite unusable and I couldn’t really get much data on it.

I’ve looked at the DeWalt 20V Max packs before. What’s inside? Is it any good? Read on to find out! DeWalt 20V Max 6.0Ah Tool Pack This is a notable pack in that it’s (supposedly) using 20700 format cells - the first non-18650 based tool pack I’ve had the opportunity to rip into. It’s been a little while since I’ve had a shiny new tool battery to tear down! This one showed up in the mail for some analysis and evaluation - so analyze and evaluate it I shall!Īs of the time of posting, you can get 2 for $150 (shipped) on eBay - which almost certainly beats your local hardware store by a lot.
