Aprelia Posted July 23, 2011 Report Share Posted July 23, 2011 Well, that was kinda obvious before they even released the press release - Sanyo was their bet. UR18650W2 http://www.simpower.co.nz/shop/images/UR18650W.pdf http://www.alibaba.com/product-gs/346921912/Sanyo_18650_UR18650W2_high_Power_cell_.html Cells are about $4-$4.75 a piece (that's Dewalt's cost). Passive components inside are 20 cents, and the connector and shell are a couple of bucks. I haven't seen MSRP but I predict they will be $79.99 a piece or $129.99 for 2-pack in NA. Charge rate is 1C which is good. Discharge is 10C or 16A, yielding ~32A per pack - comparable to Sonys in Makita, not impressed but "OK". I'm personally "Okay" with this battery. Cycle life is probably crap, but given the fact that it's 3Ah+ and much cheaper than A123 based batteries, it's a cost-effective solution. It's like using Ryobi NiCd batteries in Festool tools. If anyone is thinking about rigging and adapter to use it in old tools - forget about it, the new batteries don't have a low voltage cutoff circuit and you will ruin the battery on first discharge.

blubricks Posted November 15, 2011 Report Share Posted November 15, 2011 Sorry, I'm new, and after taking a further look into your site...my post wasn't necessary. Thanks. Quote Link to comment Share on other sites More sharing options...
tmccarty Posted November 20, 2011 Report Share Posted November 20, 2011 Why use a lower quality cell in the 20v max fat pack (3.0ah) than in the 20v max compact pack (1.5ah)? trying to generate cost savings to the end user? Quote Link to comment Share on other sites More sharing options...
Moze Posted July 19, 2012 Report Share Posted July 19, 2012 If anyone is thinking about rigging and adapter to use it in old tools - forget about it, the new batteries don't have a low voltage cutoff circuit and you will ruin the battery on first discharge. Can you (or anyone) go into further detail about this? I was thinking of running a couple of wires to a Black & Decker string trimmer (has a 36v battery).

lorbas Posted August 19, 2012 Report Share Posted August 19, 2012 Not an expert on the Dewalt tools here, but with the Lithium cells used in this pack it is important not to drain them below a certain voltage, otherwise they get permanent damaged. So manufacturers have to put a protection either direct to the battery or to to the tool the battery is used in. When using NiCad it doesn't really matter, NiMh also doesn't like to get deep discharged, but they loose power at the end of charge so people usually recharge early enough. There are some protected NiMh packs, though. Quote Link to comment Share on other sites More sharing options...
