The adapter also worked with the 14.4v drill, recip saw, and work light, but it was the trim saw that I used most heavily.īased on my experience, I’d say it’s fine to run DeWalt’s 14.4 tools at 18v (at least the trim saw for sure ). So far I’ve not experienced any problems and there’re no indications that it’s about to give up the ghost running at the higher voltage. I then mounted the adapter to the DW935 with a screw and now use 18v LXT batteries on my 14.4v saw. The adapter, not the tool), I got it to fit snug. I bought one, and was determined to make it work. I charged up the old XRP batteries and literally was getting three to five cuts before each battery died.Īfter a bit of searching, I found an adapter on Amazon which would adapt LXT batteries to the DeWalt XRP tools but only at 18v. However I found myself in a position where I needed to make a ton of half-lap and cross-lap cuts in a lot of pressure treated 4x4’s and I really needed that saw. Anyway, my NiCad batteries started dying out and I wasn‘t too keen on investing into any more XRP batteries, especially since I had for the most part moved on to the Makita LXT system (18v) after a few years. I find the 5-3/8” trim saw (DW935) to be extremely useful as it’s light and left-bladed (I‘m right handed). My decision should not stop others over volting non impuls drills especially where replacement parts are available and or confirmation the motors are in any event designed for the higher voltages.Ī bit late to the game here, but about 15 years ago I bought a DeWalt 14.4v combo tool set. The impuls function works well so I wish to preserve that drill so hereon I will "baby it" to more lighter and special duties. Therefore I've decided given the special case of this drill I am better to just replace the existing cells with NiMH batteries. If I fry the tool through overvolting that will really kill the tool with availability of replacement parts difficult at best. Also the electronics in my drill uses the "impuls" electronic pulse technology and again seems limited in use to the 12 and 15.6V versions of my drill. Which in writing this makes me realise where we are over volting a tool there may be some advantage (that is risk reduction) in using the LOWER power pack versions, that is a 2 A hr 18V battery has less capability of damaging a tool than a say 6 A hr 18V pack which under load will pump more current and tend to maintain the voltage, the power, the wattage and the heat going through the tool, which is usually what kills parts - too much heat in the wrong places.Īlso I would make clear that the charger for any over volt battery will need to match that pack, and not generally be the original tool's charger, unless the original charger covers the higher volt cell as well, for example my Metabo ICS 10 charger charges NI-cd and NiMH to 18V but not Li-ion batteries so it could not be used for the AEG batteries I was considering but could be used for a NiMH 18 battery pack.Īs has been suggested I searched for information on my motor type and cannot verify it is also used in 18V drills. I agree with all you've noted except the bit I've quoted, can you confirm you have said what you intended to say, because this thread is about higher voltage batteries for lower stated voltage tools.Īlso commenting on the battery type, in overview, the battery type is relevant to the extent each type of battery has different characteristics, I do not wish to set all that out, beyond observing the voltage is the voltage where-ever it comes from, but secondly the ability of the power source to maintain that voltage under increasing load is IMO highly relevant.
