landmannnn Posted August 28, 2010 Share Posted August 28, 2010 What do you guys do with your cordless electric drills when the batteries die? I seem to have 4 decent cordless drills and about 10 useless batteries, just one good one left. A mixture of 14v and 18v. I do object to spending best part of 100 quid for a couple of batteries. Do I replace the whole lot with a premium brand hoping the batteries last longer? Or do I buy cheaper one and sling it in 18 months? Quote Link to comment Share on other sites More sharing options...
SiWhite Posted August 28, 2010 Share Posted August 28, 2010 I have Ryobi One Plus kit which I have owned for over 3 years - still going strong. I bought thier Li-Ion batteries a year or so ago and don't anticipate they'll need replacement for a few years yet. Quote Link to comment Share on other sites More sharing options...
bishbosh Posted August 28, 2010 Share Posted August 28, 2010 For some daft reason, batteries are more expensive to buy on their own than a drill and two batteries - last time I wanted a Bosch 14.4v battery - sixty something quid or £50 for the drill and batts from Homebase....? You could try the old "touch it with your welder " trick (not an euphamism) but personally I am not that brave...... Quote Link to comment Share on other sites More sharing options...
MrKev Posted August 28, 2010 Share Posted August 28, 2010 1. I modify and old battery by fitting a plug on the back of the battery so that I can connect external power in 2. I tape velcro to the base of the old battery 3. I attach using said velcro a model helicopter Lithium Polymer battery back and have a cordless drill that seems to perform better that it did on it's original battery. I often run my 18V drill on an 11.1V Lithium Polymer with perfectly satisfactory results, though I generally run it on a 14.8V pack. About 20 quid for a suitable battery pack.

landmannnn Posted August 28, 2010 Author Share Posted August 28, 2010 You could try the old "touch it with your welder " trick (not an euphamism) but personally I am not that brave...... Tried that. The batteries seemed fine, then a week later back to dead again. Quote Link to comment Share on other sites More sharing options...
sotal Posted August 29, 2010 Share Posted August 29, 2010 I had a 12v cheapy one that died, I removed the battery and hard wired a length a wire in with crocodile clips, so it can be connected to a 12v battery - mainly used in the caravan as a leg winding tool and a screw peg extractor. I've never dared to the welder trick. I wouldn't ever bother with cheap drills again. Not only do the batteries run out quickly but the drill just doesn't perform they just feel like toys. Last time I needed a replacement I opted for a pair of second hand Makitas from ebay. They're 2006 models and came with two batteries each and a charger each. They're Nicad batteries so not the latest technology but I figured with 4 batteries I should get some use out of them before they needed replacing. They cost me £80 for the pair so £40 each so not much more than a cheapy drill. The difference is amazing - they just work, they don't give up half way through screwing a screw in, they feel solid, they have electronic breaking etc. I've had them about a year now and the batteries still work perfectly and last loads longer than any other drill I've owned Sorry if I've gone on a bit but buying the Makitas was one of the best decisions I've made with tools Quote Link to comment Share on other sites More sharing options...

Done that myself, one of the best mods I did and carry it in the land rover always! Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted August 29, 2010 Share Posted August 29, 2010 I've also taken a 12v drill with a knackered battery and made up leads to run it straight off a car battery. Works very well, but its very easy to over-work the drill, as the battery won't go flat anywhere near as quick! Quote Link to comment Share on other sites More sharing options...
R.G.P Posted August 29, 2010 Share Posted August 29, 2010 Get a Makita, I have got a package with a cordless jigsaw and 2 batteries. It's lasted about 3 years, on a farm! I use is for loads of things like a hammer when there's not one to spare!!! Quote Link to comment Share on other sites More sharing options...
