fly boy3 Posted January 31, 2019 Share Posted January 31, 2019 Hi all, I have an old drill that I think is on its way out. It has a 14v nicad battery, and is used very infrequently. It takes about 4 hours to charge then the charge red light turns green. The odd thing is if I switch it off then on again,the charge light turns to red and stays red for hours. Any comments greatfully received. Thanks Quote Link to comment Share on other sites More sharing options...
PatMc Posted January 31, 2019 Share Posted January 31, 2019 The battery's knacked*. This is a technical term meaning you need a new battery. Probably cheaper to get a new drill with lithium battery from Aldi or Lidl. Although do a search for the drill on ebay to see if there's any replacement batteries at reasonable price.

Braddock, VC Posted January 31, 2019 Share Posted January 31, 2019 Change the battery, i changed mine for a lipo opening the battery container to charge. What a difference the anaemic old drill is now a useful power tool. The only downside is that the motor heats up pdq (I think it's down to the brushes).

fly boy3 Posted January 31, 2019 Author Share Posted January 31, 2019 Thanks both. You are right, should get a new one or fit a lipo as Braddock suggested. Thing is its used so little that this could be the problem. Cheers Quote Link to comment Share on other sites More sharing options...

Piers Bowlan Posted February 1, 2019 Share Posted February 1, 2019 A replacement battery will cost you more than a new Lithium cordless drill and charger from Aldi or Lidi (they are available from £27!). If you can go to £80, personally I would get one of these which comes with two batteries and will probably be a lot more satisfactory. It will last forever - I am a fan of Bosch.

SONNY MONKS Posted February 1, 2019 Share Posted February 1, 2019 I have the bosch IXO,ONLY 3.6 V,But i find them compact.easy go in the toolbox,ideal for wing removal screws,and if you buy the hexagonal drill bits good for drilling.

Dad_flyer Posted February 1, 2019 Share Posted February 1, 2019 I have the same, a 14v with dead battery. Replaced it a few years ago with a new Bosch as that was cheaper than a new battery.However, now that I fly, and fly electric, I have batteries and connectors and wiring. It should be possible to use a 4s for a 14.4v drill. The max charge voltage if 12 Nicad is about the same as max for a 4s, but it might be safer using the 4s at 4v/cell not 4.2 max. I should try putting a connector on the drill, then I could use any battery I have anyway. Just now it is snowing and child_nonflyer and child_flyer and I need to be outside!

Gary Manuel Posted February 1, 2019 Share Posted February 1, 2019 You could always do something like THIS. I'm very happy with the results. Quote Link to comment Share on other sites More sharing options...
Dad_flyer Posted February 1, 2019 Share Posted February 1, 2019 That's exactly what I was thinking, but have not got round to doing. Quote Link to comment Share on other sites More sharing options...
kc Posted February 1, 2019 Share Posted February 1, 2019 It's worth trying to get all your cordless tools using the same batteries, therefore seasonal tools like hedgetrimmers get their batteries used in drills etc in the winter. Constant use improves the life of nicads so probably the same with newer types too. But the real advantage is having several batteries available for either tool.

I'm very happy with the results. +1 Wish i had thrown away the nicads years ago. It gives new life for a tired 4s battery no longer any good for flying! I go for weeks between charges now and its always ready to go, never flat. Quote Link to comment Share on other sites More sharing options...
Simon Feather Posted February 13, 2019 Share Posted February 13, 2019 I had a similar problem with a Bosch cordless drill, battery pack stopped accepting charge. Bosch replacements were silly money, no-name replacements from Fleabay were a bit better; but simplest solution was to take the battery out of the plastic case and retrofit the battery case with an XT60 plug; now it's much more powerful than before when driven off an old non-flightworthy 3S 2200.
