- Upgrade drill batteries to lithium?
lithium batteries need a different charger so, generally, they’re deliberately a different shape to prevent them being used with the wrong one. I think Dewalt were the only ones to do a dual charger and make li-ion batteries that could be used with older tools but I think they’ve dropped that idea nowPosted 5 years ago
Unless you get paid to use tools then having as single battery isn’t much of a handicap. With older batteries you needed to fully charge them each time to prevent the batteries from failing prematurely. The benefit of li-ion is the battery charges very quickly but they can also be part charged without harming them. They take a large percentage of their charge pretty quickly – my charger has a light to indicate 80% full which it reaches in 10 – 15mins, so a flat battery is only a tea and biscuit break away from being useful again.Posted 5 years agoNorthwindSubscriber
My brother upgraded to lipo batteries for his Ryobi kit, and though it’s great for some stuff, it’s made the drills horrible to use- they’re balanced for the heavy battery, take it away and they’re really awkward.
Personally I wouldn’t throw money at green bosch.Posted 5 years agolarge418Member
There is meant to be a method of recovering ni-cads, it involves connecting across a car battery to break the whiskers that grow between the cells. Try googling for the method (ebay sellers also sell these instructions for a couple of quid).
I haven’t tried it, and it sounds like a risky strategy to me (definitely one to do outside with a lot of space around you), but it is meant to work.
I have 2 Bosch batteries that I need to recover, but as they are 14.4V, it means connecting 2 car batteries up which is both a pain in the butt, and twice the firepower, hence I haven’t done it yet….
Or spend £20-£30 on 2nd hand ebay ones.Posted 5 years agobencooperMember

I’ve not heard of that one, but methods I’ve tried successfully with ebike batteries are discharging quickly and recharging quickly several times, and also putting the battery in the freezer for 48 hours.
Some things that happen to batteries are reversible, but once the membranes start to break down there’s nothing you can do.Posted 5 years agoSvenMember
You may try out batteryfix, the guy replaced the batteries in my 9-year old B&Q drill, and they have lasted well for the last 2 years, and are miles better than those that came with the drill.
I have no connection to them other than having used them in the past, I think he charged around £40 for replacing one pack with Lithium-ion cells, and reconditioning the other pack as a backup.
