How to kickstart drill batteries?? HELP NEEDED

[Deleted]

I have a bosch electric drill.
The batteries wont hold a charge over-night and even when fully charged only last long enough to drive a few screws.
Used to be a good tool.
Anyone know how to kickstart them??
Cant afford new. Off work injured atm

Have you tried leaving the battery in the freezer for a couple of days before charging? This worked for my first cell phone back in the '90s when the battery was on its last legs.

Which batteries does it use? NiCad, NiMh or Lithium?

Research using mig welder on it. I done a few a few years ago. You shorted it out, then reveresed it. Put 80 amps through it de sulphate the plates or summat

Thats only with NiCad though, certainly not lithium!

Isn't it nice how Bosch make a tool that lasts a long time but change the battery shapes now and then so eventually you have to give up with it. That's my personal rant at them, I use dewalt now anyway for that very reason actually.
You can take the casing apart on the older batteries and check the cells for moisture and corrosion. Make one good one out of two bad ones. Swap spare cells out of the other battery that gave up if you still have it. Done this myself and got another year out of it. Failing that, a cheapo thing like B&Q's Pro range may get you out of trouble, then you can just launch it when you are done.

Dewalt have changed there casings aswell now i think. You can buy pattern batteries too, don't know how good they are though.

I just buy the screwfix special £90/100 with two batteries and chuck it when the batteries die. Mainly because its a work tool and i get my moneys worth out of it

Dewalt changed their batteries fairly recently causing a lot of long term 18v users to look elsewhere as they don't provide an adaptor to use the new style batteries with old kit (there's a decent market for them).
Anyway have a look at floureon batteries for your kit they get a good review from people I've met with them and are a lot less than genuine.

Bosch keep spares on stock for 10 yrs after a model ceases production.

It might be the charger at fault.?

You can buy various adaptors for the 18v DeWalt batteries. Loads on Amazon for instance.

Thanks for the replies. I will try the freezer tonight.
If that fails I'll try the welder>

I have a couple of old Dewalt drills that use the old style NiCad batteries. I rescued about dozen (supposedly non-working) batteries from work. Some are still OK , some I repaired by opening them up and swapping any duff cells for good ones. Even if you have to buy them, NiCad cells are pretty cheap and there are plenty of websites showing how to replace them.

First of all you need to check what batterys they are, usually a few of the cells will have gone bad and drain the good cells, i've re done my dewalt by opening the pack, seperating the cells and charging them individualy to sort the good from the bad them simply replaced the bad cells with (in this case) S/H 14250s from a lap top battery but as i say you need to know what type of batterys they are, you wouldn't want to charge a li-on battery with a normal lead acid charger for instance.
