The Active Energy battery case is secured with 4 screws. The head size is not for an Allen key. It needs a T10 security bit to allow removal/replacement.
I have done that before. But felt like I was being a heathen.. lol
Find out if it has got water inside it....

lol, let me know what you find. I have one of the same type on my desk that has been here for about 2 years. It still shows one light on the test button but fails on the charger
Annoyingly I later found out it had been still under warranty wheni it first failed but I didn't check

Because my wife left the greenhouse door open and it rained on my tool box which was just inside and had water in ino idea when it was brought. But not recently as you just can't get them round here
One of my Erbaur batteries "died" on me recently, & as soon as put in the charger would go "solid green" as in full charged.
With nothing to lose I pulled it to bits (& as much as anything to gave a play & see if I could learn something).
I found all cells except 1 holding just over 4v, so I had a dodgy cell.
To experiment I hooked the iffy cell up to my recently aquired adjustable power supply (set up to charge on constant current) & had the battery steadily receiving 0.1A (its a 2AH cell) for several hours, then whacked it on again on constant voltage at just under 22v.
The reassembled Erbaur battery recovered to show 4 full bars, & I've been using it in the battery drill on and off for the last week or so on my Camper build - & it's still holding 3 bars atm.
The acid test will be if the Erbaur charger dock will recharge the pack when it gets a bit lower... but the fact the pack hasn't plummeted as soon as used - is a good indicator that the iffy cell has recovered pretty well I think.

It appears to be 9mm as opposed to 10 unless the 10mm Tory I have is defective.
Anyway the battery has been taken apart and it had indeed got some water ingress that looked like condensation.
I then got my compressor and blew things as dry as I could. Sadly things look grim after watching this video ,
which might interest @Onoff as these batteries are far more complex than they look.
The battery is fully charged but the battery circuitry won't allow the tool its fitted to to run.
I know there is circuitry underneath the PCB you can see when taking it apart and my guess is either I could not blow out all the residue or its blown something.

I can't even edit it now either.Aren't all Tories defective?

Ask a mod, although I think that it's more fun if it's leftI can't even edit it now either.

Nah, it was the old me that was interested. Now I just long for the perfect triangle of:
