Default JCB 24v SDS Batteries

Started using my £20 JCB 24v for a few jobs.

On a fully charged (according to the light on the charger) battery I drilled
about 6 x 6mm holes and the battery ran down to the point where the drill
suddenly stopped - seemed like some kind of cut-out operated. 5 mins later
it could be re started & I drilled another 2 holes - then it stopped again.

Would it have some kind of low power cut-out? None of my other battery
stuff has one.

It has a 'battery level indicator' on the back of the drill which showed
100% charged at the start & 80% charged when it stopped = not sure if these
things are at all accurate, seems like a gimmick to me.

Trouble is I have no experience of battery SDS drills, so I don't know if
this is usual for a battery SDS? I would have expected to drill more than
8 - 10 holes on a charge? What would a 24v brand name do on a charge?

Could be that the batteries are going through the initial stage where they
won't hold a charge until they have been charged/discharged a few times - is
this likely?

For your information mine is exactly the same. Like you I've not used
it enough to tell if the situation will improve. I have a JCB 240V drill
which has been one of the hardest tools I have ever owned. I was hopeing
the battery version might have been of similar stock

More likely an overheat cutoff on the drill motor.

I had a JCB jigsaw (230v) and it's probably the only tool I have ever thrown
away BEFORE it broke or wore out!

Perhaps you now know why it was returned...

No exaggeration, I can use my Dewalt 18v SDS for 50+ holes of 7mm, as
well as a 40mm hole through double brick - I know as I did it last
Friday when fitting out a bathroom and new skirting in a living room.
I've got 2 batteries, and expected to use them both, but havent changed
it since that morning, and also did another 10 or so 7mm holes in brick
yesterday.
The 18v Dewalt recip saw is another thing though. 20 minutes at best
when cutting tree branches.

Its not the battery by the sounds of things.
I bet if you were to set a slow speed on your DeWalt it would behave in a
similar way.
When running at less than full speed there is nothing to blow the heat out
as the fan is usually on the motor shaft.
There are some fan cooled models that have a separate motor for the fan just
to avoid this problem.
Not that I would say TMH was running it too slow but the speed controller or
thermal switch might be FU.

Yerbut this only cost me a score!

The 4 x SDS bits & the SDS/Jacbs adaptor are worth that.

Thats the odd thing, it has clearly never been used, not a mark anywhere,
not a scrap of dust, all the packaging pristine.
