Battery playing up

[philh]

Hi,
Standard ego/510 1000mah battery. Shows full charge with constant green light on usb charger but if I connect a clearomiser I may or may not get one toot out of it. The blue button lights up as normal but there is no power going to the clearo. I know it's not the clearo as I have tried loads of different ones and they all work great on different batteries.
The battery switches on and off OK with 5 clicks as normal but doesn't send any power to the clearo. I have raised the centre pin so it's not that.
Any ideas?

Probably the soldering on the wire going to the center pin has let go..If it is fairly new, contact the vendor.

If out of warranty, carefully prise out the center pin and if there is no wire attached to the end of it then that is what it is..Can be soldered back if you pull the connector off carefully.

Common failure mode in ego type batteries..

Hi,
Nope, it's not that. That was one of the first things I checked by pulling the pin right out and resetting the grommet and pushing the pin back in.

Then usually the circuit board is dead.

May not be relevant to your issue, but I did notice once that if some liquid has gone into the reservoir of the battery connection and then plugged into the usb, it can knacker the usb charger.

Same thing happened to me, when plugging a battery into charger the light was going green, but the battery wasn't charging at all. When I changed the usb wire, the battery started to charge again.

May or may not be the case for you, but always useful to know!

Hi,
Again not the problem as the usb charger charges all my other batteries with no problems.
It's got to be a duff battery but I'd like to know what the problem is so that I can avoid or fix it in future.

Is the centre connection on the battery too low, can be a common problem, have you got a multi meter.

There's a tiny Mosfet on the circuit board which is prone to failure and it sounds like that is your problem.

It is the main 'switch' in the charge/discharge circuit.

Usual practice is to swap out the board with a donor.

I should have a spare board I can send if you want to tackle it yourself, otherwise I can do it for you. It'll only cost you postage.

Hi Raid,
Thanks for the fantastic offer but I am not in desperate need of this battery (5 others and a pass through). I'll drop it in my spares box and when I can put a decent bundle together I'll send them all off to you to help anyone who needs it.
