pro peak constellation charger

[Danjr1]

just finished charging but it finished at 2300mAh and the voltage dropped rapidly once the charging had finished? is the battery no good?

[razerdave]

No it does that, the battery voltage is high as its putting the current in, the voltage levels out at near its stated voltage afterwards (my 18v pack usually peaks at 24v but after the beep reads about 19.5v.

[Danjr1]

how about the capacity? it seems to lack 1500mAh?!

[razerdave]

I think thats probably telling you how much its put into it to make it funny charged, the packs had charge in them already

[Danjr1]

problem. the charger was charging and discharging the battery fine but recently when charging in Nimh automatic mode (which is what ive always used) its stopping charging for no reason and making no noise to say theres been an issue? my power supply is 3amps and at times, the charger can draw up to 3.5 amps from it so my guess is that the power supply is momentarily tripping out and stopping the charge?

lower the charge rate to the nicad so you only use 3 amps from the supply ,
hi dave !

[Danjr1]

Tried that. It's saying that the output voltage is too low?

[razerdave]

That could well be the cause, I've had it happen when a fuse went on a power supply not rated for use with the pro-peak

[Danjr1]

got it all sorted now. made a stupid mistake on the settings! 12c should have been 10c! thank you all for your help!

[Danjr1]

Updated the battery to 16.8v nimh 4300mah but it's doing the same thing again! Discharge is fine but on the charge, the charger is turning off and on therefore cancelling the charge. It's a 14 cell pack so ive changed the 10c bit to 14c but other than that everything else has stayed the same (4300mah, 3amps max charge and 5m/vc or whatever that bit is!)
Thanks
