Charging problems.

[Chris Harte]

I have set my Orion Advantage charger (the first edition) to:

Set to Nimh batteries
4500MAh capacity with a charge rate of 5amps.
3mv Per Cell
6 cell pack.
Cut off temp 35 degree celcius.

I press charge and it says check battery.

I have discharged my cells to 0.9volts on a novak smart tray and the deans are on the right way. Why isn't it picking them up

My cells are a pack of these: http://demonpowerproducts.co.uk/prod...oducts_id=1882

When I load up the battery management screen it says input 12.5v which is correct but the output says 14.2V. Does this mean my smart tray never discharged?

Any ideas what is going wrong?

I would switch off the capacity cut.

3mv Per Cell
6 cell pack.
Cut off temp 35 degree celcius.

This is too low, 40-45 degrees would be better.

What is the resting voltage across the whole pack?

This seems weird. Possibly a hardware fault.

You can't turn the capacity off.
I shall increase the temp.
I don't have a multimeter to check the resisting voltage.

I will put them back on my discharger and see what happens.

Hi Chris,

The Advantage has a low cell voltage cutoff as a safety feature - are you putting the cells on charge as soon as they come off the Smart Tray? If so, have you tried giving the cells 15 minutes for the voltage to recover before tryign to charge them again?

[glypo]

Yup sounds like dodgy hardware. 14.2 volt is impossible output voltage.

[Chris Harte]

Yes, They finished discharging and I took them off the smart tray. I left them for an hour for my driving lesson then put them on the charger.

6 cells should never read 14.2V, therefore there must be a malfunction in the unit. Do you not have access to a multimeter or another charger?

[Chris Harte]

I do have my old charger. I will give it ago with them.
I put them on the discharger and it comes up with all six lights. Maybe its charging somehow

[josh_smaxx]

Did you read the instruction on the smart tray? the lights come on and go out when there discharged.

[Chris Harte]

Yep I did read the instructions.

I had discharged the pack and then not managed to charge them yet they managed to have charge in them again.

I have come to the conclusion that the charger has had it. Oh well..

[josh_smaxx]

Once you take the pack of load the voltage will jump up from 0.9v, try putting a bit of charge in through your old charger, discharge again and put them straight on charge, like straight away.

[Chris Harte]

Yeh, I knew that would happen, but it was on the smart tray a good twenty minutes after the second discharge. So it must of took on power somewhere.
Anyhow, charger is past it and back to using my old one for now.
