Battery charging behaviour.

[stratblue]

Hi All.

I use an Oxford Maximiser 3800 for the BMW M3, Suzuki Hayabusa and the inevitable Hexhead. On the first two vehicles the 'recover' light comes on first and I see some amps flowing, then the light moves swiftly to 'maintain' via 'charging' and the amps read out drops to zero. Exactly what would make sense to an 'electricity=water' dunce such as myself. The hexhead has a Motobatt MBYZ16H fully sealed battery, when I connect the Maximiser the volts read out jumps to 17.5 ish and the amps read out remains at zero. It stays in 'recover' mode for a while then just goes to 'standby'. I've had a cursory look at all the leads and without pulling everything out for a full inspection it all looks in good order, no worn wires or disconnects. Is this what you would expect to see?

Thanks.

hi there,

my understanding is that the charger you use has to be canbus compatible...otherwise the system will exclude it from the charging circuit. My charger has a canbus compatible mode which it can get into...if you press the right sequence of buttons..

Not if connecting straight to battery. JJH

Which I do, should have pointed that out...

Pulled everything out and it's the Optimate lead attached to the battery which is knackered.

At least you have an answer. Before you bought a battery!!! JJH
