Anyone tried an Oxford charger? Having issues...

[Albigularis]

As above having issues with an Oxford charger. The battery in the zx10r hasn't been used in maybe 6 weeks, so it was too low to start the bike. Multimeter still said 11v left in it.

Got an Oxford Oximiser 900 and it doesn't seem to do anything. Once connected it just flashes the "recover" bit on the screen and flashes saying 10.0Volts, the amperage stays at 0.00. Left it on overnight and it didn't do anything. Battery isn't knackered as the charger has a light to tell you if it won't take a charge.

Anyone else had/heard of anything similar?

I've got the oxford optimiser 600 the lights mean nothing in relation to the battery. It does however charge it saved me running up and down the street a couple of times with my old Varadero.

I had an Oxford charger do exactly the same. From memory I plugged it into the other bike that had a fully charged battery, then (without turning it off) moved it quickly over to the dead one. That seemed to confuse it enough to start it charging.

Give that a try, maybe use a car battery if you don't have a second bike.

Some 'optomisers' wont fix a flatted battery.
Some better 'optimisers' have circuitry to handle deep discharge so can 'revive' a deaded battery. They operate by hammering the battery with full amps in pulses to knock the chemicals 'blocking' the charge and allow the charge phase to run.
Baaat.... Normally a deaded battery will only hold a more limited amount of energy than it will when new (or properly maintained).
The chemistry of the metal plates changes and that prevents batteries charging or holding maximum charge.

If you think of a battery as the original description 'Accumulator'it makes better sense. An accumulator is a storage device.

It's an Oxford product, the fact that it didn't explode and attract a swarm of pikeys to steal your bike is a bonus.

+1 on another battery. Connect the charger to the good battery, connect the good battery to the dud one, cross fingers.

I assume it's sealed (or AGM / gel) rather than a serviceable wet cell?

I tried what you suggested Matt, didn't seem to make any difference. Doesn't deliver any current to the discharged battery at all. The charger works fine on the other battery though, but the resting voltage of mine is about 10.1v, surely that's chargeable? Tempted to jump out to tesco and grab a cheapo charger and see if it works. I can't even use the other battery from the ZX7R in the 10R as its far too big.

It's almost like sometimes it doesn't even see the battery, sometimes the charger does nothing when connected to it.

I expect the charger is fully working, but if the battery was dud then the charger should tell me so...

It seems to be a sealed unit yeah.

Just off the phone with the Oxford woman, think the battery is indeed humped. Sometimes the charger won't see the battery but it works fine with two others I've tried. Gonna get something 12v and wire it to the battery and see what happens.

Either way, new battery time.

Tried connecting the two batteries together? Jump leads, +ve to +ve, -ve to -ve. Not for long, just to see if you can get the voltage on the discharged one high enough for the charger to kick in. Watch for any signs of distress or overheating from either battery.

Bin the Oximiser and buy a Ctek. Then you know you have definitely eliminated a potential problem. Cheap battery conditioners are a false economy. Oxford products are built down to a price and only exist to provide dealers with a profit margin.

These trickle chargers are more for maintaining than recovering something over-discharged let alone almost pooped.
I've got a similar Oxford charger which gets rotated around two bikes and an infrequently used mini-digger and it's kept all three in good condition for several years.

Lead acid batteries don't like being discharged at all and leaving them low for any length of time causes irreversible chemical changes which result in a vicious circle of declining performance.
The key for long life is trickle charging whenever you don't use the vehicle for more than a couple of weeks.
Any slow drain like alarm or immobiliser will soon take down a small bike battery.

[Albigularis]

Part of the problem is the bike had both a factory immobiliser and an Accumen alarm. The accident was on the 14th of August, since then it had an "around the block" run on the 19th and has remained untouched since. I didn't have a battery charger before now, but because I've only ever had use of NiMH/Li-Po cells in the RC world, I didnt expect the lead batteries to have such a bad daily drain.

11 years is great going for an OEM battery, you've got your money's worth out of it.

I can't plug the bike in when it's parked and sometimes I don't ride it for two or three weeks. I used to have lots of grief with a weak battery until I bought an Odyssey battery and a Ctek battery charge indicator https://www.ctek.com/gb/en/chargers/Comfort%20Indicator%20Eyelet%20M8. It's great - no more wondering about the state of the battery - there's a little green light telling me everything's fine.
