Is my battery gone?

[the_quick]

Left the bike to stand in cold garage for most part of 3 weeks and it was really cold.

Tried to start it, it was very very weak turning and would not start.

Took battery out check with multimeter 11.70V

Ok so I have put it on charge (Lidls charger), after more than 5 hours charger indicated battery is fully charged, checked again with multimeter and it shows 12.85v - sweet.

This morning checked again and it shows 12.72V - so clearly discharged a bit.

Is it normal for battery to go down a bit or is the battery gone and I need a new one?

It is normal acid battery, nothing fancy.

Thanks in advance

You're supposed to leave the battery for a few hours after charging before testing voltage. If you tested immediately after charging then again a few hours later it would be normal to see a lower second reading. That would be normal and doesn't suggest you're battery is knackered.

The standing voltage of a fully charged flooded type battery at 20 degrees c is 12.6 volts, sounds to me like a good battery. I charge them and give them 24 hours then check voltage. Checking whilsst on charge or just after charging will only show a faulty battery generally.

The surface voltage will drop off a bit over 24 hrs. Dropping from 12.85 to 12.72 is not bad at all. Your battery appears to be a little sulfated as it should have been able to reach peak voltage of 13 after charge. All in all this battery sounds fine when looking at the voltage.

Thanks guys.

Battery now in bike, started without a smallest problem
