Battery charger

Felix · 5 Mar 2018 at 09:04

So having left the bike for 3 months the battery is now flat. Any recommendations for chargers?

I use an Optimate 2 for mine, have the leads attatched to the battery permanently, then only have to plug it in if it needs charging.

Optimate 4 I use.

Only thing I don't like about it is it doesn't give a digital readout. Other than that it's been spot on.

If you have a bike with a canbus it might be worth getting a charger that supports that so you can plug it in directly.

How do I know? Its a Bandit 650.

I use an Oxford oximiser 900, has a LCD readout so you know what it's doing, does the job well.

Thanks, I had seen those. Did it come with croc clips?

Yep they come with croc clips and a battery lead for permanent attachment.

Hmm well picked up a Oxford Oximiser 900 on the way home and it does nothing. Just sits on 0 volts and 0 amps. Put a multimeter on the battery and it reads just under 12 volts.

You've got it attached the right way, yes?

It should give you a warning light if anything is wrong, the LCD should light up and indicate if it's on bulk charge/maintain etc.

Yup, green light. I even tested the wrong way to see if it warned, which it did. Screen lights up, no mention of what it's doing.

Does it have some sort of recovery programme it's running maybe? That's what the Optimates do on a dead battery, they will try pulse recovery or something like that, so it might just be pulsing it?

Optimates will bring most batteries back from the dead great kit.

It should say on the screen. In the end I took it back and just bought a new battery. The old one was original and had been in the bike for 8 years!

oximiser 900 here also, can't fault it

CTEK MXS 0.8.

I had two Oxford Oximiser before which killed my batteries. I won't touch anything other than CTEK now, I own a MXS0.8 and MXS5.0 for my bikes, the 5.0 is capable of quick charges and charging bigger batteries - I used it on my car (big battery for a diesel) last year when it was off the road and it was spot on.

I have a Gear Gremlin (though it wasn't made by them when I got it years ago) and a maypole A4 battery charger.

I much prefer the maypole, it has a digital read out and can fast, trickle and smart charge the battery. It's also cheap at 23 quid.
