Honda Super Cub Trickle Charger Installation :
Whether it is 2020 and you are on lockdown due to a global pandemic (if you are reading this and it isn’t 2020 look it up) or you have just bought yourself the new yet iconic Honda C125A Super Cub it is a good idea to consider a trickle charger to keep the battery charged, optimised and healthy. This is especially true if you won’t be regularly using the bike – the manual states that you will only get about 10 days from the battery if you have the alarm armed – and you should have the alarm armed. If you aren’t using the alarm then you are advised to charge the battery every 30 days. You can remove the hassle by taking 20 minutes and installing a trickle charger.
The Equipment : Oxford Oximiser 900 :
I opted for an Oxford Oximiser 900 – 888 Anniversary Model. It was a mere £25 and will happily handle the Super Cub battery with ease. Be aware though – this is a trickle charger – it is not suitable for charging a completely dead battery – so if your battery is in good condition this is the tool for you. (If not you may have to look at something like a CTEK MSX 5.0 which will charge, maintain and recondition.)
Installation :
- Firstly remove this screw and then the battery cover panel – br careful you don’t want to snap any of the clips.
- Now feed the accessory lead from under the seat down through the panel so that it pops out in the battery compartment. The charging accessory fits under the seat when closed without issue as does the lead behind the battery compartment cover panel.
- Two screws hold the battery holder in place – remove them.
- WARNING : Be very careful with these ones, if you have larger hands they are awkward and (from experience) if you drop one you could be lucky and will recover it in the chain guard. If you are unlucky (from experience) it will land somewhere around the front sprocket. In that case get a mate and make the bike do a wheelie, gravity will hopefully take the bolt into the chain guard.
- Pop off the plugs and unscrew the negative terminal followed by the positive.
- Now put the positive terminal of the trickle charger with the positive of the battery and reattached followed by the negative terminal of the charger to the negative of the battery.
- Finally put the two bolts of the battery compartment back in, the front covering panel and the cover panel’s screw.
That’s it – job done. Plug the charger into the wall and connect the leads and you are good – your battery will stay charged and maintained ready for your next ride out.

Thanks for that. Got my Super Cub coming tomorrow and this is my first task.
Great news. Health to ride. Enjoy.
What a fiddly phaf that job was! Thanks for the clear instructions, helped me no end.
Glad you got sorted, enjoy your Super Cub.
Sorry guys but I tried install, not a problem, but having the electrical cord fold underneath the seat is very risky, lots of fairly sharp metal + little clearance = opportunity for pinched cord and then possible fire. I removed the cord for this reason. Better choice is take the cover off if it is sitting for more than a couple weeks, and connect alligator clips. Think safety, sharp metal, pinched cables + Battery and gasoline.
I totally agree with your point but no cord is folded anywhere.
It just sits there, and the seat closes without issue when the lead is not connected to the optimiser.
When it is plugged in I don’t close the seat, just let it sit flat. The clip of the seat keeps it off the cord and the charger connector sits outside the bike and into the optimiser.
The seat is not ‘locked’ closed when the charger is in use.
When not in use there is plenty of room for the seat to close and lock in place, just make sure the connector is towards the front of the cavity under the seat when you close it down.
Mine has been in place now for around 18 months, the lead, connector and charger plugs are unmarked and undamaged.
But I do agree with your concept, I would not be having the charger all connected up and locked under the seat, but then I wouldn’t do that with any bike.
I dropped the Honda C125A Super Cub Battery Holder Screw. Does anyone know where to find one or the part number? Greatly appreciate any help.
I dropped a screw when doing this too and it ended up inside the chain guard.
Taking it off and it just fell out.
If you have no luck with that then try here, you should get the part number. Or just phone your dealer they will be able to look it up no problem.
