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.
