Hi, I have an oxford 900 optimizer charger. My cafe has a lithium 8.6Ah battery in it and the charger I don’t think is charging it fully.

Once I jump the bike and drive it then no issue, but the charger stays on trickle for weeks after the drive, but next time its just not enough to start her after sitting for a few weeks.

Any other normal battery its perfect, but it seems like its not charging the lithium enough..

It’s only a new battery last year and I have a load tester, ain’t nothing wrong with the battery BTW.

Might need to get a higher output charger, anybody come across this before..?I know the triples can be a pain to start especially after sitting for weeks on end..
