Just bought a trickle charger, does it hurt to leave it on the battery till ridin time, or when it says charged, take it off??

 

With a trickle charger it may never say fully charged however with the operation instructions it should say if it is automatic meaning it should shut itself off preventing a overcharged battery,if you do not have the instuctions I would disconect to be on the safe side.

 

I'd disconnect a trickle charger after the battery is charged. HOWEVER, a battery tender is just that - it will keep the battery charged automatically.

 

Some devices charge but don't tend. Some tend but don't charge. Some like my Deltran Plus do both.

 

If it is just a trickle charger and not a battery tender you should remove it after it has charged.
When I used a trickle charger, on a rarely used project car, I unplugged the light from my garage door opener and screwed in an adapter that had an electric outlet and you screwed the bulb into the end. I plugged the trickle charger into it.
It only costs a few bucks. When ever the garage door opened or closed, it activated the trickle charger, for the amount of time the light stayed on.

Yours is a battery tender, which you can leave plugged in. The OP was asking about a battery trickle charger.

Trickle charger....take it off when charged.

Battery tender......you can leave it hooked up.

 

Right on, I have a tender, after reading the freakin instructions, so question answered! Thanks!
