Which battery charger?

[Diddums]

I need a charger for our scooters. It needs to be able to charge up to max then trickle charge. Both of our scooters are currently dead as a doornail and I can't charge them at home, and riding them to charge the battery takes bloody ages, so I need something I can connect at work, leave it for the day and come back to a full or partially charged battery which I can charge again the next day.

Any recommendations please chaps?

Cheers

Cheers, I wanted either an Optimate or a Ctek but our local Halfords had neither so I just grabbed one of these:

My battery was at 0% and 7.4v so hopefully this charger's "recovery" mode will be able to get some life back in it!
