I was using a cheap car battery charger, but that didn't have any sort of proper cutout/trickle mode to it, so wasn't very trusting of it. Then tried my etronix charger as it has a lead acid mode, however I never found it very effective, either cutting out with a timer limit or cutting out via a thermal trip...so gave up on that and bought a Numax leisure battery charger instead...

Think I actually picked mine up on ebay for less than most places were selling it, so shop around, but have to say it works really well, awesome little charger that I thoroughly recommend!
