Universal 12v 500mAh Lead Acid Battery Smart Charger UPG12
Pros: Small, compact and appears to work as advertised. I am using it with a 7 ah 12v sealed lead acid battery and it charged it with no problems. I ordered it expecting it to arrive in a week or so and I had it in 2 or 3 days.
Cons: 12v 500mAh charger is sufficient but will not charge the 7Ah battery quickly, if you are in a hurry you might want a slightly bigger charger. If overnight charging is acceptable then this will do very nicely.
