I have a lead acid back-up battery for an alarm system and needed an easy compact charger for it. Rather than take the battery in the garage on the full size car battery charger, this is perfect to plug in nearby and boost the battery back up. Works perfectly. It may take a while to charge a full size car battery (it's more for maintenance charging) but the battery I have is like the mobility scooter type and in half a day it is fully charged again.

If your battery is totally flat then this charger will be no good for you, my car battery was totally flat and the charger would not charge, it has 4 lights one for each stage of charging, the first light is a red flashing light which indicates the charger is assessing the state of your battery,the 2nd is a solid red light to say its charging,because my battery was so flat it would not start to charge it, so i used my motorbike charger on my car battery overnight which put enough charge into my car battery so i could then use the charger this review is about, the charger charged my battery up fine, but just beware if your battery is totally flat.

Have my doubts as 12v car batteries normally get around 14.7v to charge on the vehicle. These are rated 12v so doubt they will charge at all. They may be switch mode too as they state not to use as power source. (shock hazard as most switch mode work by chopping the mains square wave and do not use a transformer) All in all in my view not a wise spend of £15.

I have had it charging a flat arm 12v battery, just 15 months old, occasional mobility scooter use. It has been connected for three days it is still flashing red and no charge is showing.
