I have a few 12v 7ah batteries that i need to have charged

this charger will do the following :-

at 500ma (half an amp 0.5A) it will push current into a 7ah (7 Amp per hour)
sealed battery at a rate of 0.5A Per Hour and should take about 14 hours to do the trick
"theoretical values" ! dont scream at me!

add 10% for better results to the time,
so about 15hr and 24min to fully load your 12v 7Ah battery.

7 Amp per hour = 1 amp drawn for 7 hours OR 7 Amps for 1 hour (and theoretical! use again)

remember safety - charge in a well ventilated space* if the battery goes bang what is it
standing on! (petrol cans and old rags?) use an RCD device* and have a fire alarm in the room*
don't throw water on an electrical fire! use a powder extinguisher or co2

Purchased this to charge my son's 6v electric toy motorbike. Works fine, although thanks to another very helpful review I did follow the advice that to charge a 12ah battery it needed a full 24 hrs (ah of item divided by 0.5 amp by hour of charger = time needed to fully charge). That said once charged it seems to be lasting a good long time. 4 stars because it would helpful if the light went out or changed colour when the item was charged. But using simply maths works ok too.

This charger is weak if you are willing to charge an lead acid battery. When I bought the battery, it shows you the picture of this charger as if it works with it. I put the charger for 72 hrs and didnt charge 10%. Had to send it back and buy another charger!!!

I occasionally need to be able to pre-charge SLA batteries in solar powered devices, and this is ideal. Great price and good service.

Trickle charging my motorbike battery but after 10 minutes I noticed that the power light had gone out and that was the end of that! What a waste of money

Works as long as motorised trike is plugged in but that's pretty useless for little one who wants to ride around on it.
Does not actually charge the battery. Redundant piece then.
