That's a really good idea electro, I like the way you think. Maybe I'll try that :lol:

anyway, will my 12v 1A supply charge a 12V 7.2Ah sealed lead acid battery?

do they have the symbol for ohms , in there ..
omega?
ps howd you do dat??

 

It will, but it will take much longer than a 12V 5A supply because it will not be able to provide sufficient amperage. When I was chargin the battery w/ my power supply I was reading 4.5 amps.

will it stop charging automaticly when it is finished?

Yes. Read this whole thread and you will see that the battery will quit sucking current when it gets full, accept for a small trickle current.

How do you do it'

Press Shift and Alt then type in a number and then relese Shift and Alt

This aculy displays the charagcter of the ASCII code you enterd.So you cant enter higher than 255

Those icons are on the small numbers in the Arial font.
heres what some nembers put out.

well, with a 12 volt battery will i need 15v iv been on google and some sites say charge it a 15v. 12v will not put anything through, my multimetre says 0A, when i charge a 6v battery at 8 volts it works.

Daniel, I don't understand you, are you charging two diferent batteries? Or are you trying to charge the 6v w/ 8v and 12v?

yea i have 2, 1 6V one. 1 12V one. the 6V charges fine at 8V. at the moment my power supply will only go up to 12V and that is not charging the 12V battery. i only want a trickle, i don't want to destroy them.

do i need 13 - 15V to charge the 12V battery?

What is the voltage at the terminals of the 12V battery ?
have you measured it?
A healthy fully charged SLA battery will be above 12V

 

You should be perfectly safe charging the 12V @ 13-15V. The battery in my truck is charged to 14V. Yes, do as willib said and check the voltage on the 12v battery. If it is already at 12v and you try and charge it with 12v it won't do anything at all.

If it's any help?, the nominal voltage of a car battery is 13.8V.
