Dear Sir can anyone tell me what kind of meter should I use to monitor battery charge?Voltmeter they told is not acurate to know full charge.

Hi Guraji,


Are these lead-acid batteries? The common ones used in cars etc? If so..are they sealed or unsealed. Can you actually remove a cap and look down into each cell and see the acid inside? I hope you know NOT to touch or spill that sulphuric acid.

I do not believe there is a easy and good way.


A good charge temperature compensated controller and let it charge longer is how I do it.


The little meters are usually close enough for me.


I was never big on playing in the acid, then comparing temperature charts.

It really is too bad that the old "Delco Eye" didn't really work. Something that simple  would really be a top seller. They did at least let you know when the battery needed to be watered.


I learened first hand this spring just how great a little distilled water can make a tired battery feel. Jump started my riding mower and ran it for about 1/2 an hour draging wood and stuff and shut it off. Went out the next day and the battery was dead again. Instead of grabbing my jumper pack I grabbed a bottle of distilled water and topped it up. Turned the key and it started right up.


It is fully charged and acxts like it did when I bought it a couple years ago

I'm not so hot on playing in the acid either.


Would be nice if there were a decent cheap meter to show the real charge/amp capacity of the batteries. Not just Volts.


I mean sure a meter to show I have 12V is fine, but how many amps is that 12V going to put out before it drops to 11V? And I hate hitting them with a load tester to see if they hold up to a high load or not, just wastes power and does not really tell anything. If I hit the button and the needle drops right away I know the battery was low, if the needle stays close to 12V I know it had 50amps in it, but how much did I just waste?? And it's a pain too. And I still don't know much.

So it shows that there are no charge gauges for batteries.Mine are sulpuric acid car batteries.

Thanks

Is there someone who can tell me what meter can be installed to know battery charge?

Please help me.
