Does I Need A Specific Charger For Lead-acid Batteries

 
#1

i have a lead-acid battery 12v 9.0ah and i was charging it with a dc adaptor 12v 4A do i need a custom lead-acid battery charger like in lipo's or i could just charge it this way

Now I am not sure what you have for auto parts stores but if you can find one you can get a cheap 12v battery charger..

So actually now that I think about it the short and safest answer is NO you need a proper charger for it.

thanks that why alot of batteries got damages and one nearly exploded

Using a DC supply will charge it but with no over voltage protection, no control, nothing to switch to trickle when the battery is nearly charged... not a good idea.

Yep. You over charged them and boiled it dry. Lucky you didn't get hurt.

You need a smart charger for your Sealed Lead Acid battery. Here is a URL to a good one
