I've read some stuff about battery sulfation, and from what I understand one way to attempt desulfation is to charge the battery at 25A, then apply a 25A load and repeat the cycle a few times. My question, albeit probably a pretty silly one, is how do you apply a 25A load? Do you just hook up some kind of heater or something that draws 25A, or is there a load tester of sorts you can buy?
I've seen load testers at places like Harbor Freight but they're all rated at 100A.
I'm probably missing something obvious, enlighten me please
Thanks,
Isaac
