Okay, the situation is we’re gonna go charge a battery at different voltage and of course at different currents. Now I want to know if there’s a relation or some sort of a formula, I just want to confirm the results, thanks.

I want my rechargeable battery fully charged all the time. If the charging time is 10-15 hours and I charge it beyond its charging time will it damage the battery?

How do you determine if a AA sized or any other NiMH is fully charged or not? Can you do it with a multi-tester? Do I measure just the voltage alone? If just voltage, what are the values for fully charged batteries?

I read an article that said charging a battery after it is fully depleted will shorten the life. It said to charge batteries when there is still a little bit of energy in it. Is this true and what is the best way to charge lithium-ion batteries??

I have an 83 Chevy s-10. Replaced battery last month, started up great. Went to start it today, its dead. No lights, no clicking sound, nothing. Put a battery tester on the battery, it had 12.9 volts but said the alternator voltage was bad. Can the alternator be bad and the battery still be fully [...]

I have a battery that I bought back in July, and yesterday I gave a woman a jump at my little brother’s school. Today, my car is completely dead. I’m pretty sure it’s my battery, because I disconnected the battery, checked for corrosion and cleaned it before I reconnected it, and nothing (I didn’t even [...]

What should the meter on a car battery charger read when the battery is fully charged

HP (Hewlett-Packard) recommends discharging fully and recharging a lithium battery because it makes it last longer whereas, Dell doesn’t recommend it discharging fully and recharging it to increase the life of the lithium battery. Which of these is right apparently?

My car broke down on me again and we’ve been charging the battery on an external charger for a couple of hours now so we can see if it was the battery or my alternator. I was just wondering if that’s typical or not for the charge to take so long.
