Can I recharge my 12V battery?

if the battery is original from 2015, I would just change it. You should change them every 6 years or so

 

It’s possible to recover but not guaranteed. 0.06V is very low and may be toast. Are you sure you are measuring DC voltage and not AC voltage? Just want to double check. Either way, if you get a battery charger make sure you get one with a reconditioning function if you’re trying to save it.

Also, disconnect the battery from your vehicle before you charge it.

 

Probably won't be able to get any charger to recognize it's a 12v battery when it's measuring .06v

 

That is true for some chargers. My INC-700a will attempt to do it.

0.06 V is dead, unless it is a LiFePO4 in protection mode.

REVVL V+ 5G ?

 

Is that even possible? Misreading it, say reading wrong scale? Try another meter first?

 

Absolutely NOT necessary.
What makes you think that it IS ??

 

What exactly do you mean by a "battery recharger KIT" ??

As others have said, you first need to be sure you are doing the voltage measurement right.

Then if it IS less than 1 VDC, then you might as well just get a new battery.

Having a small, smart, tender type charger is a good idea though, just in general, because if you had caught your mistake sooner
a charge might have gotten you back on the road.

 

I just did the same thing recently. (Actually, my kid left the courtesy lights on inside the cabin overnight.) My battery measured 9 volts in the morning when I couldn't get the car started. Went out to home improvement store and got a trickle charger and hooked it up overnight. Started right up the next day.

 

Recovering from 9v is not as difficult as trying to recover from nearly 0v. But you should still monitor your battery as it may have been damaged during your discharge episode. Make sure the battery holds charge and won't get you stranded

 

If it really was a smart, automatic tender type charger that you got.......
PLEASE don't call it a trickle charger. That is NOT the same thing.

 

If his battery is really dead, then as the reconditioner cycles through it’s various voltages the car may turn on/off or even attempt to run at low voltages it’s not rated for. Unless you know the exact charging profile of your charger, I wouldn’t risk it. Is it needed normally, no? But I wouldn’t risk blowing any electronics in my car.

12VDC batteries usually consist of 6 cells with nominal voltage of 2.1VDC. 12.6VDC and above is good. If you can’t get above 10.5VDC, you may have a dead cell or too much lead sulfate built up. This is a pretty good article explaining the science. Best of luck reviving that battery

Also, it sounds like your charger is currently supplying 12.8VDC to the battery. You won’t know the actual battery voltage of your battery until the charger finishes or you disconnect and use your multimeter.

It needs to get to 14.4V on the charger but if it can't reach that you will probably have a dead cell.

 

Toyota says to replace if the voltage ever goes below 11.0 V, (or was it 10.0 V)? Even at 7.0 V if you took it to a dealer they would recommend replacement.

You may be able to get the voltage up with a phenomenon called "surface charge". Official testing instructions say to turn on the high beams for 30 seconds (engine off) to remove this superficial energy and measure the voltage in testing. Then compare with the referenced voltage noted above. Since it sat while waiting for the charger I have low expectations you're going to be able to revive it, but I'll keep my fingers crossed as the saying goes...

REVVL V+ 5G ?
