How high to charge 16v batteries?

[JEXTEL 10+ year member]

i have the Kinetik batteries and i was charging them at 19-20v straight for afew days and they started smelling like rotten eggs..the 12v post protion died and now the batteries dont hold a charge..

I was told that 19v-20v is fine for charging 16v batteries?

19.3 volts should be the max voltage they see. On a normal charge 19.00 volts works well. Kinetiks are an AGM battery NOT a flooded battery. Flooded 16v you charge at a higher voltage rate

What type of charger were you using?

What amperage were you charging at?

Why would you charge your batteries for days?

The max charge rate for AGM batteries is 2.4v per cell (14.4v for 6 cell 12V and 19.2v for 8 cell 16V). Now I have seen people use higher, but it will shorten the lifespan of the battery.

youre lucky they didnt explode.

what you smell is sulfur......they are done.

I got some 16v batts for sale if you need to buy new ones

i was charging them off the 200amp alternator

and i was just driving around so they was a straight 24hrs

yes i do PM a price

If the 12v post doesn't work then you probably a cell has probably gone bad.

Is your alt fixed at a certain voltage, or is it controlled by a computer? If it varies in output like normal alts do, you should have been fine with that voltage and you should expect the batteries to hold up.

Now if your alt is set to a certain voltage by hand and does not step down after the batteries are full, then you would expect those batteries to overcharge in that amount of drive time. Basically after batteries are full, your alt should step down to a lower voltage to float them.

Now all of this changes if you have a load present on the batteries. If you are pounding audio at the same time you are driving for those 24 hours, I would expect that the batteries would not be fully charged since they are being drawn down by the audio.

How old are these batteries anyways? Did you buy them new or used? I would get a warranty swap on them if they are still under warranty.

BTW, were you in the Cannonball Run or something? 24 hours of driving FTMFL!
