I probably should have been a bit more specific. I work in a shop that refurbishes used forklifts and most of the time the batteries that come in don't need more than a few cups of water to cover the plates but have been sitting for a while without a charge. If the battery is discharged past the point than our newer chargers will start, we will use an old school dial charger to bring up the voltage to a level that the newer chargers will detect and start. We will put them through an equalized charge cycle and then check the specific gravity ( most of the time around 1230 to 1250 ) and check the voltage of each cell any cell lower that 2.00 volts is marked. We then decide if we are going to sent it out to the local battery guy or send it to the scrap man. Our problem comes from the fact that the battery companies here pretty much use the same scrap company that we use and they are giving.35 cents a pound and they will tell us a battery is not worth repair and wants to work out a scrap deal at.24 cents a pound. Also we do have all of the required safety equipment and a very nice and well ventilated charge area ( total air replacement every 10 minutes ).
