I was having my new box truck wrapped and I had a small fresh water line pop a leak while it was there overnight. It drained out the pan nicely but the demand pump kept running until the battery went dead. So I jump started the machine and let it run for awhile. But every time I unhooked the cables the machine cut off. The battery is only a few months old. So I guess my question is can a battery be drained down so far that it is no longer good? Dead cell maybe???
It could have a bad cell. I would put a charge on it overnight.. And see what happens.. If not take it back to where you bought it under warranty
No. One complete discharge should not kill the battery. Batteries have good cycle life's now days. I would place a slow charger on it over night. And by the way disconnect Inc a battery while an engine is on is a no no. The best way to check a battery is to use a vat 40 or place a carbon load on the battery. One deader cell will ruin the battery. But most likely what happenes is the battery is low on water and needs a good slow charge
If you have the time, Take it by a parts store and they can check it for you and then there will be no second guessing
just like your car; Yes a cell can rupture; break a leed; or simply go so low and need a deep charge. Take it to the nearest auto zone or pep boys; they will test it and be able to replace it.
Next time that happens and your in the field, just bump up the RPM's on the unit before you take off the jumper cables. This will increase your alternator output and engine will not die.
If the battery is that low then the voltage regulator will not keep a good charge on the battery. The battery needs to be brought up to peak first using some of the above methods. If you try a new battery, then look at the voltage regulator as the issue. As long as you have had this unit it could also be that the regulator is not working properly to keep the battery up.
I tried that and it still lost rpms and cut off. It was running intermittent so I let it charge all night last night. I'll try it this afternoon.
Yes Ara,I picked up a battery charger and let it charge for several hours and it's working fine now. From what I learned the machine can keep a battery charged but it has to be near full.
I don't know who is telling you this information but the alternator will charge your battery at the right rpm's and time. Jumping the battery will work even if the battery is fully drained. Often times a vehical jumping a dead battery has low amperage and will not reach the 12.6 volts needed because the vehical with the good battery has all the assesories running taking the needed amperage. In your situation you experienced a paracitic load. This basically means a componant was draining your battery. Knowing that gives you a diagnostic edge. Lets put it this way. If you were in your car and someone was giving you a jump and the car started. Then when they disconnected the battery and the car begins to die. Your first reaction would be to step on the gas and make sure that car stays running. Same thing happened here you just werent fast enough on the throttle or didnt give the unit enough gas to stay running. Its ok though. Hopefully your new battery charger has a nice alternator check on it. I may not know everything but I can tell you I am very good with automotive charging systems and electrical.
