Battery Advice needed

[datadawg]

Zap the hawkers with high amps for a long time with a CONSTANT VOLTAGE charger. They should come back. This info came right from a Hawker Engineer when I had the same problem. They came back to life.

What does "high amps" and "long time" mean? 10 amps? 50 amps? 10 hours? 5 days? I am afraid to cook mine if too high a charge is applied for too long. Can you charge the entire pack by just connecting the charger to one battery's terminals? Or do you have to disconnect all wiring and charge each battery separately? Some kids apparently climbed into my truck and left the battery master on, not sure how long, but my batteries are dead - around 1 volts. I really hope they can be revived, I can't deal with buying 4 new batteries now!!

When dead like that, they don't always come back.
Most do.
The hawker website has a lot of great info on these.

The second video shows the charger the military bought, and had in the SATS, I believe. It was a killer. Worked like a charm. The last place I worked as a contractor, 173 Airborne, in Bamburg, we had two of these things going 24/7. The "Recycling Center was directly across the street. We would once a week go over and snatch up any Hawkers and bring them over to "save". After a few weeks, the unit never needed to order battery again.

Datadawg, those were two videos worth watching. Thanks, great job!!
