<div>Flooded wet-cell deep-cycle batteries that are close to being fully discharged can't be "fully" recharged in 4 hours. If you charge them at 14.4-14.6 volts or so, they might come up to about 80% charge in that time. However, you don't want to leave them at 14.4v for much more than 4 hours, you will want to drop the voltage to about 13.6 to 13.8v, and it will take many hours (maybe 12?) to reach 100% charge. At that time, you should drop the voltage to 13.2v to maintain the charge and not boil the electrolyte.</div> <div> </div> <div>You can charge the battery at 13.6v, but it will take a lot longer.</div> <div> </div> <div>The best way to use these batteries is to have a large enough battery that you don't drop below 30-40% capacity, this will maximize the number of cycles you can get out of them.</div> <div> </div> <div>I had a link at one time with really good information about deep-cycle batteries, I'll see if I can dig it up again.</div>

The current flow will decrease as the battery voltage increases until the batt is charged fully (less than 1A current @ 14.2v). Without meters it's hard to tell - probably in the 3
- 4 hour range depending on batt size, then disconnect the jumper (dropping the Iota to 13.6v) - several more hours at this level will ensure full charge (likely not necessary), probably not good to just leave it on as batt liquid may be lost by continuous charging at even the lower level.

How long does it usually take to charge the deep cycle, or do you just keep it connected all of the time to trickle charge? Since
the Iota has no meters or output display, I have no idea how long to keep it connected and I think that my deep cycles are not being fully charged. Any help??
