Increasing Capacity and Capability

[sternwake]

As anticipated, this project has stalled, now that the 4 year old Deka GC-2s are wired up with the older wiring.

Their performance would be disappointing if they were new, and not free.

They drop to 10.24v starting my cold engine, turning it slower than the Northstar, but granted they were not designed solely for such task.

Their voltage retaining ability under load, for the Ah removed, in usual overnight cycling, is not impressive. They are either not as healthy as hoped, or just not very good at this, but likely some combination of both.

The Northstar-31 AGM has basically been isolated from all loads and charging sources.
It takes over a week for its full charge resting voltage to drop to 13.06v.

Since I rarely use more than 55Ah overnight, the 75 Lbs of Northstar TPPL AGM outperforms the 140 LBs of Deka. It holds higher voltage, spins my engine quicker.

The next thing I will do is route wiring from second transpo540HD to Nippondenso alternator, but that is likely a ways off as I've got my hands full with other things, and my ability to accomplish things in a timely manner these days seems impossible.
