The comment about murdering my batteries may have been a little premature. To be honest i'm not sure i actually did. I assumed i did at the moment because of the way i was using/charging them. Iv'e since ordered a hydrometer and a load tester, which should be arriving today, so i'll be able to confirm both batteries health
They should still be under warranty. If one is bad i will try to get it replaced.
Because if i did indeed kill the Trojans i think i understand how. Iv'e since taken steps to solve the problem.
The Trojans were located under the main settee in the boat
and would seriously off-gas during charging. It would burn my eyes if i was in the boat and charging the batteries. Because of this i would not properly charge them the way they should have been and would leave them in a partial state of charge for long periods of time.
There was no other location i could put them at the time. The past couple of weeks i have been making a place for them in the aft part of the boat under the cockpit
where a water heater
used to be. It has good ventilation and fans i can use to vent the space so charging batteries 'properly' will no longer be an issue if they offgas a bit.
If the Trojans turn out to be good i'll put them in this location and put them back into service. The Firefly, since its sealed will go under the settee where the Trojans were and will be my backup battery.
From what iv'e read about the Firefly's, they were designed to be able to go longer periods of time sitting in a partial state of charge with less negative impact.
