Re: Battery drain test - result

It could fail tomorrow or it could soldier on for several more seasons.
Ok in order to eek out the remaining capacity I should stop assuming it is ok to use 60AH of an assumed 140AH capacity. I will reprogram the Link-10 to assume the battery has an effective capacity of 90AH so it should bleep after 45AH of consumption.

Battery capacities are normally quoted at a 20 hour rate so your discharge test would have been more appropriately done at a current of 3.5 amps with a view to taking 20 hours to discharge 140Ah.
Hmmm, Calder suggests a load of 10amps for a 20 hour crash test of a 200AH battery, maybe you suggested 3.5amps for a 20 hour test drain down to 50% of capacity?
