It has now been three months since these 12v batteries received a 24 hour 2 amp trickle charge.  The Interstate reads 12.60 v and the Trojan T-1275 is still at 12.69 v.  They remain sitting directly on the concrete floor in an unheated garage.  Temperature in the garage is 36 degrees.

Four months since each battery received a 24 hour 2 amp trickle charge.  Interstate reads 12.58 volts, Trojan T-1275 has actually risen since last month and reads 12.71v.  That is a mystery to me, but used two different voltmeters and got the same result.  Maybe due to the ambient temp in the garage is 38 degrees yet the cement floor they sit on is probably the same temp as it was a month ago.

Five month update: Interstate is at 12.49 volts, Trojan T-1275 is at 12.68 volts.  A few weeks ago they were each given a load test.  Interstate is showing its age as it only put out 30% of full whereas the Trojan was at 100%.  Will continue to use the Interstate as it is still good for 2 days while boondocking when night temps are in the 40's with the furnace running a lot.  The Trojan is good for 5+ days under the same conditions.  Interstate is now officially 14 years old, the Trojan will turn 4 in August.

I hope you have included the Trojan battery in your will because it appears it will out live you!
