so an amp hr meter is 'better' than my grey matter and a watch?
furnace fan is 40 watt and 10 hrs of usage ought to be less than 50 amp hrs.
After 10 hrs of usage it's time to recharge, that can be as little as 2 days and when the furnace don't run = many days.
As a non gripper of battery life I did ask and if I had two batteries would they last 14 yrs vs the 7 for the single, the response was less that cogent.
So here's a new question, if I use 1 amp hr a day, how many days should I go before recharge, ie is going 50 days okaye or should I recharge more often like when the volt meter reads 12.2 or higher?
Weekly top charge, ain't that like every 7 days?
