The pump battery has been showing two bars instead of three so I’ll have to change it soon, probably on the next refill. NOW I have been going through about 150 units a day lately, so your battery milage should be better.
But two weeks for the meter on regular batterys isn’t bad (and I have lithium in it now) and three weeks on the pump. Nice to know for planning but I go no where without spare pump/meter batteries.
