Costco GC2 Batts
Well, One of my 4 year 4 month old GC2s from Costco just coughed up a cell during a cold Coast camp trip!! Sure I could buy another $86 Batt,, but I would still have a 4+ year old one.. Ordered two ...

The average life of a properly cared for quality GC220 golf car service battery is 700 cycles.
Even under maintenance only conditions 52 months is quite enough to allow a 5% antimony battery to vigorously disagree with its new neighbor. There is one trick however than mustn't be allowed to believe it will automatically agree with the batteries and make them friends.
Connect the batteries in series. Six cells. No need to do this test disconnected but it is very necessary to isolate the linked batteries to chassis negative or positive. Six cells in series.
Charge both batteries to their max fill point.
Let them sit for a week after charging them. Then measure 3 cell voltage totals for both batteries - two voltage readings.
.15 fifteen one hundredths of a volt difference is the go-no-go line voltage limit. Then during the remaining lifespan of the old timer repeat this test every Spring.
People hate hydrometers. I dislike going to the dentist but I will be darned if I will suffer a toothache.
As long as those 2 batteries remain reasonably close in voltage and electrolyte density tests keep using old with new. The alternative of course is to purchase a second battery.
