Bringing back this old ace thread.
Costco, well the $75 battery from 2022

the bed three months ago,just before the warranty ended.
They didn't have another group 58 near me ,but the manager lived out near one that had it.
Got it in two days.
Fast forward it stopped holding a charge,( I'm out on medical leave and start her once a week)
Checked alt. Its charging 14.3-7 volts at idle. Drove her for 25 mins. Shut her off and no restart,11.3 volts at battery.
Called Costco and no group 58 aval. again. So I decided to get one at wallyworld,$109.
Costco gave me a refund at the new price minus useage, I got $81 back.
Put new one in ,started her up.for five mins. Shut it did a draw test,passed , I'm happy .
Got to.say Costco.rocks!
