Silly to charge a brand new battery? #5294624 12/14/19 08:06 PM

Bought a brand new Interstate 24F from Costco today for my Odyssey. Got it home and immediately threw a Battery Tender on it to "top it off". I did the same thing two weeks ago for my Mazda which also just got a brand new battery. Am I being too OCD or is this a good practice assuming the batteries might be sitting without a float charge for a month or so? I don't drive long trips at least with my car so I wanted to be sure the battery had a good start on life.

Better to be sure, will be easier on your alternator.

Not silly ... if it’s not 100% you saved your alternator the wear and tear

I will from time to time charge all my batteries. Some just 6 amps, some on my battery tender overnight.

An hour of driving will top it off just the same. If your alternator can't handle the wear and tear, start shopping for a new one too.

Not silly if it's old enough that the open-circuit voltage is lower than it should be.

I don't bother. If the voltage is that low I pick a different battery, don't want one that was sitting around for long with depressed voltage. I mean that I take a multimeter with me in any case that is not sudden/unexpected.

Actually had a parts store suggest I charge the battery when I was replacing the alternator. The idea was the battery was likely discharged and expecting it to charge the weakened / dead battery wasn't a good idea.

Depends on the car. A lot of newer cars won't fully charge the battery anymore so they can get better CAFE numbers and the batteries die early because they don't get fully charged.
