Been price shopping batteries. Found WM to be the best price. Went to get the $85 one and they were out of my size.

Finagled a $55 one out of the locked rack ;). Newest they had was 08/21 so I grabbed that one. Made in Korea. Got it home and for fun checked the voltage. 12.07v!

It's on the charger now. We shall see how it is in the morning.

Sure is heavy. Much heavier than the JC one it replaced.
 
Good luck with it, I am sure it will take a charge and last through the 1 year warranty. I bought 2 deep cycle batteries last year at the same time. 1 had the current month date and 1 was a month older. the older 1 was at 12.45v and the newer at 12.65. They both charged up and ran my trolling motor about the same but after 6 mos I noticed the older one consistently discharged faster in the off season. It may just be a manufacturing defect but I always wonder if there is more sulfation in the older one.
 
I read a 24 hr initial charge makes them last longer, but out here heat does them in at the 3 year mark unless the vehicle has a trunk-mounted battery.
 
That stinks. It’s already sulfates, possibly irreversibly so due to sitting for a while.

unfortunately the only real way to know how bad is to know what the nameplate Ah rating is, a similar good condition battery Ah value is, and the Ah value of this battery.
 
I skored this little battery charger at a yard sale a few weeks ago. So far it seems to work great. It's doing it's thing now.

According to the sticker it's only 2 months old. It was clean,not dusty like it had been there forever. I will load test it tomorrow after charging.

It could have a high impedance internal short already.

Even a few days, let alone a few weeks or more at less than 100% SOC sulfates the battery.
 
This is why I always bring a DMM with me to buy batteries or have them check the voltage for me if I’m away from home or the replacement is unexpected. A voltage check doesn’t tell the whole story, but I think we can all agree that we’d take a brand-new battery reading 12.7VDC over anything less, if given the option.
 
Deep cycles seem to self-discharge (run down during unconnected storage) faster than regular batteries.

You are being unrealistic. Very few battery sellers top off charge every few days and if/when they do, it was not at 100% SOC. Isn't even viable when coming via container ship which used to take 40+ days factory to store, but today who knows!

We'll probably be seeing more and more of these sitting at low charge state batteries from overseas soon, considering all the container ships still waiting to deliver cargo, and a trucker shortage. IMO, take what you can get.

A lead acid battery sitting open circuit shouldn’t require top up every few days.

There’s a vast difference between sitting at 12.5-12.7, which is every battery I’ve bought since forever, and 12.07.

It’s not excessive expectations for an item that can be ruined and will go bad, to be topped up. Is it too much to ask for meat and vegetables to be kept refrigerated?
 
From what I've been told, the little round date sticker on the top is the month that the battery was recharged somewhere in the distribution cycle, not its production date. The date of manufacture is probably stamped on the case somewhere.

Yes but note what i wrote, distribution chains have been disrupted so they're sitting longer in between charging opportunities.

It's a bit different with produce, merely having in a refrigerated truck to get from farm to store, and stored in a refrigerated room until put out on the floor. Doesn't require hands-on manipulation of individual vegetables like it does batteries.

Batteries, you'd expect them to be charging inside a ship container for over a month? Odds are what happened was there is limited stock and the turnover is happening before the store had their weekly/whatever recharge interval so it makes little difference whether it left the store before that charge and is charged by the owner, or hit about the same low voltage before being recharged by the store so it is higher when the customer gets it. I mean in the present with the distribution chain disruption, not how things used to be in the good ole days.
 
^ You've merely linked the now years old, long standing issue, not the current problem today that is interrupting supply chains.

Today, there are stores running out of stock of several things they never were before covid, and record #s of container ships waiting outside ports to deliver, far more than a couple years ago for the reasons weberlogistics wrote about.

Distribution chains have been disrupted. All the same, a battery that OP said had an 8/21 date sticker on, shoukd NOT be reading 50% SOC. I have a lot of cars that sit, and they can go weeks if not months,mand still be in the 12.5-12.6v range with the quiescent draw of a quartz clock or a stereo memory. No reason why a new battery with no load or connection at all should be so far drawn down unless something isn’t right. A little FOD in the bottom of the cell could create a path for a high impedance short thst dissipates just a tiny amount of energy. Or It could have been overlooked for maintenance. Or something else.

Regardless, lead acid batteries sulfate if they sit at anything but full state of charge. It’s worse as it gets further from full. 12.07V is not a good point to be existing at. It tells me that it has sat at low enough soc to sulfate for a long time. It may not appear to be an issue now, and OP has charged it, but in the long run it may affect life.

Blame it on whatever you like. Something isn’t right, and it either was not remediated at many points along the way, or something is wrong with the battery…
