Went to Costco(Johnson) and Can.Tire(Exide).
Little stickers white background are attached to every battery,
e.g.F2 on top half of circular sticker.12-00 on bottom half.If one say 11-0,is it older than 6-01.Is this the date that the battery must be charged again by the shop?
FWIW,costco have batteries6-0 (stale?)while Can tire have fresher batteries if the above assumption are correct.

Just my 2 cents.

Don't know if a sticker would mean much.

12 volt batteries contain 6 cells; each cell
optimumly produces 2.1 volts. 6 x 2.1 = 12.6
volts - optimum voltage for a battery that's
been inactive a bit, say overnight. This 12.6
figure is straight out of some tech schools books I have. I've seen batteries read 12.7
& slightly higher after sitting overnight.

If one of these off-the shelf batteries you're interested in read 12.6 volts, I'd say you're at least starting off with a healthy battery. Regards.
