Batteries -- from the future!

[mab]

I had understood that current 3 digit Motorola battery date codes are of the form YWW, where Y is the last digit of the year and WW is the week of the year (from 1-52).

So can someone explain how I just got a couple of brand new XTS-5000 Lion Impres batteries (NNTN6034A) with a date code of 050, which, unless I'm missing something, means they will not be manufactured until about four months from now. These were bought directly from MOL, so unless Motorola is having some serious supply chain problems they are not counterfeit knockoffs.

Am I misunderstanding the date code?

Thanks

That is normal, they pad the dates a bit.

No, no misunderstanding. As I get the story, and this has been previously discussed on this Board, Motorola puts a mfg. date on the batteries that is a few months in the future, figuring that it may be that long before the things get sold. If they did otherwise then you'd get screwed out of some warranty time. It's as simple as that.

Figured as much. But too bad they aren't can't actually ship batteries from the future -- I'd like to order some cold fusion infinity cells, but they're backordered...

Yep, it's the warranty date code not the actual manuf. date for reasons stated above.

That sort of begs the question -- is there any way to get the actual manufacture date from the battery, maybe from the Impres data? Especially for Li-ion chemistries, charge capacity loss has a strong correlation with age.

Still, it's nice that they post-date the battery date code for warranty purposes.
