Last year I purchased several 4 packs of AAA NiMH batteries on sale.
These were stored properly in the original package,
Got them out today and tried to charge them in a new AA AAA wall plug in unit, the charger defaulted on all of them and would not charge the AAAs.
The charger works fine because I just charged some new NiMH AAs with no problems...also the mA of the AAAs are compatible with the charger.
Why are these unused 1 year old NiMH AAAs not taking a charge?
Thanks for your help.

If they are different brands, check the + "tip" of the batteries compared to the ones that charge ok.
If there is a metal ridge or plastic around it it may not seat properly and fail to make contact in some chargers.
Inspect the opposite - end as well.
If they are the same brand as the charger I would email the battery company and ask for replacements.
