In October 2012 I bought a new EN-EL4a from B&H. Sometime last year (2013), and (edit:NOT)terribly late in the year, the charge life dropped from 0 to 1.

I'm using the battery in a D300/D700 MBD10 grip but I'm posting here since this is where most of these batteries are probably used (most MB-D10 owners probably use AA's).

I have had 4 EN-EL3a batteries, in D200/D300/D700 bodies and even the original D200 battery still has a charge life of 0. Similarly, the original and extra EN-EL4 I bought for my D2h retained a charge life of 0 for at least 4 years, per my vague recollection. But once they went from 0 to 1, they incremented much quicker (and now are near death).

This makes me wonder if I got a 3-5 year old battery. And it occurs to me that we don't know when production stopped, but we all know these batteries have a limited shelf life (and are not cheap!).

That leads to two questions:

1. Is there a date code on the EN-EL4a? I've looked but cannot locate one. Maybe someone has better eyes

2. I'd be interested in experiences (good or bad) of anyone who has bought an EN-EL4a since about mid 2012 or so. What is your charge life now?

Edit: this EN-EL4a also constantly demands a recal, a problem I never had with the old EN-EL4's until they were quite aged.
