Duracell rechargeable batteries for flash?

[gen_b.]

<p>Hi folks,<br>

<br />I purchased a set of Duracell rechargeable batteries/charger about a year ago, and never opened them. They remained in a climate-controlled house tucked away, still in their package.<br>

I opened them the other day, and have since charged them for >24 hrs, and they just aren't "charging".<br>

Are they ruined? Can I get them replaced by the company?<br>

Advice appreciated-</p>

<p>Something like this was reported already.<br>

Some chargers test for some initial charge or voltage, and if there is nothing there, they will refuse charging, presumming that the batteries are bad. <br>

I do not remember the details, but expensive computerized chargers were doing this. Yet some simpler chargers do not perform any test, and just apply the charge, thus saving the batterries.<br>

Try a different charger? Once you manage to charge once, your charger could possibly pick them up and continue using?</p>
