Problem with Uniross 2700mah rechargables

[fozzybear]

I bought some of these the other day with a Uniross Sprint recharger.

In the instructions, it said from dead, they take approx 2 hours to recharge the 2700mah's. Actually it took 25 minutes and I actually went through 4 'fully' charged batteries in a few hours on Saturday.

I'm not impressed. My non rechargable Duracells lasted longer.

Does it sound like there is a problem with them or the recharger?

I remember looking at that charger but ending up going for a slower uniross one. Does that version provide a trickle charge after it is finished or not? If it does leave them in there for awhile.

Yes, it does have the trickle charge. I'll try leaving them in.

I'm just comparing them to a pair of Duracell Ultra's that I previously used. I took around 500 photos (without flash) and used all 4 Uniross 2700mah batteries. Does that sound about right or should I be getting more out of them?
