I thought I'd give another update. That VT red camo softie was firing intermittently the other day on my
tank. I let it sit for about 2 or 3 hours and it worked like a champ when I tried it again. That and another diamond softie are both doing the same thing. Direct from the slim line charger they don't work and do the off and on firing. I let them sit for a few hours off the charger and they are great. I have quite a few batteries so knowing to let them sit awhile isn't a major problem--it's just remembering (the age thing.)
