Self-discharging pack?

Don't trash it yet. If you are making judgment on the pack based on how long it takes to charge it is leading you astray. Any pack will take a fair amount of charge after being fully charged before the charge will terminate. Depends on the charge rate and the pack characteristics. To tell if you have a problem, charge the pack, then discharge with a charger that will read out the discharge capacity. Charge it again and let it rest for 48 hours, then discharge the same as before. If you have lost a significant amount of capacity (more than 10%) then the pack may be headed south.

Hi Red,

I've never kept track of how long it takes to charge it.

But more than half the capacity of the pack? It's a 1700 mah pack and it took an additional 865mah after sitting for about ten hours on the bench, not connected to anything.

I'll do that and see what figures I get. Thanks for your response.

Good flying, desmobob

I had a couple of NiMh packs that had been sitting around so long that they measured nothing. I left them on a wall-wart charger for a day or two until they started to show a charge, then I put them on my Swallow charger and gave them about 4-5 charge-discharge cycles (500mA charge, 300mA discharge). The first few cycles they took and gave out about 300-500mAH, by the last cycle they were giving their rated 1500mAH. So it's quite possible that with a bit of cycling your pack might come up to scratch.
