I have seen this asked before on the harmony one thread, but I do not believe I have seen a definitive answer to it. I had one of the dreaded blue stripe batteries that would only hold a charge for 2 days max. I purchased a replacement battery from Batteries and Things and charged if for a full 24 hours (done this a few times). It comes off the charger and the battery indicator shows a full charge but less than an hour later it is signaling a low battery. I did notice that the contacts on the battery are much smaller than the ones on the original battery with the blue stripe. Was I shipped the wrong battery or did I just get a bad one?
