So, tonight, I was running 4 Energizer 2500s (two lighter green tops, two darker green/blackish tops) through a test cycle in my BC-700. After a few hours, two of the cells were at their discharge phase, two were still charging. One of those which was charging was above 1.5V. I didn't make note of the exact value. I was charging all the cells at 700mA, or .28C.
Well, I keep the charger next to my computer. I was watching some reruns of America's Test Kitchen, and was just about to go to bed, but came over to my computer first to check my flickr, email, etc. This was also when I peeped at the display on the BC-700. So, I'm typing away, and I hear a little noise, like a 'pfffft!' Just a burst. My first reaction, knowing about the 900 meltdowns, and that (almost?) all of them involved these lame Energizer cells was something like 'I don't need some crazy venting cells right now, on the day that my girlfriend, whom I have been dependent upon leaves me, and everything else in my life is rather sticky as well…' Didn't want a nasty mess on my hands, not today! But it was just that quick burst of sound. So, I left the charge going, and stuck by my computer to see if it happened again…
It did! Another 'pffft!' and from the general direction of the BC-700. Now, I have some papers and such over there as well, it could have been things shifting. But, I know these aren't great cells to begin with (I do have eneloops, and assuming I can find employment soon, will replace all these old, lame Energizers as well…) and I feel like >1.5V at .28C is not necessarily right. Well, I don't care what part of charge/discharge the cells were at, I yanked them all out. Maybe I'll try again tomorrow when I can continue to monitor them, but definitely not running this while I sleep.
Now, as I already mentioned, it could well have been something else making the noise. Also, no smell that I can detect… But, is it possible that my 'pffft!' noise was indeed coming from one of my cells? It's not exactly a behavior that I've heard of before…*Part of me hates to be paranoid, but the other part of me realizes that caution is a good thing…
