A slower (trickle) charge is better than a fast charge. Like if you use 2800mAh AA batteries and charge them in a normal charger (typically 5-6 hours), You will get a substantial life increase over charging them in a fast charger (1 hour or less). I have 3 DSLR's that prove this to be pretty accurate. You can't compare electronic batts to a gas tank. Yeah, full is full, but it's how WELL the cells retain the charge. Trickle charging is a low charge rate that keeps the battery from self discharging, thus maintaining a full capacity charge, cells lose power naturally at a rate of about 1% to 5% a day. So PC charging is more of a trickle charge than using the wall charger so it MIGHT possibly (depending on your average use) give you better battery performance.
