I just picked up a SoShine SC-S7 charger to get a rough idea of capacity on laptop pulls. It's currently on sale at Illumination Supply for $14.99 -BLFuser discount + a little shipping charge.
Here is the review by HKJ if anyone is interested.
By the way, my Sony pulls are so far holding their voltage. Still letting them sit until their full week of rest is done.
