I'm hacking my Roomba 655, so I picked up an SCI interface cable to read data out.After 3 times fully charging and using the roomba for 1 1/2-2 hrs each time (until the "Charge roomba" voice prompt), here's the max charge data as the charge finishes:bat: min 263 sec 18 mV 16866 mA 1156 tenths-deg-C 358 mAH 2696 state 8 mode 3bat: min 263 sec 19 mV 16866 mA 1164 tenths-deg-C 358 mAH 2696 state 8 mode 3bat: min 263 sec 20 mV 18285 mA 133 tenths-deg-C 416 mAH 2696 state 8 mode 3bat: min 263 sec 21 mV 19510 mA 8 tenths-deg-C 582 mAH 2696 state 8 mode 3Primary termination on absolute temperature slope @ minutes 263saving bbox varsbat: min 263 sec 22 mV 17868 mA -70 tenths-deg-C 431 mAH 2696 state 10 mode 3bat: min 263 sec 23 mV 17088 mA -16 tenths-deg-C 383 mAH 2696 state 10 mode 3It has maxed out at 2696 mAh on every charge - well below the claimed 5300 mAh.I'll update review with battery life & longevity after I've had a longer time to evaluate it.
