Product:
iRobot Roomba 500 battery (3500 mAh 14.4 V)
General:
I am very satisfied with BatteryChampions. I ordered a Roomba 500 compatible battery and it arrived in my mailbox ten days later! I did not have to pay any tax or customs fees and did not have to go and pick it at the post office. So nice!
About the product:
The Roomba 500 compatible battery performs as well as the original one, or maybe can hold even longer. I've had it only for a month now, so I do not know how long this will last, but so far I think that the new replacement battery might be even better than the original one.
