These 3800 batteries are great! My Roomba can do 2 or 3 rooms well on one charge. SO worth the money! Do a little soldering and your in a new world of battery life!

So far so good. The batteries are still charging, but the process went fairly smoothly. I found that using a wide wood chisel was effective in breaking the glue seal around the plastic housing. I also had to remove the foam cushion in the bottom of the housing to get the lid back on.
