Works Great

I am using this battery for a robotics application. It works great as it can sustain a 9 A continuous draw for 20-30 minutes. The technical specification section of this page is botched as the battery actually weighs ~630g (the listed weight is off by a pound).

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.
