Man this batteries rock. I have used these batteries on everything. kids 4 wheeler, night lights, airplane lights, standby power, dc to ac inverter, jump start my motorcycle, tractor, jetski, the sky is the limit. just connect them in parallel for as much power as you need. These batteries are the best bang for the $$$$$$. Power to weight to $$$$$ Ratio is the best money can buy. Period. THANK YOU ALL-BATTERY.COM FOR SUCH A GREAT PRODUCT.

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.
