"I did a test to see if the hype was justified. Waited till I was receiving a low battery warning on my DirecTV remote. Put in the sleeves and the warning went away. With continuous normal use, those batteries lasted another month and a half when normally they would have died within days of the warning."
Batteries that showed as being near dead showed full after installing Batteroo sleeve.- Grant Coleman"Went from no light whatsoever to bright as if new batteries were installed."

"I put them in a weather station base. It takes 2 AAA batteries and they last about two years before having to be replaced. The display went blank, indicating the batteries needed to be replaced, they checked out as bad on my battery tester. Used Batteroo Boost on these "dead" batteries and the station has been working over two weeks now."
