Pros

The package comes with 2 usb-rechargable li batteries. After searching for and comparing various 9-volt lithium battery chargers and batteries on amazon, this battery has 2 times the amount of lasting power that my last battery had. They can be rechar...  Read More

Batteries have a label wrapped around them that makes the battery slightly larger than other 9v batteries. These batteries fit all my devices, unlike some rechargeables that are a few mm too long. These are literally the best for those pesky smoke det...  Read More

    I will try to discharge them completely and recharge to full


    Posted by a reviewer on Amazon

    These look pretty nice and charge in a reasonable amount of time but the final voltage is only 8 volts when fully charged


    Posted by a reviewer on Amazon

    Posted by a reviewer on Amazon

    Also it would be nice if there was a sentence in the instruction sheet telling the meaning of the charging status lights apparently red charging and green charged


    Posted by a reviewer on Amazon

    Now every few days i just pop one off the charger and swap it out
