...both figuratively and literally. Don't let your rechargeable batteries go unloved during the summer months. It's quite easy to leave everything packed up, and know that it will be there when you go back in the fall. With the extreme heat that many places have been having it is a good idea to make sure you don't have batteries sitting out or left in remotes that may be subject to these extreme temperatures.
Personally I like to change out my rechargeable batteries during the summer so that the ones that I use during the school year can get charged up again.
