EFEST 10440 350mah 3.7v LiMn IMR
These batteries are roughly the same size as a AAA battery but they are 3.7v high drain batteries so do not use them in regular home devices unless you are sure they are able to handle the power output. Improperly using these batteries may damage regular home devices that are not designed to be used with this type of batteries.
