Need a random battery size? Then you`ve come to the right place!    This is a Panasonic LR1 Micro Alkaline 1.5v battery, yes that`s right `Micro Alkaline`. Who doesn`t love a Micro Alkaline battery? We sure love them here at Refresh Cartridges!   What`s it for I hear you say? Well, according to the box, watches (must be a big watch to fit this battery), Garage door remotes and Head lamps (that`s on your head, not a car). I`m sure they have lots of other uses but if you need an LR1 battery then look no further!
