FLASHING BLINKY LIGHTS BATTERIES

FLASHING BLINKY LIGHTS BATTERIES
While a few flashing blinkies are made to be used once (like glowsticks), most can be reused with a fresh set of batteries. Typical blinkies use two to three AG3/AG4, SG3/SG4, or two CR927 batteries (see List of battery sizes). Where the same sized battery is available in alkaline or silver oxide chemistry types, silver oxide is preferred as they are longer lasting. Although such batteries cost about $3-$5 at watch and drug stores, they can be had for $15 per hundred from online stores. (However, watch stores usually install the battery in your watch, which can be very difficult, while flashing blinkies are usually just 'twist, remove, replace, and twist'. With some blinkies, take care to retain the insulating plastic or tape around the outer ring of the set of two or three batteries.)
