Hi, I bought this laser off wickedlasers, but I came with no specs, like what kind of batteries it needs, I only know it uses AA ones, but it doesnt mention what voltage it uses,, I've been using normal 1.5v alkaline batteries but I was planning to buy a 3.6v lithium batteries, before I do, I want to be sure this laser can support that voltage, can somebody give me advice? Thank you
