    I have plenty of offbrand / burritoed batteries for almost everything. Though I try to keep the same brands together but when you need em you need em.

    it depends on the intended usage - some batteries are rated to 2A-4A continuous discharge (usual torches, "focus lights"), some rated to 10+A continuous discharge (high power torches, video lights), etc.
    if you plan to use them in the usual torch then you can safely interchange them. but you should use same model batteries if torch uses more than 1 battery.

    I like the knock-off ultrafires which I get for about 1 dollar each. They're my backups and for emergency/light use

    A chain is equal to the weakest link.

    Its a reliable one - I am using the 4-slot charger of t he same brand since 5 years. Hasn't failed on me yet but I only use it about 20 days a year ...
