Standard AA and AAA Batteries are very readily available from stores and petrol stations everywhere so we've made a decision not to stock them; however, there are those special batteries and battery chargers that are just not so easy to get hold of - especially the rechargeable batteries used in lights. Companies like Lezyne and Exposure build some stunning bike lights with rechargeable batteries so it is wise to always have a spare set readily charged up.
