Hi
be aware the leaking liquid is corrosive so wash off your hands thoroughly. (alkaline not acid)
wear rubber gloves if lots of spillage
It can corrode steel springs (often happens in torches)

battery probably Zinc Carbon so not Super Heavy Duty
get a good quality alkaline battery from a wll known brand to avoide the risk of leaking batteries
