I want to buy a small 12v diesel transfer pump

I won't always have it close to a car to allow me use the car battery. So
the question is could the Bosch 12v batteries used in their cordless
equipment be used to drive this pump and if so for how long.

I hesitate to buy a small 12v lead acid battery as it would inevitably be
discharged when I wanted to use it.

Or could I get a 240v to 12v transformer to drive it as access to 240v
isn't a problem

Many thanks for all assistance

If you're not doing it that often I'd suppport the idea of a small hand
pump. For instance they one in the link below, but they do many other
models, some specifically for your task, this just happens to be that
one that I got for our wetroom sump pump backup (as the top of the sump
is higher than our room floor, and could potentially get flooded from
outside).
