Battery dead, jumpstarter/charger recommendations

[dazzer1975]

Well, I presume it is dead,

Just went out to the car and put the key in the ignition, beeps, lights flashing the works, dash lights went very dim very quick and nothing when I push the key in

As I don't use the car very often, this is to be expected tbh, so with that in mind, what jump starter and battery trickle charger/conditioner would you recommend for the 2.0 tdi 140?

Many thanks in advance
