Surprisingly it has a 6V lead-acid battery, not a nickel-cadmium battery as the description says, or a lithium battery as the product packaging says specified. This is a *big* plus though! Lead-acid batteries are cheaper to replace and more readily available. The battery that comes with it is only 4.5Ah, so I'll be replacing the pump with a larger battery, probably this 12Ah model: ExpertPower EXP6120 6V 12Ah - 6V, 12A, SLA, Sealed Lead Acid with F1 terminals. The 12Ah battery is too big to fit in the pump, but since it's in a cabinet I don't see a problem with placing the battery on a shelf next to the pump connected to it.
