Questions about this item

Does the M5070A ship with any cables or a charger, or must those be purchased separately?

The listing covers the battery only; cables and chargers are not included and must be sourced separately.

The supplier title lists ND2057RC24, ND2057HD29 and ND2057QE34 — how do I pick the right one?

All three part numbers map to the same 6800 mAh 7.2 V 49 Wh specification; match the original battery label to any of those codes.

What does the 49 Wh rating mean for actual runtime in a medical device?

At 7.2 V the pack stores 49 Wh, so a device drawing roughly 7 W could run about seven hours before recharge.
