A NiMH replacement Battery pack for the Bip-Pump model ZBP-100 and ZBP-200 only.
Please make sure you are ordering the correct battery. The Bio-Pump has undergone several design changes since first introduced. Because of this not all batteries are universal.
Pumps with model number ZBP-100 and ZBP-200 use battery #ZBP-300 (the battery shown on this page). Pumps with model number ZBP-205 use battery #ZBP-315.
You can also identify the battery by the connection plug on the cable. Please look at the connector in the photo and make sure it matches the battery you have.
