Questions about this item

How often should I replace the 2700mAh lithium cell in my Colleague Infusion Pump Memory?

Replace the 7.2V 2700mAh pack when run-time drops below clinical requirements; the 19.44Wh cell is rated for hundreds of charge cycles before capacity fades.

What stops the 7.2V pack from running the pump continuously during a long shift?

The 2700mAh capacity limits total energy to 19.44Wh, so run-time ends when the infusion pump draws that amount of charge.

Does the 69.0g battery get hot or make noise when the pump runs all day?

The lithium pack has no moving parts and built-in protection circuits; it stays silent and only warms slightly under normal 7.2V load.
