Compatible Replacement Battery

The Cameron & Co DS-CS-RPE400MD is a lithium-ion replacement cell built for Rainin E4 and E4 XLS+ pipettes, including the Mettler Toledo variants. It matches the original 6109-031, 800-472-4646 and E4-BATT part numbers for direct OEM compatibility. Laboratory technicians can install it without tools or firmware changes.

Thermal and Power Behaviour

The 3.7 V cell delivers 1.1 Ah and 4.07 Wh, so normal pipetting cycles produce minimal heat and no audible noise. Power draw follows the instrument's own management circuit, leaving run-time consistent with the factory specification.

Decisive Specification

Capacity is rated at 1100 mAh, which determines how many aspiration and dispense cycles the pipette completes between charges. Buyers who need a higher milliampere-hour rating for extended shifts should look elsewhere.

Questions about this item

How do I install the DS-CS-RPE400MD battery into my Rainin E4 XLS+ pipette, and what step is often missed?

Open the battery compartment, align the 52.20 x 35.30 x 7.10 mm pack with the contacts, and press firmly until the latch clicks; the step often missed is ensuring the black pack sits fully flush so the 3.7 V connection is solid.

What maintenance or replacement will this 1.1 Ah Li-ion battery need over time?

The 1100 mAh cell requires no scheduled maintenance; expect to replace it once runtime drops noticeably, typically after several hundred charge cycles when the 4.07 Wh capacity no longer holds a full day of pipetting.

What is the first limit that appears during sustained, heavy use of this battery?

The 1.1 Ah capacity is the limiting factor; under continuous aspiration and dispensing the pack will deplete its 4.07 Wh before any thermal or voltage threshold is reached.
