Replacement for Riester 10691 Devices

This Estry lithium cell replaces the Ri-accu 10691 pack used in Ri-modulreg, Ri-scopereg, Ri-disporeg and Ri-integralreg instruments. It delivers 3.7 volts and 2200mAh capacity in a single-unit pack. The part suits technicians who need a direct swap for original equipment batteries.

Certified Safety and Compact Form

The cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications with overcharge, over-discharge, over-voltage and short-circuit protection built in. Dimensions are 70.63 x 19.6 x 19.6 millimetres and weight is 76.0 grams. Energy content is rated at 8.14 watt-hours.

Stable Output Under Continuous Load

Protection circuits maintain steady voltage during extended diagnostic or monitoring sessions without thermal runaway. The lithium chemistry supports repeated full cycles while the safety limits prevent excessive heat build-up. Users can rely on consistent runtime for the full rated capacity.

Questions about this item

How do I install this 70.63 × 19.6 mm battery in my Riester device, and what step is often missed?

Slide the pack into the compartment matching the 3.7 V polarity markings, then press until the latch clicks; the step often missed is confirming the connector seats fully before closing the cover.

What replacement will this 2200 mAh lithium pack need over time?

The internal cells gradually lose capacity; when run-time becomes too short for clinical use, replace the entire 10691 pack — no user-serviceable parts inside.

What limit appears first during continuous operation of this 8.14 Wh battery?

The 3.7 V output drops as the 2200 mAh charge depletes, triggering the device low-power alert well before thermal limits are reached.
