Direct replacement for Yonker YK-8000C M800

This lithium-ion pack matches the original 3.7V 1800mAh specification for the Yonker YK-8000C M800 patient monitor. It replaces part numbers 12-100-0002 and LB-03 with a single 1700mAh cell rated at 6.29Wh. The unit measures 50.1 x 48.9 x 13.5mm and weighs 99.2g.

Sustained discharge with built-in protection

Integrated circuitry guards against overcharge, over-discharge, over-voltage and short-circuit events during continuous operation. The protection logic maintains stable output through a full shift without tripping, supporting reliable monitoring sessions. ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirm consistent manufacturing quality.

Limited to devices accepting 3.7V 1700mAh packs

The connector and form factor suit only the Yonker YK-8000C and M800 models listed. Equipment requiring a different voltage, capacity or physical layout cannot use this battery. Buyers needing a higher capacity or a multi-cell configuration must source an alternative pack.

Questions about this item

Does the 3.7 V lithium cell run hot or draw extra power during continuous monitoring shifts?

The pack is rated at 3.7 V and 1800 mAh with built-in over-charge, over-discharge, over-voltage and short-circuit protection, so it maintains stable temperature and normal current draw during extended use.

What must the buyer already own for this battery to function?

You need a Yonker YK-8000C or M800 patient monitor that accepts the original 12-100-0002 or LB-03 battery pack.

Will the 50.1 × 48.9 × 13.5 mm replacement fit alongside the original charging cradle and connectors on an older YK-8000C unit?

Yes, the dimensions and 3.7 V, 1700 mAh rating match the OEM spec, so the pack seats in the existing cradle and uses the same connector without modification.
