Direct replacement for vital signs monitors

This 6.0V 5000mAh sealed lead acid battery replaces the original power source in compatible vital signs monitors. It matches the exact specifications of the original battery for direct compatibility. The 1-pack unit delivers 30.0Wh of energy for reliable operation. It suits medical facilities maintaining 300 Vital Signs, 53NTO, 45NEO, VSM 530TP, 53NOP, and 450EO models.

Simple swap with built-in protection

Installation requires removing the old pack and connecting the new unit using the existing terminals. The battery includes overcharge, over discharge, over voltage, and short circuit protection circuits. Verify the compatible model and part number such as 5300-101, B11400, or OM11277 before fitting. No special tools are needed beyond standard access to the battery compartment.

Sealed lead acid chemistry limits

The sealed lead acid design provides stable 6.0V output but offers lower energy density than newer chemistries. The 5000mAh capacity and 30.0Wh rating define the runtime ceiling for connected devices. Dimensions of 106.84 x 74.2 x 51.0mm and 980.0g weight fix the physical envelope. Certifications include ISO9001, RoHS, CE, UN38.3, and MSDS for regulated transport and use.
