This Estry 53NTO battery is a sealed lead-acid pack rated at 6.0 V and 5000 mAh. It matches the original specifications for the Vital Signs 300, 53OTO and 420 models. The 1-pack unit is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Built-in protection limits heat and power loss

Overcharge, over-discharge, over-voltage and short-circuit safeguards are integrated into the pack. These circuits reduce unnecessary current flow during normal operation, keeping temperature rise low and preserving the 30.0 Wh capacity over repeated cycles.

Questions about this item

How do I install the 6.0V 5000mAh pack in a Vital Signs 300, and what step is often missed?

Open the battery compartment, match the red and black leads to the correct terminals, and secure the 106.84 x 74.2 x 51.0mm pack; the step often missed is verifying polarity before closing the door.

What maintenance will the sealed lead-acid 5000mAh unit need over its life?

No routine maintenance is required; keep the terminals clean, store at room temperature, and recharge every three months if the device is unused to prevent deep discharge.

What limit appears first during continuous monitoring with the 30.0Wh battery?

Runtime is the first limit; the 5000mAh capacity determines how long the monitor operates before the 6.0V output drops below the device threshold.
