Questions about this item

Which Schiller America vital-signs monitor models accept this 6.0 V 5000 mAh sealed-lead-acid pack?

The battery is built for the 53OTO, 53NTO, 300 and 420 Vital Signs units, matching the original form factor and connector.

Will the 106.84 × 74.2 × 51.0 mm dimensions and 980.0 g weight fit the existing battery compartment in my 300 Vital Signs device?

Yes — those measurements replicate the OEM pack, so the pack slides into the same bay without modification.

How can I confirm the replacement is delivering the rated 30.0 Wh after installation?

Power on the monitor and verify it runs on battery for the expected duration; the built-in protection circuit prevents over-charge, over-discharge and short-circuit faults.
