Description
This independent HSTORMB replacement listing is for the Philips PageWriter Trim cardiograph. The supplier names both 989803130151 and M4992-61105; the photograph supplied for this exact listing shows a pack marked REF 989803130151 and 12 V / 2.9 Ah. Compare those markings with your own battery before ordering. The photograph is evidence for this listing, not a guarantee that every PageWriter Trim revision uses the same pack.
How this listing was checked
Philips lists 989803130151 as a PageWriter Trim battery in its product information and cardiograph documentation. We could not confirm M4992-61105 in those Philips documents, so treat it as a supplier-listed cross-reference rather than an independently verified Philips part number.
What to compare on the original pack
- Full REF or service part number, plus any suffix or revision.
- Nominal voltage and capacity: the supplied product photo reads 12 V and 2.9 Ah.
- Battery chemistry, enclosure dimensions, terminal layout, latch, and connector orientation.
- The complete PageWriter Trim model and your facility’s approved service procedure.
Philips describes its original PageWriter Trim battery as sealed lead-acid and recommends its own specified part. This independent replacement is not Philips-branded or Philips-approved. Do not assume a different chemistry or a similar-looking enclosure is interchangeable. If any marking or physical detail differs, request a compatibility check before purchase.
Service context
The Philips service manual notes that the battery must be installed for the cardiograph to print an ECG report, even when AC power is connected. Installation and post-replacement checks should be performed by qualified personnel following the equipment manufacturer’s instructions.
