Find a supplier

No exact store listing is recorded for this part. Continue with the documented system parts record, the supplier directory, or contact the affiliated UK store or US store to identify the correct regional SKU. An enquiry is not a claim of current stock or that another SKU is a substitute.

The Face Mask Store (UK), USA Face Mask Store and this site have the same owner. These links are commercial enquiry routes.

Listing ≠ endorsement. Confirm availability, approval status and source evidence before purchase or regulated workplace use.

Notes

Wider operating/storage temperature range and higher cycle count than the standard 03-855 battery. Same manufacturer-listed (not officially-approved) reasoning as 03-855. unverified: Known cross-document inconsistency (RPB's own documents disagree, flagging per the ESAB precedent — see rpb-px5.yaml generationNote): the Nov-2022 US Technical Data Sheet (Form 7.20.452 R10, p.2) states minimum run times of HE(P) Speed 1 >13h/Speed 2 >8h/Speed 3 >7h and OV/AG/HE Speed 1 >10h/Speed 2 >7.5h/Speed 3 >7h for the 03-856 battery, while the 2025 CE instruction manual (Form 7.20.569 Rev 5, p.33, Table 1.5) states materially LOWER run times for the same part number — P Filter Speed 1 >10h/Speed 2 >7h/Speed 3 >6h and A2P Speed 1 >5h/Speed 2 >4h/Speed 3 >4h. Both are genuine RPB primary-source documents; which figures are current/authoritative is not established from these sources alone, so the run-time spec should be treated as needs-verification until reconciled directly with GVS-RPB.
