6HR61 vs 9V: battery compatibility

A reviewed side-by-side decision based on form, fit, electrical specification and application limits.

Same size · different voltage

6HR61 and 9V share a nominal size label but are not electrically interchangeable

6HR61 is rated at 8.4 V (VIDEX example) and 9V at 9 V. Matching dimensions do not make cells with materially different nominal voltages safe replacements.

Use the exact voltage and battery system specified by the device manufacturer.

About Confidence: this is a fixed score attached to a comparison rule in the catalog. It is not a probability of working, a measured success rate, or device approval. Read the verdict and its reasons; a high score can accompany a non-equivalence verdict.

Manufacturer example: VIDEX 6HR61

VIDEX identifies this Ni-MH product as 6HR61/300/1DB/8.4V, EAN 4820118294797, with an 8.4 V rating and a 26.5 × 17.5 × 48.5 mm body. This is not a universal specification for every 6HR61 or pack sold as 9V NiMH.

Check the exact manufacturer and product rating, device documentation and approved charger. Nominal voltage is not a charging setting, and a similar case does not establish terminal fit or permission to replace a 9 V alkaline battery. No charging procedure or cycle-life claim is adopted here.

Manufacturer specification: VIDEX exact product parameters.

Why this verdict

  • The nominal format matches; check actual manufacturer tolerances and the holder.
  • Nominal voltage differs: 8.4 V (VIDEX example) versus 9 V.
  • Chemistry also changes from Nickel-metal hydride to Alkaline manganese dioxide.

What to verify in the device

Check the original compartment label, the current manual, polarity, terminal style and whether the device explicitly permits a chemistry or rechargeable alternative.
