Ricoh NP-99 Replacement Battery 6V 4200mAh Ni-MH

Up to 19% off
New arrival
From $50.99 USD $62.99
Shipping calculated at checkout.
Fits Ricoh Caplio NP-99 battery slot across R15, R16, and 36+ camera models.
6V 4200mAh Ni-MH chemistry delivers full-frame power for extended shooting sessions without midday recharge.
Connector tab slides straight into camera body with dual locking ears — no forced insertion needed.
We ran load cycles on a Caplio R15 body; BMS accepted the cell on first insertion with no authentication delay.
On first use, charge this cell fully inside the camera body before heavy shooting — Ricoh's battery-remaining display needs one full cycle from within the body to map discharge curve accurately.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Ricoh NP-99 / Caplio Series — 6V Ni-MH Replacement Battery

This is a 6V 4200mAh Ni-MH replacement battery for Ricoh Caplio series compact digital cameras. It fits the NP-99 battery slot and is also compatible with R-Hi8, R15, R16, and over 36 additional Ricoh models. Capacity comes from our product specification — 25.2Wh total energy.

  • Caplio NP-99 platform fit: These Ricoh Caplio models share the same 6V Ni-MH power rail and identical battery bay dimensions. The connector orientation and cell count are consistent across the range, so one battery covers the full compatibility list without modification.
  • Bench tested on actual hardware: We cycled this cell through the OEM Ricoh charger and monitored BMS acceptance across charge and discharge phases. The battery reached full charge without error flags and the camera body accepted the cell without authentication rejection on first install.
  • First-use charge cycle for Caplio models: Ricoh Caplio bodies map the battery-remaining display to a charge curve calibrated during the first full cycle. Charge this battery completely in the OEM Ricoh charger before the first shooting session — skipping this step can cause the indicator to read inaccurately throughout the cell's life.

Flash not fully recycling between shots on the Caplio

The Caplio's flash capacitor draws a sharp current spike to recharge between frames. Towards the end of a Ni-MH cell's discharge curve, internal resistance rises and voltage sags under that spike. The camera throttles flash output or extends recycle time to compensate. If shots are coming out darker than expected, check the battery indicator — even if it shows one bar remaining, internal resistance may already be too high to sustain full flash output.

Battery percentage jumping erratically on the Caplio display

Ricoh Caplio bodies use voltage thresholds to estimate charge level, and a fresh Ni-MH cell has a flatter discharge curve than the camera's indicator was originally calibrated against. This mismatch causes the percentage or bar indicator to jump forward or drop suddenly rather than declining steadily. It is not a cell fault — the battery is delivering charge correctly, the indicator is misreading the curve. Run one full charge-to-discharge cycle in normal use and the indicator will track more accurately from the second cycle onward.

Frequently Asked Questions

My Ricoh Caplio shows a dead battery icon immediately after I put in a fresh replacement — is the cell faulty?

This is a BMS initialisation issue, not a faulty cell. The Caplio's battery management system maps charge state on the first read, and a new Ni-MH cell fresh out of packaging may sit at a resting voltage the camera interprets as depleted. Place the battery in the OEM Ricoh charger and run a full charge cycle before inserting it into the camera body. After a complete charge, reinsert the battery — the camera should accept it and display a full indicator.

Shot count seems much lower than expected — I'm getting far fewer frames than the rated capacity should allow. What's drawing the extra power?

Flash, continuous autofocus, optical image stabilisation, and LCD brightness all add draw that isn't reflected in a basic shot-count figure. On the Caplio, leaving the flash set to auto in mixed lighting means it fires more often than you'd expect, which hits the capacitor recharge circuit repeatedly. Switch flash to manual or off when ambient light is sufficient, and reduce LCD brightness — both cuts reduce draw noticeably. The 4200mAh capacity is intact; the extra draw is coming from ancillary systems.

The Caplio body feels warm during continuous video recording and the battery drains faster than during still shooting — is that normal?

Yes, and it is expected with Ni-MH chemistry under sustained load. Video recording keeps the image sensor, processor, and stabilisation circuit active simultaneously — a combined draw significantly higher than single-frame capture. Ni-MH cells also generate more heat under sustained current than lithium chemistries do. The warmth is the cell working within normal parameters, not a fault. If the body feels hot rather than warm, pause recording for two to three minutes to let the cell voltage recover before continuing.
