Up to 19% off
New arrival
From $50.99 USD $62.99
Shipping calculated at checkout.
Fits NEC VMA80 camera body; replaces OEM battery pack for VMA series compact digital cameras.
6V, 4200mAh Ni-MH delivers 25.2Wh — sufficient for extended shooting sessions without mid-session swaps.
Connector slides into camera battery compartment with spring-loaded latch; no adapter required for VMA80.
Bench testing shows Ni-MH BMS accepts charge within camera body on first cycle; voltage stable throughout discharge.
On first install, run one full charge cycle inside the VMA80 camera body before heavy shooting — NEC's battery-remaining display needs this cycle to map discharge curve correctly.

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.

NEC VMA80 — 6V Ni-MH Replacement Battery

This is a 6V, 4200mAh Ni-MH replacement battery for the NEC VMA80 compact digital camera. It slots into the VMA80 body and restores full shooting capability when the original cell has degraded. Capacity is rated at 25.2Wh.

  • VMA80 platform fit: The VMA80 uses a 6V Ni-MH cell with a specific form factor — 88.95 x 47.55 x 36.50mm. This replacement matches that footprint and voltage rail so the battery door closes correctly and the camera's power circuit sees the expected input.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge under camera-representative loads — including flash capacitor recharge draws. The BMS held charge delivery stable and did not trip on the current spikes that occur between shots.
  • First charge cycle on the VMA80: Run the first full charge through the camera body or OEM charger before heavy shooting. Some NEC camera BMS implementations calibrate the battery-remaining display during that first complete charge cycle — skipping it can cause the indicator to read inaccurately from the start.

Battery percentage jumping erratically on the VMA80 display

The VMA80's battery indicator maps voltage thresholds to percentage steps based on the discharge curve of the original NEC cell. A fresh replacement Ni-MH cell has a slightly flatter discharge curve than an aged original, which means the camera's voltage-to-percentage translation can misread the cell state. This causes the indicator to jump — sometimes from full to half in a few shots, then stall. One full charge-discharge cycle through the camera body typically allows the BMS to recalibrate. After that cycle, the display should track the actual cell state correctly.

Flash not fully recycling between shots on new cell

Flash recycling on the VMA80 draws a sharp current spike to recharge the capacitor after each shot. If the replacement cell is new and has not completed a break-in cycle, internal resistance is slightly elevated — enough to slow capacitor recharge under rapid shooting. The symptom is a longer-than-normal wait between flash-ready confirmations, or a dimmer flash output on quick successive shots. Run two to three full charge-discharge cycles and internal resistance drops to operating spec. After break-in, recycling time returns to normal.

Frequently Asked Questions

My VMA80 shows the battery percentage jumping from full to half after just a few shots — is the replacement cell faulty?

It is not faulty. The VMA80 maps specific voltage thresholds to its percentage steps using the original cell's discharge curve as a reference. A new Ni-MH replacement has a flatter discharge curve, so the camera misreads the state of charge at certain voltage points. Run one complete charge-discharge cycle through the camera body — this gives the BMS enough data to track the new cell's curve accurately and the display will stabilise.

The flash is taking noticeably longer to recycle between shots since fitting this replacement battery — what is causing that?

Flash recycling pulls a high current spike to recharge the capacitor, and a brand-new Ni-MH cell has slightly elevated internal resistance before break-in. That resistance slows the energy transfer to the capacitor, extending the recycle wait and sometimes reducing flash output on fast consecutive shots. Run two to three full charge-discharge cycles on the cell and internal resistance drops to its rated operating level. After break-in, recycling time returns to normal.

The VMA80 drains this replacement cell faster in cold weather than it does indoors — is the rated capacity wrong?

The capacity is correct. Ni-MH cells lose usable capacity at low temperatures because the electrochemical reaction slows, which raises internal resistance and causes voltage to sag sooner under load. The camera's low-voltage cutoff then triggers before the full 4200mAh is available. Keep a second charged cell in an inside pocket when shooting in cold conditions and swap it in when the camera shuts down — the cold cell will partially recover once it warms back up.
