Nikon EN-EL21 7.4V Replacement Battery for 1 V2

Up to 17% off
New arrival
From $18.99 USD $22.99
Shipping calculated at checkout.
Fits NiKon 1 V2 mirrorless cameras and replaces OEM battery EN-EL21.
7.4V, 1020mAh capacity powers the sensor, autofocus, and LCD screen for extended shooting sessions.
Connector slots into the camera battery compartment with a positive contact alignment — no locking tab required.
We ran this cell through three full discharge cycles in the camera body; BMS accepted the handshake and displayed accurate charge state on the first power-on.
On initial install, charge the battery once via the camera body before heavy shooting — Nikon's BMS requires one in-camera charge cycle to calibrate the fuel gauge for accurate battery-remaining display.

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.

NiKon 1 V2 — 7.4V Li-ion Replacement Battery (EN-EL21)

The EN-EL21 is the factory-spec battery for the NiKon 1 V2 mirrorless camera. This replacement cell runs at 7.4V with 1020mAh (7.55Wh) capacity — matching the original cell's output for the sensor, autofocus, and LCD systems. It fits the 1 V2 body directly with no adapter or modification needed.

  • NiKon 1 V2 compatibility: The 1 V2 uses the EN-EL21 form factor exclusively — the voltage rail and connector pinout are specific to this model. No other NiKon 1-series body shares this cell, so there is no cross-fit risk with other cameras in the lineup.
  • Bench tested on actual hardware: We cycled this cell through the 1 V2 body and the MH-27 charger. The BMS completed handshake on first insertion and battery-remaining indicators tracked consistently across full discharge. No false-low readings appeared during testing.
  • First-cycle charge in-body: Seat the new cell in the 1 V2 body and run one full charge via the camera before heavy shooting. The 1 V2 BMS maps its percentage display to the cell's discharge curve during that initial in-body charge — skipping it can cause the indicator to read erratically from the first session.

Battery percentage jumping on the 1 V2 display after fitting a new cell

The 1 V2 tracks charge level by mapping voltage thresholds to percentage steps. A new cell's discharge curve does not always align immediately with the camera's stored reference — especially on the first partial cycle. This causes the indicator to skip steps or drop suddenly between shots. Running one full charge-to-discharge cycle inside the camera body recalibrates the threshold mapping. After that cycle, the display stabilises and tracks the actual cell state accurately.

Shot count lower than expected during continuous AF or burst shooting

The 1020mAh rating reflects steady-state draw, not peak-load conditions. Continuous autofocus, burst mode, and LCD-on shooting each pull additional current beyond the baseline spec. The 1 V2's phase-detect AF system draws particularly hard during tracking sequences, compressing the available shot count noticeably versus single-shot use. Switching the EVF off when shooting in bright conditions and limiting continuous AF to active tracking sequences reduces per-shot draw and extends the charge between swaps.

Frequently Asked Questions

My NiKon 1 V2 shows a dead battery icon immediately after fitting this replacement — is the cell faulty?

Almost always, this is the camera's BMS running an authentication check on a new cell rather than a genuine power failure. The 1 V2 performs a voltage handshake on first insertion, and if the cell has not completed an in-body charge cycle, it can reject the reading and display a dead-battery warning. Remove the cell, reinsert it firmly until it clicks, then charge fully inside the camera body via the MH-27 charger — the icon clears once the BMS completes its first full cycle and accepts the cell's voltage reference.

The battery percentage on my 1 V2 drops from 80% to 20% in just a few shots — what's causing that?

This is a threshold-mapping issue, not rapid capacity loss. The 1 V2 stores voltage-to-percentage reference points calibrated to the original cell's discharge curve. A replacement cell discharges along a slightly different slope, so the camera's indicator hits a low-voltage threshold and jumps down several percentage steps at once. Run the new cell through one complete charge-and-discharge cycle inside the camera body — do not stop the session partway. After that single full cycle, the BMS updates its reference and the percentage display tracks steadily.

Flash recycling on my 1 V2 feels noticeably slower toward the end of the charge — is that normal?

Yes, and it is specific to how the flash capacitor recharges. The capacitor draws a large burst of current each time it refills after a flash fires. At full charge, the cell delivers that current with minimal voltage sag. As the cell approaches the lower end of its discharge curve — typically below 7.0V — internal resistance rises and the capacitor recharge current sags, extending the recycle gap between shots. This is not a fault in the cell. Swap to a fresh cell when flash recycle lag becomes noticeable; the camera's battery indicator will typically show one bar or less at that point.
