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.

WARDS 10650 / 10651 / 10652 / 10687 Series — 12V Ni-MH Replacement Battery (VAC-905)

This is a 12V 1800mAh Ni-MH replacement battery for WARDS digital cameras fitted with the VAC-905 cell. It covers the 10650, 10651, 10652, and 10687 models. Voltage and capacity match the original specification exactly — 12V, 1800mAh, 21.6Wh.

  • 10650 series camera platform: These four models share the same battery bay, connector pinout, and BMS voltage thresholds. One cell covers the full range without modification or adapter.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on camera hardware, confirming BMS handshake, full charge acceptance, and stable voltage delivery from full charge down to cutoff.
  • First-cycle conditioning on 12V Ni-MH: Ni-MH cells at this voltage can initially show a lower apparent capacity on the camera's battery indicator. Run the first full charge through the original WARDS charger or camera body, then discharge fully via normal shooting before the second charge — this lets the BMS map the discharge curve accurately.

Camera showing dead battery indicator on a partially charged VAC-905 replacement

The WARDS 10650 series BMS reads battery state by tracking voltage against a fixed discharge curve stored in firmware. A new Ni-MH cell has a slightly flatter discharge curve than a worn original, so the camera can misread remaining charge as critically low. This usually corrects after one or two full charge-discharge cycles. If the indicator still reads incorrectly after two cycles, check the cell is reaching 12V at full charge before reinserting.

Battery percentage jumping erratically on the camera display mid-shoot

Erratic percentage readings happen when the camera's voltage-threshold map doesn't align with the new cell's discharge curve — common on first use of a replacement Ni-MH at this voltage. The camera firmware interprets voltage steps as percentage bands, and a fresh cell holds voltage differently across those bands. This is not a fault with the cell. Complete two full charge-discharge cycles and the display will stabilise as the BMS recalibrates its internal reference — confirm full charge by checking for the 12V resting voltage before each cycle.

Frequently Asked Questions

My WARDS 10650 says "no battery" when I insert the new VAC-905 replacement — what's happening?

The camera's BMS runs a voltage authentication check on insertion, and a new Ni-MH cell can sit just below the acceptance threshold if it arrived partially discharged from storage. Place the battery in the original WARDS charger and run a full charge before inserting it into the camera body. If the camera still rejects it after a full charge, power-cycle the camera body once with the battery seated. A resting voltage of 12V at the terminals confirms the cell is within the acceptance window.

My shot count is way lower than expected — flash feels sluggish and I'm burning through the battery fast. Is the cell faulty?

Flash recycling draws a sustained burst of current well above normal shooting load, and on a 1800mAh Ni-MH cell, repeated flash firing between shots puts continuous high-current demand on the pack. This is normal behaviour — flash capacitor recharge is one of the heaviest draws a camera battery faces, and shot count estimates rarely account for flash use at full power. Reduce flash output level or allow a one-second pause between flash shots to let the capacitor recharge without stressing the cell at end-of-discharge. If flash recycle time is increasing noticeably, check resting voltage after shooting — anything below 10.8V indicates the cell has reached its usable cutoff.

The battery drained much faster than normal in cold weather — is there a fault with the cell?

Ni-MH chemistry loses usable capacity at low temperatures because internal resistance rises sharply as temperature drops, causing the BMS to reach its low-voltage cutoff sooner than at room temperature. This is a chemistry characteristic, not a cell defect. Keep the camera body and battery warm between shots — a jacket pocket works. Bring the battery back to room temperature before charging, and confirm it reaches a full 12V resting voltage before the next shoot.
