Magnavox 8292 Replacement Battery 12V 1800mAh Ni-MH

Magnavox 8292 / 8293 / 8380 Series — 12V 1800mAh Ni-MH Replacement Battery

This is a 12V 1800mAh Ni-MH replacement battery for the Magnavox 8292 camcorder and related models including the 8293, 8380, and CV5320AV. It slots into the same battery bay as the original and runs at the same voltage rail. Capacity matches the original pack at 1800mAh (21.6Wh).

• 8292 / 8293 / 8380 / CV5320AV platform fit: These models share the same 12V battery bay dimensions and connector pinout, which is why one cell covers the full range. The BMS in each body communicates over the same voltage threshold, so no firmware difference affects acceptance across this group.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a calibrated bench rig. The BMS handshake completed without error flags, and the pack held voltage within spec across the discharge curve from full charge down to cutoff.
• First charge via camera body: Insert this cell and run one full charge cycle directly through the camcorder body or OEM charger before your first recording session. Some Magnavox body firmware needs this initial in-body cycle to calibrate the battery-remaining indicator accurately.

The 8292 maps its battery indicator to a voltage-threshold curve tuned to a well-used original cell. A fresh Ni-MH pack has a flatter discharge curve than an aged cell, so the indicator reads low even when charge is high. This mismatch corrects itself after one or two full charge-discharge cycles in the camera body. After that, the firmware recalibrates its threshold mapping to the new cell's curve, and the indicator tracks accurately.

Ni-MH cells can trigger the body's undervoltage cutoff if the pack has never been fully conditioned. During sustained video recording, current draw spikes cause a brief voltage sag — if the cell is partially discharged, that sag can dip below the body's 10.5V cutoff threshold and shut the camera down. Charge the pack fully before the first recording session and complete at least one full discharge cycle before heavy use. After conditioning, the cell maintains voltage above cutoff through normal recording loads.
