Cameron & Co DS-CS-PX1685MC camera battery 1.05 Ah 3.7 V black

Compatible replacement battery

The Cameron & Co DS-CS-PX1685MC is a lithium-ion camera battery built for Toshiba Camileo S20, S20-B, S40 and S45 models. It replaces original part numbers 084-07042L-009, 084-07042L-029, PA3792U-1CAM-01, PX1685, PX1685E and PX1685E-1BRS. The cell delivers 3.7 V and 1.05 Ah for 3.89 Wh of capacity. Photographers needing a direct-fit spare for these camcorders will find it suitable.

Practical limits of Li-ion chemistry

Lithium-ion cells lose capacity over time and with repeated charge cycles, so runtime will gradually decrease. Performance drops in very cold temperatures, and the pack must be stored at partial charge if unused for long periods. The 3.7 V nominal voltage is fixed by the chemistry; it cannot be increased for longer run-time without a larger cell. Users who need all-day shooting without access to a charger should plan for multiple packs.

Upgrading from a depleted original

This battery replaces an exhausted or lost OEM pack of the same 1.05 Ah rating. The jump is worth it when the original no longer holds a useful charge or when a second battery is required for extended sessions. It does not increase capacity beyond the factory specification, so users who need longer run-time per charge must look for a higher-capacity alternative if one exists for their camcorder.
