Cameron & Co DS-CS-PLC278SL 3.6V 1000mAh laptop battery

SKU CH-W4FV-ATNZ2

Primary lithium-manganese dioxide battery supplying 3.6 V and 1000 mAh for Toshiba PLC modules

  • Product typeBattery
  • Compatible with Toshiba ER3V devices
  • 6V 1000mAh primary lithium manganese dioxide power
  • Compact 29.85 x 16.93 x 14.60 mm form factor
  • Non-rechargeable design for reliable single-use operation
  • Black connector ensures correct polarity alignment

Compatible replacement for Toshiba ER3V

This Cameron & Co DS-CS-PLC278SL primary battery replaces the Toshiba ER3V unit in compatible devices. It delivers a 3.6 V nominal voltage and a 1000 mAh capacity using Li-MnO2 chemistry. The black housing measures 29.85 x 16.93 x 14.60 mm and features a brown colour connector. It is a non-rechargeable cell supplied new and 100% OEM compatible.

Upgrade from depleted ER3V cells

The jump is worth it when the original ER3V battery no longer holds sufficient charge for memory backup or real-time clock functions. This primary cell restores the specified 3.60 Wh energy rating without requiring recharging circuitry. It suits maintenance cycles where a fresh, factory-fresh Li-MnO2 unit is preferred over recharged alternatives.

Capacity headroom for low-drain backup

The 1000 mAh rating comfortably handles typical CMOS memory and RTC loads for extended periods. It runs out when the cumulative drain exceeds the 3.60 Wh capacity or when the Li-MnO2 chemistry reaches end of life. This single cell is not designed for high-current or cyclic recharge applications.

Questions about this item

Will the 29.85 x 16.93 x 14.60 mm dimensions fit my Toshiba PLC slot?

Yes, the cell measures 29.85 mm long, 16.93 mm wide and 14.60 mm thick, matching the original ER3V form factor for direct replacement.

How do I install the battery and which step is often missed?

Insert the brown connector into the board header with the polarity notch aligned, then press until the latch clicks; the step often missed is verifying the notch orientation before applying force.

When will the 1000 mAh Li-MnO2 cell need replacement?

As a primary non-rechargeable Li-MnO2 unit, it cannot be recharged; replace it when the system clock or CMOS settings start to drift, typically after several years of continuous use.
