Nickel-Zinc Chemistry and Charge Limits

Nickel-zinc chemistry provides a nominal 3.6 volts and 5.40 watt-hours in this form factor. The supplier advises two to three full charge and discharge cycles before the cell reaches its best performance. Storage above 60 degrees Celsius or 140 degrees Fahrenheit is not recommended, and the battery must not be disassembled, exposed to fire or immersed in water.

Upgrade from Worn Original Cells

This unit replaces a depleted original battery in compatible Summer baby monitors, restoring the runtime the device had when new. It is not suited for devices that require a different voltage, capacity or physical size, nor for applications needing higher energy density than nickel-zinc chemistry provides. The ISO9001, RoHS and CE certifications cover safety and environmental compliance.

Questions about this item

Which FYIOGXG 1500mAh 3.6V Nickel-Zinc battery fits my Summer baby monitor model?

This replacement battery matches Summer part numbers 285650A, 28650, 29000, 29003, 29003A, 29030, 29040, 29500, 29600, 29630, 29890 and 36004. Verify your original battery part number against this list before ordering.

What does the 1500mAh / 5.40Wh rating mean for daily use in my monitor?

The 1500mAh capacity at 3.6V delivers 5.40Wh of energy. Runtime depends on your monitor's actual current draw; a lower draw extends operating time between charges. Expect full performance after two to three complete charge cycles.

Does the nickel-zinc chemistry require a specific charger or voltage limit?

The battery operates at 3.6V nominal and includes built-in overcharge, over-discharge, over-voltage and short-circuit protection. Use only the charger supplied with your Summer monitor; avoid low-quality third-party adapters to preserve battery life.
