Nickel-zinc chemistry thermals and runtime

The nickel-zinc cells operate at the specified 14.40 volts and 37.44 watt-hours, providing a direct swap for the original pack. Normal charging and discharging temperatures follow the chemistry's standard behaviour. The battery weighs 200.0 grams and measures 70.40 by 37.10 by 37.10 millimetres, matching the original form factor. It is not for users who need a higher-capacity pack or a different cell chemistry.

Ready-to-install drop-in pack

The battery arrives as a complete pack with the correct wiring and connector for the listed models, so no soldering or adapter is required. A new pack reaches its best performance after a few charge cycles. It is not for buyers who want a bare cell kit or who need a charger included in the box.

Questions about this item

How do I install the 14.4V 2600mAh battery in my Eufy RoboVac LR30 Hybrid+ and what step is often missed?

Power off the vacuum, remove the battery cover screws, disconnect the old pack, connect the new CMICR18650F9M-4S1P pack ensuring the plug seats fully, refit the cover and charge fully before first use.

What maintenance or replacement will the FYIOGXG 14.4V 2600mAh pack need over time?

The Li-ion cells gradually lose capacity; when run-time drops noticeably the pack should be replaced with another 14.4V 2600mAh unit matching part numbers CMICR18650F9M-4S1P or T2996011.

What limit appears first during sustained cleaning with this 37.44Wh battery?

The 2600mAh capacity determines run-time; under continuous high-power suction the pack will deplete before thermal limits are reached, requiring a recharge cycle.
