Replacement lithium battery

This 11.1V 2600mAh lithium pack is built to match the original specifications for the CEN330, CR330 and CR333 models. It uses an ICR18650 3S1P cell arrangement and includes overcharge, over-discharge, over-voltage and short-circuit protection. The pack measures 70.3 x 35.0 x 35.0mm and weighs 216.0g. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

Suitable models and exclusions

The battery fits devices that require the CEN330, CR330 or CR333 part numbers and the ICR18650 3S1P configuration. Buyers whose equipment uses a different voltage, capacity or cell layout should look elsewhere. It is not intended for devices that need a higher watt-hour rating or a different physical form factor.

Deciding specification

The critical value is the 11.1V 2600mAh rating, which delivers 28.86Wh of energy. If the original battery label shows the same voltage and capacity, this pack will function as a direct replacement. A mismatch in either figure means the part will not work correctly.

Questions about this item

How do I install the Estry CEN330 11.1V 2600mAh battery and what step is often missed?

Power off the device, open the battery compartment, disconnect the old pack, connect the new ICR18650 3S1P connector with correct polarity, secure the pack measuring 70.3 x 35.0 x 35.0mm, and close the cover. The step often missed is verifying the connector orientation before applying force.

What maintenance or replacement will the Estry CEN330 28.86Wh pack need later?

Lithium packs like this 11.1V 2600mAh unit gradually lose capacity over hundreds of charge cycles. No user maintenance is required; when run-time drops below your needs, replace the entire pack with another compatible CEN330, CR330 or CR333 model.

What limit appears first during sustained use of the Estry CEN330 216.0g battery?

The built-in protection circuit stops output if voltage falls too low, current exceeds safe levels, or temperature rises beyond the cell limits. In continuous high-drain use the thermal or over-current threshold is typically reached before the 2600mAh capacity is fully depleted.
