Replacement Battery for Yeacomm P21 4G

This replacement cell is built for the Yeacomm P21 4G hotspot and matches the original Z2200B part number. It delivers a capacity of 3350 mAh at 3.7 volts for 12.40 Wh of energy. The pack includes a fully decoded chip so the device recognises it like the factory unit. It suits users who need a direct swap for a worn or lost original battery.

Certified Safety and Thermal Behaviour

The cell carries ISO9001, RoHS and CE certifications confirming baseline safety and environmental compliance. Built-in protection guards against overcharge, over-discharge, over-voltage and short-circuit events during normal operation. The lithium chemistry runs at the standard 3.7 V nominal voltage without special cooling requirements. No noise or active thermal management is involved with this passive component.

Protected Packaging and Support Terms

The unit ships inside shock-absorbing foam to prevent transit damage to the cell. Buyers receive a twelve-month warranty period and a thirty-day money-back window from the supplier. Email support is offered with a twenty-four-hour response target for installation questions. There are no bundled tools, cables or software included with this battery.

Questions about this item

How do I install the 3350 mAh battery into my Yeacomm P21 4G without damaging the decoded chip?

Power off the hotspot, remove the rear cover, disconnect the old pack, align the new Z2200B connector and press gently until it clicks, then refit the cover before powering on.

What maintenance will the 3.7 V lithium-ion cell need after months of daily charging?

No scheduled maintenance is required; store at roughly half charge if unused for weeks, avoid extreme heat, and replace the pack once runtime drops noticeably below the rated 12.40 Wh.

Which limit appears first during continuous 4G hotspot use — thermal throttle or capacity drop?

The protection circuit will cut output if temperature or voltage exceeds safe thresholds, so thermal limits trigger before any permanent capacity loss.
