Replacement battery for PUXING radios

The Estry PX-888 is a 7.4V 1200mAh lithium pack built to match the original PB-72L specification. It fits the PX-888 Plus, PX-UV973, PX-328, PX-728, PX-888K, PX-777 Plus and PX-777 handhelds. Each unit carries ISO9001, RoHS, CE, UN38.3 and MSDS certification. Operators needing a direct swap for depleted stock cells will find the form factor identical.

Thermal behaviour and power delivery

The chemistry includes overcharge, over-discharge, over-voltage and short-circuit protection circuits that limit heat rise during normal transmit cycles. At 8.88Wh the pack delivers consistent voltage across the rated capacity without triggering thermal cut-off. No active cooling is required and the protection logic prevents damage from accidental reverse polarity or prolonged key-down.

Mechanical fit and daily handling

Dimensions are 95.2 by 60.48 by 25.0mm and weight is 151.5g, matching the OEM battery cavity exactly. The latch slides engage the same rails as the factory pack so no shimming or force is needed. Users who need a different voltage, a higher capacity or a connector style other than the native PUXING interface should look elsewhere.

Questions about this item

How do I install the Estry PX-888 battery in my PX-888 Plus radio, and what step do people often miss?

Slide the pack into the battery compartment until the latch clicks, then verify the 7.4V label faces outward; the step often missed is confirming the PB-72L part number matches the radio's sticker before closing the cover.

What maintenance will this 1200mAh lithium pack need over its life?

Recharge before voltage drops below the radio's low-battery alert, store at roughly half charge if unused for weeks, and wipe the gold contacts with a dry cloth if they appear oxidised.

What is the first limit I will hit during a long transmit session with this 8.88Wh pack?

The 1200mAh capacity will deplete first, ending transmission time before the over-discharge protection circuit activates.
