Direct Replacement Battery

This Estry Ni-MH battery replaces the P-P303PA1B TYPE4 pack in compatible devices. It delivers the original 3.6V and 600mAh specifications in a single pack. The 42.57 x 30.2 x 14.43 mm form factor matches the factory dimensions. Certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Upgrade From Depleted Cells

The jump is worth it when the original pack no longer holds a charge or shows reduced runtime. This unit restores the 2.16Wh energy rating with overcharge, over-discharge, over-voltage and short-circuit protection. Buyers who need a different voltage or a higher capacity pack cannot use this model.

Capacity And Runtime Headroom

The 600mAh capacity handles typical cordless phone or small electronics duty cycles. It weighs 77.4g and fits the existing battery compartment without modification. Devices that draw more current than the pack can supply or require a larger physical size will run out of power or not fit.

Questions about this item

What are the exact dimensions of the Estry P-P303PA1B TYPE4 battery?

The pack measures 42.57 x 30.2 x 14.43 mm and weighs 77.4 g, so verify your device compartment matches these figures before ordering.

How do I install this Ni-MH replacement battery correctly?

Match the connector polarity exactly to the original P-P303PA1B pack, insert the plug firmly until it clicks, then charge fully before first use; reversed polarity is the common error.

When will this 3.6 V 600 mAh Ni-MH pack need replacing?

Expect service life to end when run-time falls sharply or the pack no longer holds a full 2.16 Wh charge; Ni-MH cells degrade gradually with age and cycle count.
