Battery replacement for Audio Pro speakers

This Estry lithium pack replaces the original TF18650-2200-1S4PB cell used in Audio Pro Addon T3, T9 and T10 models. It delivers a nominal 14.8 V and a rated capacity of 3400 mAh, matching the factory voltage and energy specification. The pack measures 69.1 x 37.8 x 37.1 mm and weighs 258.7 g, fitting the existing battery compartment without modification.

Suitable for owners of listed Audio Pro models

Buyers with an Addon T3, T9 or T10 speaker needing a direct-fit replacement will find the correct connector layout and form factor here. Users whose speaker requires a different voltage, a higher capacity than 3400 mAh, or a different physical footprint should look at other options. The pack is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards for safety and transport compliance.

Deciding specification is the 14.8 V 3400 mAh rating

This voltage and capacity combination determines whether the pack powers your specific Addon model for the intended runtime. Verify that your original battery carries the part number TF18650-2200-1S4PB and the same 14.8 V rating before ordering. The 50.32 Wh energy rating and built-in overcharge, over-discharge, over-voltage and short-circuit protection complete the safety profile.
