Company Profile

Product Description:

Our 3.7V 6000mAh Durable Speaker Battery Replacement (Model: GSP1029102A 320SL) is designed to bring it back to peak performance.

Unlike generic batteries that prioritize low cost over longevity, this replacement is engineered with durability at its core, making it ideal for users who rely on their JBL Charge 3 2016 for frequent, long-term use.

At its foundation, this battery features a 3.7V nominal voltage—a precise match to the original JBL Charge 3 2016 battery. This ensures seamless integration with the speaker’s power management system, eliminating risks of audio distortion, unexpected shutdowns, or damage to internal circuits that often come with voltage-mismatched batteries.

Paired with a 6000mAh high-density lithium cell, it delivers a runtime of up to 8.5 hours (tested at 50% volume with a mix of music genres)—enough to power a full day of beach outings, a 3-hour backyard party, or multiple evening relaxation sessions without hunting for a power outlet.

Competitive Advantage:

Ⅰ.Durable Construction for Long-Term Use

Most generic replacement batteries use thin, non-protective casings and low-grade cells that fail quickly—they may crack if dropped, lose capacity in extreme temperatures, or stop working entirely after a few months. 

Ⅱ.Precise Compatibility with JBL Charge 3 2016

“Universal” speaker batteries often have mismatched sizes or connectors, forcing users to modify their JBL Charge 3 2016 (e.g., sanding the battery compartment, cutting wires) to make the battery fit. These modifications void the speaker’s warranty and risk damaging its internal components.

Ⅲ.True 6000mAh Capacity

Many cheap replacement batteries claim to have 6000mAh capacity but actually deliver 4000-4500mAh (tested via third-party tools), leading to shorter runtime than expected. Our GSP1029102A 320SL battery uses a genuine 6000mAh lithium cell—we verify capacity with professional equipment before shipping, ensuring it lives up to the label.

Ⅳ.User-Friendly Installation

Some replacement batteries require soldering, wire stripping, or the use of specialty tools—skills most casual users don’t have. Our GSP1029102A 320SL battery is a tool-free, plug-and-play replacement. The connector matches the JBL Charge 3 2016’s port exactly, and the battery fits the compartment without gaps.
