GSP1029102R 310sl Replacement Original Battery 3.7V 6000mAh for JBL Charge 2 Plus & Charge 3 2015 Version Bluetooth Speaker

Specifications

Company Profile

Product Description:

If you own either a JBL Charge 2 Plus or a JBL Charge 3 2015 Version Bluetooth Speaker, and have noticed its battery life fading—like dying after just 2-3 hours of playback, or failing to hold a charge overnight—our GSP1029102R 310sl Replacement Original Battery is the one-stop solution to restore its performance.

Unlike generic batteries that only fit a single model, this battery is engineered to match the exact specifications of both JBL Charge 2 Plus and Charge 3 2015 Version, making it a versatile choice for users with multiple JBL speakers or repair shops handling mixed models.

At the heart of this battery is a 3.7V nominal voltage—identical to the original JBL batteries—which ensures seamless compatibility with the speakers’ power management systems. No more worrying about voltage mismatches that could cause audio distortion or damage internal circuits.

Paired with a 6000mAh high-density lithium cell, it delivers a runtime of up to 9 hours (tested at 50% volume with standard music tracks)—enough to power a full day of outdoor picnics, a 4-hour backyard barbecue, or multiple evening listening sessions without needing a recharge.

Application

I.Personal User Scenarios (Dual-Model Adaptability)

• Multi-Speaker Household Use: If you own both a JBL Charge 2 Plus (for indoor use) and a Charge 3 2015 Version (for outdoor trips), this single battery model works for both. 

• Outdoor Adventure & Travel: Power your JBL Charge 3 2015 Version during hiking, camping, or beach trips—its 6000mAh capacity lasts through a full day of use, even when streaming music from your phone. 

• Daily Indoor Leisure: Use it with the JBL Charge 2 Plus in your living room for background music while working, or in the kitchen while cooking. 

• Emergency Backup: Keep a GSP1029102R 310sl battery in your car or travel bag. If your JBL speaker dies during a road trip or party, you can quickly replace the battery and resume using it—no need to wait for a recharge.

II.Commercial & Professional Scenarios

• Speaker Repair Shops: Handle repairs for both JBL Charge 2 Plus and Charge 3 2015 Version with one battery stock. 

• Small Business Venues: Cafes, gyms, or co-working spaces that use both JBL models for background music can use this battery as a universal replacement.

• Second-Hand Speaker Refurbishment: Sellers of pre-owned JBL Charge 2 Plus/Charge 3 2015 Version can standardize on this battery.

Competitive Advantage:

I.Dual-Model Compatibility (vs. Single-Model Batteries)

• Most replacement batteries for JBL speakers are designed for only one model—for example, a battery that fits Charge 2 Plus won’t work with Charge 3 2015 Version, forcing users to buy two separate batteries if they own both speakers.

• Our GSP1029102R 310sl battery solves this pain point by matching the shared specifications of both models. It fits the battery compartment, connects to the power port, and works with the power management system of both Charge 2 Plus and Charge 3 2015 Version. 

II.Original-Spec Voltage & Capacity (vs. Mismatched Spec Batteries)

• Many cheap replacement batteries claim to be “compatible” but have mismatched voltage (e.g., 3.6V or 3.8V) or inflated capacity (e.g., labeling 6000mAh but actual capacity is 4500mAh). 

• It works in perfect harmony with the speaker’s internal components, delivering consistent runtime and avoiding the risks of spec mismatch. Users get the same performance as an original battery, without the original’s high price tag.

III.Tool-Free Installation & Universal Fit (vs. Modification-Required Batteries)

• Generic batteries often have slightly different sizes or connector positions than original JBL batteries, requiring users to modify their speakers—like sanding down the battery compartment, cutting wires to match the connector, or using tape to secure the battery.
