Specifications

Company Profile

Product Description:

Our Factory Price 3.7V 22.2Wh (6000mAh) Lithium Batteries (Models: GSP1029102A & JML330SL) are exactly what you need. We’re cutting out middlemen, so you get factory-direct prices without sacrificing quality—perfect for anyone who wants a reliable battery for their JBL Charge 3 Bluetooth Speaker, whether it’s for personal use or bulk repairs.

First, let’s talk specs—this isn’t some “fake 6000mAh” battery. It’s a real 6000mAh (22.2Wh) high-density lithium cell with a steady 3.7V output, matching the JBL Charge 3’s original power needs exactly.

What does that mean for you? No more sudden volume drops when playing bass-heavy songs, no random shutdowns during outdoor trips, and a full 8-9 hours of playback at 50% volume—enough to last a whole day at the beach, a backyard BBQ, or even a long road trip.

Every battery goes through 4 checks before we ship it: we test the voltage to make sure it’s stable, verify the capacity is really 6000mAh, check that it fits the JBL Charge 3 perfectly, and run a durability test. So you’re getting a factory-quality battery at a price that’s hard to beat—no markups, no tricks, just a great deal for your JBL Charge 3.

Application

Ⅰ.Personal & Daily Use

•Outdoor Fun: Take your JBL Charge 3 to the beach, campground, or park—this battery’s 6000mAh capacity lasts all day. Play music while you swim, hike, or have a picnic, and you won’t have to hunt for a power outlet. 

•Home Gatherings: Host a small party, movie night, or game night with your Charge 3. The battery keeps the speaker running for hours, so you can put the speaker anywhere (no need to plug it near a wall) and keep the vibe going—no awkward silences from a dead battery.

•Everyday Listening: Use your Charge 3 in the kitchen while cooking, in the bedroom while relaxing, or in the garage while working. The long battery life means you only need to charge it once a week (if you use it a few hours a day), so it’s always ready when you want music.

II. Business & Professional Use

•Speaker Repair Shops: If you fix JBL Charge 3 speakers, this factory-price battery is a no-brainer. It’s cheap enough to buy in bulk, and the consistent quality means fewer returns from customers. You can offer affordable repairs and still make a profit—win-win.

•Small Businesses: Cafés, gyms, or small retail stores that use JBL Charge 3 for background music can stock this battery. It’s durable, so you don’t have to replace it often, and the low price cuts down on your maintenance costs. Keep a spare, and you’ll never have silent gaps in your store.

•Second-Hand Speaker Sellers: If you sell used JBL Charge 3 speakers, installing this battery makes your products more appealing. Customers hate buying used speakers with bad batteries—with this 6000mAh one, you can market the speaker as “like new” and charge a better price.

Competitive Advantage:

Ⅰ.Factory Direct Price

Most replacement batteries for JBL Charge 3 are sold through retailers, who add 20-50% markup to make a profit. Our battery is sold directly from the factory—so you skip the store, the distributor, and all the extra costs.

You get the same quality as name-brand batteries but at a price that’s 30-40% lower. For example, a retail 6000mAh battery for Charge 3 might cost $25, but ours is factory-priced at under $15. If you buy in bulk, the price gets even better—perfect for businesses or anyone who needs multiple batteries.

II.Real 6000mAh Capacity

Lots of cheap batteries claim to be 6000mAh, but when you test them, they’re only 4000-4500mAh. That means shorter runtime, more frequent charging, and frustration. Our battery is tested before shipping to make sure it’s a real 6000mAh (22.2Wh)—you get the full runtime you expect, no tricks. Whether you’re using it for 8 hours outdoors or 5 hours at home, it won’t die on you early like those fake-capacity batteries.

III.Exact Fit for JBL Charge 3 = No Modifications

Universal speaker batteries say they “fit all JBL models,” but they’re never a perfect fit for the Charge 3. You might have to sand down the battery compartment, cut wires to match the connector, or tape the battery in place—all of which can damage your speaker or void its warranty. 

V.Durable Build

Flimsy batteries have thin plastic cases that crack if you drop them, and their cells die fast—you’ll be replacing them every 6-12 months. Our battery has a thick, impact-resistant case that can handle minor drops and scratches. Inside, the lithium cell uses high-quality materials that last 300+ charge cycles (with 80% capacity left)—that’s 2-3 years of regular use. You won’t have to keep buying new batteries, saving you money in the long run.

IV.Fast Charging

Some replacement batteries take 4-5 hours to fully charge—annoying if you need to use your speaker fast. Our battery charges quickly: with a standard JBL charger, it hits 80% in 2 hours and full capacity in 3.5 hours. If you’re in a hurry (like before a party or trip), you can top it up fast and go—no more waiting around for a dead battery to charge.
