 Company Profile

Product Description

Our High-Capacity 3.7V 3000mAh Lithium Polymer Battery Replacement is the ultimate solution to revive its performance. Specifically engineered for the JBL Flip 3, this battery isn’t just a generic replacement—it leverages the advantages of lithium polymer technology to deliver unmatched capacity, safety, and compatibility, all while staying true to the speaker’s original design.

Let’s break down the game-changing specs: a nominal voltage of 3.7V (100% compatible with the JBL Flip 3’s power system) and a true 3000mAh high-density lithium polymer cell. Unlike traditional lithium-ion batteries or cheap generic cells that overpromise and underdeliver, our li-polymer battery offers higher energy density, meaning it packs more power into a slim, lightweight form factor.

This translates to 6-7 hours of continuous playback at 50% volume (enough for a full day of hiking, a backyard BBQ, or a long road trip) and 3-4 hours at maximum volume—double the runtime of many low-quality replacements and even outperforming the Flip 3’s original battery (which typically degrade to 1500-2000mAh after 1-2 years of use).

Designed for both personal use and professional applications, this high-capacity li-polymer battery is the perfect way to extend the life of your JBL Flip 3. It’s not just a battery—it’s a reliable, long-lasting upgrade that brings your favorite speaker back to its full potential.

Application

I.Personal & Daily Use

•All-Day Outdoor Adventures: Take your JBL Flip 3 on hiking trips, beach days, or camping weekends—this 3000mAh high-capacity battery keeps the music playing from sunrise to sunset.

•Home & Family Gatherings: Host a movie night, game day, or family dinner with the Flip 3 as your soundtrack. The long runtime means you can place the speaker anywhere in the house (no need to stick it near an outlet) and enjoy uninterrupted music for the entire gathering—no awkward pauses to recharge.

•Fitness & Active Lifestyles: Use the Flip 3 for your daily workout, yoga session, or morning run. The 3000mAh capacity lasts through 2-3 intense workouts (1.5-2 hours each) without needing a charge, and the li-polymer’s lightweight design keeps the speaker portable—no extra bulk in your gym bag.

II.Business & Professional Use

•Speaker Repair Shops: For repair shops specializing in JBL devices, this high-capacity li-polymer battery is a top-tier stock item. Its exact fit for the Flip 3 eliminates compatibility issues, and the “3000mAh high-capacity” selling point makes repairs more attractive to customers wanting to upgrade their speaker’s runtime.

•Used Speaker Refurbishment: Sellers of pre-owned JBL Flip 3 speakers can drastically increase product value by installing this battery. Market the speaker as “upgraded with 3000mAh high-capacity battery” to stand out from competitors selling units with old, worn-out batteries—and command a higher price.

•Small Business Background Music: Cafés, bookstores, boutique shops, or yoga studios using JBL Flip 3 for ambient music will benefit from this battery. It runs for 6-7 hours on a single charge, covering a full business day (9 AM to 5 PM) with moderate use—no need to interrupt music to recharge.

Competitive Advantages

•True 3000mAh High-Capacity Li-Polymer Cell – No Inflated Claims

Most replacement batteries for JBL Flip 3 claim to be “3000mAh” but only deliver 2000-2500mAh, leading to disappointing runtime. Our battery uses a high-density lithium polymer cell and undergoes strict capacity verification—we guarantee it’s a true 3000mAh. The li-polymer technology also offers 15-20% higher energy density than traditional lithium-ion, meaning more power in the same size. 

•Exact Fit for JBL Flip 3 – No Modifications, No Risks

Generic batteries often require trimming the case, splicing wires, or forcing the battery into the compartment—risking damage to your Flip 3’s internal components.

Our battery is engineered to the exact specifications of the Flip 3’s original battery: same dimensions (precision-machined to 0.1mm tolerance), same connector type, and same plug-and-play interface. It slides into the battery compartment seamlessly, no tools or modifications needed. This eliminates the risk of short circuits, poor connectivity, or speaker damage—common issues with ill-fitting batteries.

•Lithium Polymer Exclusive Advantages – Safer & More Durable

Unlike lithium-ion batteries with rigid metal casings, our li-polymer battery uses a flexible, leak-proof packaging. It’s resistant to bulging (a major issue with old lithium-ion cells) and won’t leak harmful chemicals if accidentally dropped.

It also has zero memory effect—charge it at any time without reducing capacity—and a lower self-discharge rate (loses only 5% capacity per month in storage, vs. 10-15% for lithium-ion). For outdoor use, this means more reliable performance and longer shelf life.

•Longer Cycle Life – Cost-Effective in the Long Run

Cheap replacement batteries degrade after 150-200 charge cycles, forcing you to buy a new one every year. Our high-capacity li-polymer battery lasts 400+ charge cycles, retaining over 80% of its original capacity even after 2-3 years of regular use.

•Optimized for JBL Flip 3’s Power Demands – Better Than OEM

The JBL Flip 3 is known for its balanced sound and moderate bass—our battery is tuned to match its power needs exactly. The 3.7V voltage delivers stable current to the speaker’s amplifier, ensuring clear sound at low volumes and punchy bass at high volumes (no distortion or volume drops).
