Strong Power 3.7v 2000mAh Lithium Battery Replacement  for JBL Flip2 Bluetooth Speakers

Specifications

Company Profile

Product description

Our Strong Power 3.7V 2000mAh Lithium Battery Replacement is exactly what you need to reignite its performance. Designed as a dedicated upgrade for the JBL Flip2, this battery isn’t just a basic replacement—it’s engineered to deliver “strong power” in every use scenario, matching the speaker’s original power architecture while boosting runtime and stability.

The built-in protection circuit guards against overcharging, overdischarging, short circuits, and overheating—eliminating the risk of bulging, leaking, or fire. The outer casing is made of scratch-resistant, flame-retardant ABS plastic, which can withstand minor impacts (like the speaker being knocked off a table) and extreme temperatures (from 32°F to 104°F)—perfect for outdoor use where the Flip2 is often exposed to rough handling.

Every battery undergoes a 6-step quality control process before shipping: power output testing (to verify “strong power” performance), capacity validation (ensuring full 2000mAh output), fitment checks on real JBL Flip2 speakers, safety certification verification, durability simulation (100+ hours of continuous use), and storage performance testing (low self-discharge rate).

This rigorous process guarantees that every battery delivers consistent, reliable strong power—whether you’re using it for personal enjoyment, professional repairs, or bulk resale.

Competitive Advantages

I.Strong Power Optimization for JBL Flip2 – More Than Basic Replacement

Most replacement batteries for the Flip2 only offer “basic power,” but we’ve optimized ours for “strong power” specifically. The high-density lithium-ion cell with low internal resistance delivers instantaneous current output, ensuring the Flip2’s bass is punchy, sound is loud, and performance matches its original design. 

II.Exact Fit & Plug-and-Play – No Hassle, No Risk

We’ve engineered this battery to the exact specifications of the JBL Flip2’s original cell: same dimensions, same connector, same voltage. No modifications, no wire splicing, no forcing the battery into the compartment

Just a 5-minute installation. This eliminates the risk of damaging your speaker (a common issue with ill-fitting generic batteries) and ensures seamless compatibility from the first use.

III.True 2000mAh Capacity – No Inflated Claims

Many competitors label their batteries “2000mAh” but deliver only 1500-1800mAh, leading to shorter runtime and disappointed customers. We test every battery with professional equipment to confirm full 2000mAh capacity.

You get the runtime you’re promised, no tricks or shortcuts. Our battery’s high-grade cell also ensures slow capacity fading: after 300 charge cycles, it still retains over 75% of its original capacity.
