5-Pack UV-5R BL-5L 3800mAh Extended Battery for Baofeng Radios - Long

Our review of the Teseko 5-Pack UV-5R BL-5L 3800mAh Extended Battery finds it useful for anyone who relies on Baofeng handheld radios and needs far longer runtime than the stock cell can provide. The bottom line: this pack doubles typical capacity versus the original 1800 mAh cell and adds safety protections that reduce the worry of over-charge, over-discharge and short circuits. For field operators, hobbyists and emergency preppers who want extended uptime and a more substantial grip on their radio, this replacement battery set delivers consistent, tangible runtime improvements.

Key Features

• Compatibility: Designed to fit Baofeng UV-5R series and related handsets, so it replaces the original battery without adapters.
• Extended Capacity: With 3800 mAh capacity per pack, it offers roughly twice the runtime of the factory 1800 mAh battery for longer on-air periods.
• Safety Protection: Built-in safeguards protect against over-charge, over-discharge, over-heat, over-current and short circuits for safer daily use.
• No Memory Effect: The chemistry allows top-ups at any time without losing usable capacity, so you can charge whenever convenient.
• Improved Handling: The larger pack increases the radio's bulk slightly, making the handset easier to hold and manipulate during extended use.
• After-sales Support: A 90-day satisfaction promise means the seller will provide customer service if the product does not meet expectations.

Who It's For

These batteries are best for amateur radio operators, outdoor workers, security teams and emergency preparedness users who need significantly longer runtime from Baofeng UV-5R style radios. The extra capacity is especially helpful for long shifts, field operations or multi-day events where charging opportunities are limited.

Users who prefer the smallest possible radio footprint or who require factory-original battery dimensions for a specific accessory should consider alternatives; the extended pack increases size and weight compared with the standard 1800 mAh cell.
