3400mAh Replacement Battery for Zebra Printers - High Capacity

In this review we look at the 3400mAh replacement battery designed for Zebra mobile printers. The bottom line: this cell is for users who need a straightforward, high capacity replacement that fits Zebra QLN and ZQ series models and delivers reliable power with modern safety protections. It does one job clearly: replace the original pack with a compatible 7.4V, 3400mAh Li-ion unit that is easy to install and backed by a 12-month warranty.

Key Features

• Wide compatibility: Works with a long list of Zebra devices so you can replace worn packs in QLN220, QLn320, ZQ500 and related models without switching chargers or adapters.
• High capacity: The 3400mAh/25.16Wh rating provides more runtime than many standard replacements, reducing the frequency of swaps during a shift.
• Built-in safety protection: Overcharge, overdischarge, overheat, overcurrent and short circuit protection help safeguard the printer and the battery during everyday use.
• Easy installation: The pack is shaped and sized to match the original, making drop-in replacement straightforward for field technicians and end users.
• Compact form factor: At 73 x 55 x 25mm and about 124g gross weight it keeps the printer balanced and does not add excessive bulk.
• After-sales support: A 12-month warranty and vendor support offer peace of mind if there are compatibility or performance questions.

Who It's For

This replacement battery suits businesses and technicians who service mobile Zebra printers in warehouses, retail floors, delivery routes, or event operations and need a direct substitute for original packs. It is well suited to teams that prefer Li-ion cells with standard protection features and want the convenience of a plug-and-play swap.

Users who require OEM certification, custom power profiles, or extended cycle warranties beyond 12 months should evaluate factory original options or vendor support plans; likewise, if exact runtime under heavy duty constant printing is critical, testing in your workflow is recommended before large purchases.
