Replacement Kenwood KNB-55L Battery 2 Pack - 2000mAh Li-Ion

In this review the reviewer looks at the 2 Pack replacement for Kenwood KNB-55L batteries from Upstart Battery and recommends it for users who need affordable, same-spec power for Kenwood-compatible two-way radios. The bottom line is straightforward: this is a practical, cost-conscious swap for the KNB-55L / KNB-35L form factor that restores runtime with a rated 2000mAh capacity. It is not an OEM cell, so buyers who want manufacturer-backed warranties should note Upstart Battery provides the warranty here, not the original radio maker.

Key Features

• Replacement compatibility: Designed to fit radios that accept Kenwood KNB-55L and KNB-35L style batteries so radios regain portable runtime without modifications.
• Dual quantity: Two batteries are included, giving immediate backup power for longer shifts or a spare to keep radios in use while one charges.
• Rated capacity: Each battery is specified at 2000mAh, offering a predictable runtime comparable to the original spec for routine radio use.
• 7.4V Li-Ion chemistry: The 7.4V lithium-ion construction keeps weight reasonable while delivering stable voltage for typical two-way radio operation.
• Third-party warranty: Warranty coverage is provided by Upstart Battery, which is the point of contact for any issues rather than the original manufacturer.

Who It's For

This replacement battery pack suits commercial users, event staff, hobbyists, and anyone running multiple shifts who needs a reliable, cost-effective spare or replacement for Kenwood KNB-55L/KNB-35L compatible radios. The two-pack format is especially useful where continuous operation is required and swapping batteries is part of the workflow.

It is not aimed at buyers who insist on OEM-labelled parts or who require the original manufacturers warranty. If official manufacturer support or branding is essential, those buyers should seek an OEM battery instead.
