Battery Replacement for Motorola XTS5000 & XTS3000 - Long Life 7.5V

In this review the focus is on a direct replacement battery intended for Motorola two-way radios such as the XTS5000 and XTS3000 families. The bottom line: this pack is for users who need a higher-capacity, field-replaceable power source that fits a long list of legacy radio models. The single biggest reason to consider it is the substantially higher stated capacity and broad compatibility with OEM part numbers, making it a practical swap for radios used in municipal, security, or industrial environments.

Key Features

• High capacity: The 3600 mAH rating provides extended run time compared with many stock packs, reducing the need for mid-shift charging.
• Broad compatibility: It explicitly replaces many OEM part numbers including NNTN4435B and 587-5100-470, which simplifies sourcing for mixed fleets.
• Multiple radio families supported: Works with Motorola XTS5000, XTS3000, XTS3500 and several TETRA and EF-Johnson models, making it useful for organizations with varied hardware.
• Ni-MH chemistry: The Ni-MH construction offers a reliable rechargeable option that is familiar to field technicians and service shops.
• Made in Japan components: The listing highlights Japanese manufacturing for the cells, which is often associated with consistent capacity and cycle life.

Who It's For

This replacement battery is aimed at professional users who operate Motorola XTS-series radios or compatible EF-Johnson and TETRA handsets and need dependable run time during long shifts. It is also a good fit for maintenance teams managing fleets where matching OEM part numbers is important for inventory control.

It is not the best choice for casual, occasional users who rarely drain a battery or for radios that require a different voltage or connector. Buyers seeking lithium-based cells or the absolute lightest, smallest pack should look elsewhere.

Pros & Cons

Pros

• Higher 3600 mAH capacity translates to noticeably longer on-air time between charges.
• Direct compatibility with many OEM numbers simplifies replacements across mixed radio fleets.
• Ni-MH chemistry and Japanese-made cells suggest predictable charging behavior and reasonable cycle life.
• Fits a wide range of Motorola XTS and related models, reducing stocking of multiple part types.

Cons

• The pack is Ni-MH and heavier than modern Li-ion options, so weight and energy density are modest compared with newer chemistries.
• Documentation on warranty and exact manufacturing lot details is not provided in the product text, so buyers should confirm return policies before purchase.
