7.5V 3800mAh NiMh Battery Replacement for XTS3000 - Reliable Power

In this review the focus is on a direct replacement battery for Motorola-style portable radios used in demanding work environments. The 7.5V 3800mAh NiMh pack is presented as a straightforward option for users who need a higher-capacity, drop-in replacement for models listed like the XTS3000, XTS3500 and XTS5000. The bottom line: this battery is for anyone who needs dependable runtime and compatibility with NTN8923/NTN8923AR/RNN4006 series radios, and the single biggest reason to buy is the increased 3800mAh capacity that extends on-shift use without altering existing chargers or radio ergonomics.

Key Features

• 7.5V NiMh chemistry: Offers a familiar, rechargeable chemistry that is widely compatible with legacy two-way radio designs and tolerates heavy duty use in the field.
• 3800mAh capacity: Provides longer runtime than many stock packs so teams can complete longer shifts between charges.
• Direct replacement fit: Intended to replace NTN8923 and similar part numbers so users can swap batteries without modifying radios or accessories.
• Models supported: Specified for XTS3000, XTS3500, XTS4250 and XTS5000 families making it useful across multiple radio models in a fleet.
• Two-way radio focus: Designed specifically for portable radios rather than general-purpose battery use, simplifying selection for radio users.

Who It's For

This battery is well suited to professional users running Motorola-compatible radios in security, event staff, construction, or facilities teams who need reliable, extended runtime and a straightforward replacement process. It is a good fit where users prefer NiMh chemistry over newer lithium options due to charger compatibility or existing inventory.

Users who should look elsewhere include those who require the absolute lightest weight or the fastest charge times available from modern lithium packs, or who need manufacturer-certified OEM batteries for warranty reasons. Also not ideal if your radio explicitly requires a different voltage or connector type.

Pros & Cons

Pros

• Higher 3800mAh capacity yields noticeably longer runtime compared with many standard packs.
• Made as a direct replacement for NTN8923/NTN8923AR/RNN4006 series, so fit and function are straightforward.
• Compatible with multiple XTS series models, reducing the need for different stock for mixed fleets.

Cons

• NiMh chemistry is heavier and charges slower than modern lithium alternatives, which may matter for weight-sensitive use.
• Not an OEM-branded pack for some radio manufacturers, which could be a consideration for strict warranty policies.
