iOptron Replacement Lithium-Ion Battery for AZ Mount Pro and HAZ46/71 Mounts (#8959)
Reliable onboard power to keep your mount running all night.

The iOptron #8959 replacement battery is a custom-fit lithium-ion power pack designed to restore or extend the battery life of your AZ Mount Pro, HAZ46, or HAZ71 mounts. Whether you're replacing a worn-out original or stocking a spare for extended field sessions, this rechargeable battery keeps your system lightweight, self-contained, and ready for uninterrupted tracking.

Engineered for Field Use

This compact battery uses high-efficiency lithium-ion cells to provide stable 11.1V output, peaking at 12.6V when fully charged. It’s designed specifically to integrate within the mount’s internal power compartment—so you’ll never need to strap on an external pack or run trailing power cables across your setup.

With a 4400mAh capacity, it can deliver several hours of operation under normal observing loads. A built-in protection circuit guards against overcharging and deep discharge, giving you reliable power session after session.

Lightweight and Mount-Specific

Weighing just over 10 ounces, the #8959 battery won’t affect your mount’s balance or portability. It installs easily and is shaped to match the internal battery compartment of the AZ Mount Pro and HAZ series models, so there’s no guesswork or loose fit.

This battery is intended for use with a proper charger rated for 12.6V lithium-ion packs. Charging below freezing or using the wrong voltage can shorten its lifespan, so be sure to follow standard lithium-ion battery safety practices.
