Pulsar Battery APS 3 Rechargeable Pack - Long Life Power

In this review the Pulsar Battery APS 3 is presented as a practical power option for owners of compatible thermal optics. The bottom line: it is for users who need a dedicated, rechargeable power source for Axion thermal monoculars or Thermion riflescopes and value long run time and a quick recharge cycle. The single biggest reason to buy is straightforward: reliable, extended battery life that avoids disposable cells and minimizes downtime in the field.

Key Features

• Rechargeable Lithium-Ion: The APS 3 uses a rechargeable lithium-ion chemistry to replace disposable batteries and reduce ongoing cost and waste.
• Extended Battery Life: With a 3.6 V charge voltage, the pack delivers up to 4 hours in Axion thermal monoculars and up to 8 hours in Thermion riflescopes, which stretches a single outing without swapping packs.
• Quick Full Charge: The battery reaches a full charge in about 3.5 hours, so users can top up between sessions and return to the field quickly.
• Device Compatibility: The APS 3 is designed to fit the Axion Thermal Monocular and Thermion Thermal Riflescope, ensuring a snug, manufacturer-intended connection.
• Charge Indicator: A built-in charge indicator helps monitor remaining power so operators can plan battery changes before critical moments.

Who It's For

The Pulsar Battery APS 3 is ideal for hunters, thermal imaging enthusiasts, and professionals who own an Axion or Thermion device and want a purpose-built rechargeable pack that matches manufacturer specifications. It is especially useful for users who prefer longer single-session runtimes-Thermion users will see the greatest benefit in total hours.

This battery is not for people who need a multi-device universal battery or those seeking an aftermarket pack for devices outside the stated compatibility. If you do not own an Axion or Thermion or need a battery with alternative voltages, look for a different power solution.
