Pulsar Battery Compatibility Guide: Which Battery Fits Your Optic?
Bruce NolanShare
Choosing the correct replacement battery for a Pulsar thermal or digital night vision optic can be confusing because several battery families look similar but are not interchangeable. This guide matches the Pulsar APS-5, APS-5T, APS-2, APS-3, and LPS-7i with the compatible optics currently supported by each battery family.
Important: Always confirm the exact optic model and generation before ordering. A battery used by one generation of a Pulsar product line may not fit another. Published operating time is approximate and varies with temperature, Wi-Fi, recording, display brightness, laser rangefinder use, and battery condition.
Pulsar Battery Compatibility at a Glance
| Battery | Capacity | Typical Runtime | Compatible Product Families |
|---|---|---|---|
| APS-5 | 4,900 mAh | Approximately 4–6 hours | Thermion 3, Symbion, Oryx, Axion 2, Proton |
| APS-5T | 4,900 mAh | Approximately 4–6 hours | Talion XQ35 Pro and Talion XG35 |
| APS-2 | 2,000 mAh | Approximately 3.5–5 hours | Thermion 1, Thermion 2, Digex and Digex-X |
| APS-3 | 3,200 mAh | Approximately 4–5 hours | Axion XM, Thermion 1, Thermion 2, Digex, Merger |

APS-5T Battery Compatibility
The Pulsar APS-5T battery is a 4,900 mAh rechargeable lithium-ion battery designed specifically for Pulsar Talion thermal scopes. It provides approximately 4–6 hours of runtime, depending on operating conditions. Although the APS-5 and APS-5T share the same listed capacity, they are different battery formats and should not be treated as interchangeable.

APS-2 Battery Compatibility
The Pulsar APS-2 battery is a 2,000 mAh removable battery commonly used in Thermion and Digex optics. It provides approximately 3.5–5 hours of runtime. On compatible Thermion models, the removable APS battery works alongside the optic’s internal battery system.
APS-2 Compatible Pulsar Optics
- Thermion 1 thermal scopes
- Thermion 2 thermal scopes, including:
- Digex and Digex-X digital night vision scopes
APS-3 Battery Compatibility
The Pulsar APS-3 battery increases capacity to 3,200 mAh and provides approximately 4–5 hours of runtime. It supports several earlier Pulsar platforms as well as compatible Merger thermal binoculars.
APS-3 Compatible Pulsar Optics
- Axion XM thermal monoculars
- Thermion 1 thermal scopes
- Thermion 2 thermal scopes
- Digex digital night vision scopes
- Pulsar Merger LRF XP35 640 Thermal Binocular
- Pulsar Merger LRF XT50 1280 Thermal Binocular
The Pulsar APS-2/APS-3 Battery Charger can charge both battery sizes.
LPS-7i Battery Compatibility
The Pulsar LPS-7i battery is a 6,400 mAh rechargeable lithium-ion pack with USB Power Delivery fast charging and wireless charging support. Its listed runtime is approximately 7–8 hours.

APS-2 vs. APS-3: Can Both Fit a Thermion?
Many Thermion 1 and Thermion 2 models accept either an APS-2 or APS-3 as the removable battery. The APS-2 is smaller and lighter, while the APS-3 offers greater capacity and usually a longer operating time. Compatibility can vary by exact model and generation, so verify the optic’s manual or contact us before ordering.
Pulsar Battery Runtime Tips
- Cold weather can reduce lithium-ion battery runtime.
- Wi-Fi, video recording, high display brightness, and frequent laser rangefinder use increase power consumption.
- Charge batteries before long outings and carry a fully charged spare when practical.
- Use the charger designed for the correct battery family.
- Store batteries partially charged in a cool, dry location when they will not be used for an extended period.
Frequently Asked Questions
Which battery fits the Pulsar Talion XQ35 Pro and Talion XG35?
The Pulsar Talion XQ35 Pro and Pulsar Talion XG35 use the Pulsar APS-5T battery.
Which battery fits the Pulsar Thermion 3 XR60 and XT60?
The Thermion 3 XR60 and XT60 are listed as compatible with the Pulsar APS-5 battery.
Which battery fits Pulsar Thermion 1 and Thermion 2 scopes?
Compatible Thermion 1 and Thermion 2 models use removable APS-2 or APS-3 batteries. Always confirm the exact model because the internal battery arrangement differs by generation.
Which battery fits Pulsar Merger thermal binoculars?
