Buyer’s Guide

The Aimpoint AA battery is a specialized power source for compact red dot sights and other small electronics. Understanding its characteristics and proper use will help you select the right battery for your equipment.

Technical Specifications

Aimpoint AA batteries feature a nominal voltage of 1.5 volts and provide approximately 400 milliampere-hours (mAh) of capacity. They operate reliably between -40° and +70°C (-40° and +158°F) temperatures. The batteries meet strict military and aerospace standards for performance and durability.

Performance Characteristics

These batteries offer consistent voltage during discharge, maintaining over 90% capacity at both full and half capacity levels. They provide reliable operation in cold weather due to their high energy density and low self-discharge rate. The AA design allows for easy installation in most compact weapon sights and devices.

Environmental Considerations

Aimpoint AA batteries contain no mercury and are classified as alkaline batteries. They should be recycled or disposed of according to local hazardous waste regulations. The low self-discharge rate means they retain 70-80% of their charge after one year of storage.

Operational Recommendations

Store batteries at room temperature when not in use to extend their service life. Avoid mixing new and old batteries, and do not recharge these primary cells. Use a fresh battery with each sight setup to ensure optimal performance. Regularly check battery levels and replace when the red dot brightness noticeably decreases.

FAQ

What is an Aimpoint AA battery?

The Aimpoint AA battery is a specialized power source designed for Aimpoint’s red dot sights and other compatible devices. Unlike standard AA batteries, it features advanced electronics that enhance the sight’s performance and longevity.

These batteries are not interchangeable with standard AA batteries and require specific charging equipment or proprietary chargers.

How long does an Aimpoint AA battery last?

When properly maintained, an Aimpoint AA battery can last up to 2 years with regular use. This longevity is due to its advanced charging profile that prevents overcharging and extends battery life.

The actual runtime varies based on usage frequency and environmental conditions, but users typically report reliable operation for hundreds of hours between charges.

Can I use an Aimpoint AA battery in any red dot sight?

No, Aimpoint AA batteries are specifically designed for Aimpoint sights. While some third-party red dot sights may work with slightly different battery types, using an Aimpoint AA battery in non-Aimpoint equipment can damage both the battery and the device.

If you have a different brand of red dot sight, it’s important to use batteries specifically compatible with that manufacturer’s specifications.

How should I charge an Aimpoint AA battery?

Charging an Aimpoint AA battery requires specialized equipment. The recommended method is to use an Aimpoint-specific charger, which regulates the charging process to prevent overcharging and maximize battery life.

It’s important not to use standard USB chargers or wall adapters, as these may not provide the proper charging profile and can damage the battery.

What is the proper storage method for Aimpoint AA batteries?

Aimpoint recommends storing the batteries in a cool, dry place when not in use. The optimal temperature range is between 20-25°C (68-77°F). Higher temperatures can significantly reduce battery life and performance.

When storing the batteries for extended periods (more than 3 months), it’s recommended to fully charge them before storage and to recharge them every 3-6 months to maintain optimal performance.

Are Aimpoint AA batteries compatible with environmental conditions?

Aimpoint AA batteries perform well in typical operating conditions, including temperatures ranging from -20° to 60°C (-4° to 140°F). However, extreme temperatures can affect battery performance and lifespan.

During use in extreme cold (below -20°C), the battery’s performance may be reduced. Similarly, in extreme heat (above 60°C), the battery’s capacity may decrease. Proper temperature management helps maintain optimal performance.
