The versatility of Aimpoint sights such as the CompM4 and CompM5 series, accommodate both lithium and alkaline batteries. These sights were ingeniously designed with an alkaline battery option, driven by the specific requirements of customers like the United States Army.

In situations where transportation and shipment of lithium-ion batteries pose significant challenges, the choice of a more stable alkaline battery emerged as the preferred solution. This strategic decision ensures smoother logistics and enhanced safety.

However, it's important to note that the primary concern associated with these red dot sights is not the sight itself, but rather the battery within. Alkaline batteries can exhibit corrosive behavior as they deplete, which can lead to complications within the battery compartment.

When dealing with such issues, there are varying degrees of solutions. Simple fixes involve cleaning the compartment and replacing the cap after removing the battery. In cases of extensive corrosion causing internal damage, we offer a hassle-free RMA process through their website's warranty and service section at aimpoint.us/warranty-service.

While both lithium and alkaline batteries are suitable options, alkaline batteries may be slightly more prone to leakage and corrosion over time. On the other hand, lithium batteries offer a more reliable performance, especially in diverse temperature conditions. Make informed decisions to optimize the performance of your Aimpoint sights with the right battery choice.
