Aimpoint PRO Battery Life and DL1/3N Replacement

Aimpoint PRO Battery Life and Replacement

The Aimpoint PRO is known for being a durable red dot sight with great battery life. According to Aimpoint, the battery (type 2L76 or DL1/3N) will last up to 3 years of continuous use with the optic set on setting 7 out of 10. So, how accurate is that expected battery life?

About 3 weeks ago, the battery in my Aimpoint PRO, which is mounted on the VPS-15 rifle, finally gave out. I may be off by a few days, but my best estimate is that the battery lasted 777 days (2.1 years). However, it did see some frequent use above setting 7, so I think Aimpoint’s battery life estimate is certainly in the ballpark.

Aimpoint PRO Battery Replacement Tip: I wasn’t able to find a DL1/3N replacement battery for the Aimpoint PRO at any of my local stores. So, it was necessary to order the battery online. Do yourself a favor… To prevent paying ridiculous shipping fees for a $4 battery, add an extra DL1/3N battery to your order the next time you make a purchase at your favorite online gun accessory retailer. DL1/3N batteries are available at Brownells!

*In addition to the Aimpoint PRO, the Vidalia Police Supply VPS-15 pictured above features the ArmaDynamics ADF-MKII charging handle, Magpul accessories (CTR Stock, MOE SL Grip, MOE RVG, MBUS PRO Front & Rear Sights), and a Hexmag Series 2 magazine.
