What type of battery is recommended for this lock, and what is its expected battery life?

 Duracell Ultra: For the SE and Plus models, use 4 AA batteries, and for the Pro Lock, use 8 AA batteries. The battery life typically lasts 4-6 months for the SE and Plus models, and 2-3 months for the Pro Lock, depending on the usage.  

We recommend Duracell Ultra batteries to all our customers. During our R&D phase, we tested various batteries, and when compared to other brands, we found Duracell Ultra to have the best efficiency. Our product and engineering teams also recommend these batteries, and we've tested them with our support locks. On average, these batteries last 4+ months, with some even going over 6 months.

The Duracell Ultra batteries are available on Amazon and Flipkart, or through platforms like Blinkit, Instamart, or Zepto. Depending on your pincode, you can choose the most convenient platform to purchase the batteries.
