Yale keypad locks are powered using four 1.5V AA alkaline batteries with an operating voltage of 4.5V to 6V. These generally last between 8 and 12 months depending on frequency of use. This estimation is based on an assumption that the door is used about 10 times every day. When the door is used more frequently than this, then batteries will not last as long.

Yale recommends that users stick to authentic alkaline batteries and stay away from rechargeable batteries.

Why Alkaline Batteries?

These are the main reasons why alkaline batteriesare best for your Yale keypad lock replacement

 Longevity: Alkaline batteries have a longer shelf life than other types of batteries. They can last up to seven years unused and lose only five percent of their energy every year they are left unused. Even whenthey are placed in a device, they don’t lose much power when the device is not in use.

Low Temperature Functioning: Alkaline batteries continue to function normally even in very low temperatures. This makes them suitable for use even during the winter.

Leakage: Although alkaline batteries have been known to leak, they are far less susceptible to leakage than other batteries. Leakage from batteries when left in devices for long can cause corrosion of circuits.

Safety: Alkaline batteries have less negative impact on the environment compared to lead-based and acid-based batteriesThey do not requirespecial disposal methodsbecause the compound contained in them does not pose any serious health risks.

The downside to alkaline batteries is that they are not as cost effective as rechargeables because they have to be disposed of once they are drained. Alkaline batteries are also considered environmentally unfriendly.

 Low Battery Alert

When batteries are running low, you will see a red, battery shaped light at the top right hand corner of the keypad. Some Yale locks have an audible voice which gives a verbal warning. You should have enough time to change the batteries before they are totally drained. There is no way of telling exactly how long you have before they are drained, though most users say it takes a couple of days. Besides frequency of use, battery life will also vary depending on atmospheric temperatures, humidity and quality of the batteries.
