Are you tired of constantly changing batteries for your electronic door lock or smart lock? The key to avoiding this inconvenience lies in finding the best batteries for these devices.
Smart locks have become increasingly popular due to their convenience and enhanced security as technology advances. However, the performance of these locks heavily relies on the batteries powering them. Investing in high-quality batteries that keep your lock functioning efficiently for an extended period is crucial.
Top 3 Batteries for Digital Door Locks
When choosing the best batteries for Kwikset locks, Schlage locks, Yale door locks, and Schlage Encode, it’s essential to prioritize long-lasting and reliable power sources. Most smart locks require high-quality alkaline AA batteries, with brands like Duracell Coppertop and Energizer Max being top recommendations. These batteries provide consistent voltage and extended lifespan, ensuring smooth operation. For Schlage Encode and other Schlage smart locks, avoid lithium or rechargeable batteries, as they can lead to performance issues. Similarly, Kwikset locks and Yale door locks function best with standard alkaline batteries, offering optimal power efficiency.
To maximize battery life, ensure proper door alignment, as excessive resistance when locking/unlocking can drain power quickly. Checking battery levels regularly and replacing them annually or when prompted helps prevent lockouts. Avoid using cheap or no-name batteries, as they often have inconsistent voltage output.

How do I replace the batteries on the Smart Lock?
When you first decide to invest in a smart lock, one factor needs to be considered: battery life. While some people don’t want electrical wiring for their front doors and are glad to have an option for battery-powered locks, others don’t just want a lock but a completely automated solution.
Storing batteries is still a huge issue with manufacturers. As a result, they’re not consistent in the level of battery life they provide their consumers. But despite this lack of consistency, there are still some situations where you can use more than one battery to extend your smart lock’s battery life.

What type of battery does a Yale lock need?
It depends on which model you have, but here are some common battery requirements and tips from Yale:
- Many Yale Smart/Assure locks use 4 × AA Alkaline batteries.
- The Yale Linus® Smart Lock L2 uses a rechargeable battery pack (USB-C) with about 6 months of expected battery life.
- The lock gives a low battery indicator (often via LED or in the app) when batteries are almost dead. Mixing old/new batteries is discouraged.
What to look for in good batteries
To get the best performance, here are the key features you want:
| Feature | Why it matters |
|---|---|
| 1. Alkaline, high-quality AA cells | Yale often specifies non-rechargeable alkaline AAs for many models. These give stable voltage under load. |
| 2. Low internal resistance | Helps the lock’s motor work efficiently, especially when driving the bolt. High resistance causes voltage drop, poor performance. |
| 3. Good shelf life / leak resistance | You don’t want the batteries to corrode contacts or fail prematurely. |
| 4. Battery chemistry that works well in temperature extremes | Hot or cold weather can reduce battery output; good brands maintain better performance. |
| 5. If using rechargeable, ensure compatibility | Rechargeable often have slightly lower voltage (1.2 V vs 1.5 V) which may work, but may also reduce motor strength, so check if your model tolerates them. Linus L2 is designed for its own rechargeable pack. |
What I recommend for different scenarios
Here are suggestions depending on how you use your lock:
| Use-case | Best battery choice |
|---|---|
| Heavy/daily use (many unlocks, frequent motor action) | Go with premium alkaline (Energizer Max, Duracell Ultra Power) or the Yale-approved battery pack (if you have Linus L2). Keep spare set nearby. |
| Average daily household use | Standard quality alkaline AA from a reliable brand. Replace when low-battery alert appears. |
| Frequent battery changes are inconvenient or you’re eco-minded | Consider the Yale rechargeable pack (for Linus) or good quality NiMH/other rechargeable AA set only if your Yale model can handle them. Clean contacts and ensure full charge. |
| Extreme temperatures | Lithium AAs tend to perform better in cold; also premium alkaline outperform generic ones. Ensure the brand specifies performance under temperature extremes. |
If you tell me which model of Yale lock you have (e.g. Yale Assure SL, Linus L2, Yale YDR41A, etc.), I can suggest which single battery option is best in your locale, so you can just go buy the right one. Do you want me to do that?
Their non-stop energy powers your devices as they work in and out of storage, ensuring they’re always ready when you need them most.

Frequently Asked Questions – Smart Lock Batteries
❓ What smart lock has the best battery life?
Smart locks with efficient power management usually last the longest. Models that use Bluetooth or keypad-only access tend to consume less energy than Wi-Fi–based locks. Brands like Schlage, Yale, and August are well known for solid battery performance, especially when paired with high-quality alkaline batteries. In real-life use, many homeowners get 6 to 12 months of battery life with regular use.
❓ What kind of batteries do smart locks use?
Most smart locks run on AA or AAA batteries, which makes them easy to replace and widely available. Some locks also use CR2032 coin cell batteries for backup memory or internal functions. Always check your lock’s manual—using the correct battery type helps prevent errors and short battery life.
❓ Are lithium or alkaline batteries better for door locks?
For most smart locks, high-quality alkaline batteries are the better choice. They provide steady voltage and are designed for devices that need consistent power. Rechargeable lithium batteries often deliver uneven voltage, which can confuse smart locks and trigger low-battery warnings too early. Unless the manufacturer specifically recommends lithium, alkaline is usually the safer option.
❓ What is the best battery for a door lock?
The best battery for a door lock is one that’s reliable, long-lasting, and brand trusted. Batteries from Energizer, Duracell, Rayovac, and Amazon Basics consistently perform well in smart locks. The key is not just the brand, but also replacing all batteries at the same time and avoiding mixing old and new ones.
❓ What brand of CR2032 batteries last the longest?
For CR2032 coin cell batteries, brands like Energizer, Duracell, Panasonic, and Sony are known to last the longest. These batteries are often used for backup power, so even though they’re small, quality really matters. Cheaper versions may drain quickly or fail unexpectedly.
❓ Why are the batteries in my Schlage lock dying so fast?
Fast battery drain in a Schlage lock usually happens for a few common reasons:
-
Low-quality or mixed batteries
-
Frequent use or heavy traffic doors
-
Extreme heat or cold
-
Weak Wi-Fi or Bluetooth signal causing extra power use
-
Using rechargeable batteries instead of alkaline
Switching to fresh, name-brand alkaline batteries and replacing them every 6–9 months can make a noticeable difference.
