Alkaline Vs. Rechargeable

Batteries are an essential component of Schlage locks, ensuring their smooth functioning. When it comes to choosing the right type of battery, there are two primary options: alkaline batteries and rechargeable batteries.

Alkaline batteries are the recommended choice for Schlage locks. They offer consistent battery power, making them suitable for use in smart locks. However, they are single-use and not environmentally friendly, as they require regular replacement.

Rechargeable batteries, on the other hand, are reusable, making them cost-effective and more environmentally friendly. Unfortunately, Schlage does not recommend using rechargeable batteries in its lock systems, as they may not provide adequate power and compatibility for the lock mechanism.

Types of Batteries

Schlage locks use different types of batteries depending on the model in question. Here are common battery types for various Schlage lock models:

  • AA Batteries: A popular choice for many Schlage locks, such as Schlage Connect and Sense Smart Deadbolt. These alkaline batteries typically last approximately one year before requiring replacement.
  • 9-Volt Battery: Schlage BE365, an older model, relies on this type of battery. Whether you are using an alkaline or a rechargeable battery, the same rule applies – it must not hinder the lock’s power-taking capacity.
  • AAA Batteries: Smaller in size, these alkaline batteries are used in models like FE575 and FE595.

When it comes to battery life, factors such as usage frequency, lock features, and battery quality can impact how long they will last. For instance, increased power-taking features, such as Wi-Fi connectivity, may cause faster battery drain. Consequently, regular battery changes are essential to maintain your lock’s performance.

To replace batteries in Schlage locks, follow these steps:

  1. Remove the interior cover: Locate and remove the screws securing the cover in place to reveal the battery compartment.
  2. Remove the old batteries: Gently take out the old batteries from their compartment.
  3. Insert new batteries: Place new, high-quality alkaline batteries according to the proper orientation (matching positive and negative terminals).
  4. Reattach the cover: Securely replace the interior cover with the screws.

Always pay attention to the critical battery warning or low battery indicator on your Schlage lock to avoid being locked out due to power loss.

Troubleshooting Battery Issues

Dealing with Weak Wi-Fi Signal

A weak Wi-Fi signal can potentially cause issues with your Schlage Encode lock’s functionality. To ensure smooth operation of your lock, follow these tips to improve your Wi-Fi signal strength:

  1. Place your router in a central location in your home, away from large appliances and other sources of interference.
  2. Keep the distance between your Schlage Encode lock and router minimal.
  3. Upgrade your router firmware or invest in a modern router with better performance capabilities.

If you’re experiencing difficulty connecting to the Schlage Home app, note that Bluetooth may also be affected by weak Wi-Fi signals. Try these steps to improve your connection:

  • Turn off Wi-Fi on your smartphone temporarily to force the connection over Bluetooth.
  • Ensure that your smartphone’s Bluetooth is enabled and that you are within range of the Schlage lock.

Confronting Critical Battery Warning

A critical battery warning can result from using improper batteries or due to natural depletion over time. Here are some steps to help you confront a low battery situation:

  • Use only non-rechargeable alkaline AA batteries. Rechargeable batteries are not recommended for use in Schlage locks as they can cause undesirable operation.
  • Replace your lock’s batteries as soon as a critical battery warning appears to ensure continuous lock functionality.

Pros and Cons of Using Rechargeable Batteries in Schlage Locks

Benefits of Using Rechargeable Batteries

Rechargeable batteries can offer you several advantages when used in Schlage locks. These points highlight the main benefits:

  1. Cost savings: One of the primary reasons for using rechargeable batteries in your Schlage lock is the potential cost savings. You can use the same set of batteries for an extended period, eliminating the need to frequently buy new ones. This can save you a considerable amount of money in the long run.
  2. Environmental-friendly: Using rechargeable batteries reduces the need to throw away single-use batteries, making it an eco-friendly choice for your home security needs. Rechargeable batteries produce less waste and reduce your overall environmental impact.
  3. Convenience: As most Schlage locks, such as Connect, Sense, and Encode, have user-friendly interfaces and indications when the batteries are low, you can easily recharge your batteries when needed, ensuring your smart lock is always up and running.

Drawbacks of Using Rechargeable Batteries

Despite their benefits, there are also some drawbacks to using rechargeable batteries in your Schlage lock:

  1. Lower voltage output: Rechargeable batteries typically have slightly lower voltage output compared to disposable ones. This difference can potentially reduce the performance of your Schlage lock, impacting battery life and reliability.
  2. Frequency of recharging: Depending on the smart lock’s usage and features, you might need to recharge the batteries more frequently than expected. For example, Schlage locks with Wi-Fi capabilities, such as Encode, can put additional strain on the batteries due to continuous connectivity.
  3. Rechargeable battery lifespan: While rechargeable batteries have a longer lifespan compared to disposable ones, they still have a limited life cycle. Over time, you will notice a decline in their performance, which might require you to eventually replace them.

In summary, while rechargeable batteries can provide cost savings and convenience for your Schlage locks, they may also come with some drawbacks, such as lower voltage output and a limited lifespan. By carefully considering these pros and cons, you can make an informed decision on the best battery option for your home security needs.


In conclusion, it is important to understand that rechargeable batteries should not be used in Schlage locks. This is primarily because Schlage keypad/smart locks are designed to be powered by non-rechargeable alkaline batteries.

Using rechargeable batteries in your Schlage lock may seem like a cost-saving solution, but it is not recommended due to potential compatibility issues and the lock’s design. Instead, you should opt for non-rechargeable alkaline batteries that are specifically designed for your Schlage lock model.
