TV remotes are necessary to enjoy a smooth entertainment process, and just like any other battery-powered gadgets, they come to a halt when the batteries are depleted. The batteries are not difficult to replace, but most users are confused because of the numerous models of the remotes and the types of batteries. It can save you time, frustration, and unwarranted costs whether you are working with a simple infrared remote, a smart Bluetooth-enabled controller, or a more expensive universal remote, by understanding how to safely and properly replace the batteries. We will take you through it in this guide, including how to find the right type of battery, step-by-step replacement of various types of remotes, maintenance, and problem-solving of the most common problems.
Understanding TV Remote Batteries
Most TV remotes might resemble each other, but the type of battery can be very different, depending on the model. Normal remotes are powered by AA or AAA alkaline batteries, and thinner or specialized remotes might need button cell batteries like CR2032. The more expensive or intelligent remotes will usually have built-in rechargeable lithium-ion batteries that are intended to be used frequently and have increased power requirements.
The selection of the appropriate battery is crucial to the best performance and extended life. Alkaline batteries are the most reliable in the daily use of remotes and lithium batteries in the high-drain gadgets such as smart remotes with voice or Bluetooth capabilities. Though rechargeable NiMH batteries can also be used, they can also give low battery notifications too soon because they have lower voltage.
Always look in the battery compartment to see signs of the appropriate battery size and polarity (+/ -). Old and new batteries should not be mixed or of different types because this may cause leakage or reduction in battery life. When you are not intending to use the remote over a long time, then take out the batteries to avoid corrosion and maintain your device.

- AA Batteries: These are the most common and are used the most as cylindrical.
- AAA Batteries: These are smaller in size compared to AA, and usually cylindrical and found in smaller remotes.
