The primary considerations are voltage, capacity (measured in mAh), size, and chemistry.

Common Battery Types And Their Characteristics

*Note: Capacity figures are approximate and can vary by manufacturer.*

Why Lithium Coin Cells Are Preferred For Remotes

Lithium coin-cell batteries like the CR2016 and CR2032 are the industry standard for garage door remotes and many other small electronic devices for several compelling reasons:

• Consistent Voltage: They provide a stable 3-volt output, ensuring consistent performance for the sensitive electronics within the remote. Alkaline batteries, conversely, experience a voltage drop as they discharge, which can lead to intermittent operation.
• Long Shelf Life: Lithium batteries can retain their charge for many years (up to 10 years or more) when stored properly, making them reliable for devices that aren’t used constantly.
• Compact Size: Their small diameter and slim profile allow for the creation of compact, ergonomic remote controls that are easy to hold and operate.
• Temperature Tolerance: While extreme temperatures can affect any battery, lithium cells generally perform better in a wider temperature range compared to alkaline batteries.

Using the correct battery type is essential. Substituting an alkaline battery for a lithium coin cell, even if the voltage seems compatible (e. g. , using two 1. 5V AAs in series to achieve 3V), is generally not advisable due to differences in discharge characteristics, size, and potential for leakage.

Always adhere to the battery type specified by the manufacturer for your Access Master remote.
