FAQ Section: Your 18650 Battery Questions Answered

Choosing the right battery can be a bit tricky. Here are some common questions to help you out:

Q1: Why do video doorbells use 18650 batteries?
A: Video doorbells often use 18650 batteries because they offer a high energy density, meaning they can store a lot of power in a small size. This is perfect for compact, wireless devices that need to run for extended periods without constant charging. They’re also rechargeable, which saves you money and reduces waste compared to disposable batteries.

Q2: What’s the difference between “button top” and “flat top” 18650 batteries?
A: It’s all about the positive terminal! A “button top” battery has a raised, nipple-like positive contact, similar to a standard AA or AAA battery. A “flat top” battery has a completely flat positive terminal. Your video doorbell (or its battery compartment) is designed for one or the other, so checking this before purchasing is crucial for proper fit and function.

Q3: How important is mAh when choosing an 18650 battery for a video doorbell?
A: mAh (milliampere-hour) indicates the battery’s capacity. A higher mAh means the battery can store more energy, leading to a longer runtime for your video doorbell before needing a recharge. For devices like doorbells that are always on and often recording, a higher mAh (e.g., 3000mAh and above) is generally better for extended usage.

Q4: How often should I expect to recharge my video doorbell’s 18650 battery?
A: This varies greatly depending on several factors: the battery’s mAh capacity, how frequently your doorbell detects motion or is activated, video recording quality settings, and even environmental temperature. A higher capacity battery in a low-traffic area might last months, while a lower capacity one in a busy area could need recharging every few weeks.

Q5: Are 18650 batteries safe to use?
A: Generally, yes, modern 18650 batteries from reputable brands are safe, especially those with built-in protection circuits (overcharge, over-discharge, short-circuit protection). However, like all batteries, they require proper handling. Always use a compatible charger, avoid physical damage, and don’t expose them to extreme temperatures. Always purchase from trusted sources to avoid counterfeit or low-quality cells.

Q6: Can I use any 18650 battery in my video doorbell?
A: Not necessarily. While most video doorbells use 18650s, you must check two things:
1. Button Top vs. Flat Top: Ensure the battery’s terminal type matches what your doorbell requires.
2. Voltage: Most 18650s are 3.7V, which is standard, but always confirm.
3. Capacity (mAh): While a higher mAh is usually better, ensure it doesn’t cause the battery to be physically too large for the compartment.
It’s always best to consult your doorbell’s manual for recommended battery specifications.

Q7: How can I maximize the lifespan of my 18650 doorbell battery?
A: To get the most out of your battery, consider these tips: avoid fully discharging the battery often (recharge before it’s completely dead), use a high-quality charger, avoid extreme temperatures (both hot and cold), and if your doorbell has power-saving settings, utilize them.


Final Thoughts

Choosing the best 18650 battery for video doorbell really comes down to matching the right battery type (button top vs. flat top) and capacity to your specific device’s needs. Whether you prioritize a massive capacity for ultimate longevity like the Emaks 7000mAh for AOSU, or robust safety features and wide compatibility like the AFSONGOO options, there’s a perfect 18650 out there for your smart doorbell.
