Troubleshooting – Eufy camera battery replacement

Batteries die for many reasons. Recharge cycles is usually not the issue as it’s of the order of 300-500 cycles and a battery lasting a year will get 1 or 2 cycles. More common next is it was allowed to get too cold or too hot. For an outdoors camera I’d expect this to be the dominant factor deciding death age of cells, and so the more violent the weather (below freezing or hot weather) the battery will age fastest.

What is the battery life and capacity? From a single 5 hour charge receive 180 days of battery life. The battery capacity is 6700mAh.

How do you replace a Eufy Battery? The short answer is you can’t. Removing the battery will result in damaging the security camera. The waterproof rating will be ruined. Only the manufacturer or a qualified technician can change or replace the battery.

Why it is not possible to do Eufy camera battery replacement?

These wireless security cameras run on a 13,000 milliamp hour battery. These batteries consist of four cells, the same of which is used by Tesla in their cars. You might be wondering why you can’t replace the batteries? Let me explain why you probably never will need to change the battery for this.

These wireless security cameras only need to be recharged once per year. You could literally run this camera for up to 1000 years before the battery degraded. Only Tesla of course used 10s of thousands of these batteries! Lithium ion batteries are usually rated to be recharged over 1000 times.

So unless there’s a fault in your particular unit, there’s no reason to even think about changing the battery.

As a side note, if you’re worried about someone stealing the camera if its externally mounted then a 100db alarm is triggered if it is removed from its mount.

If no choice except Eufy camera battery replacement?

Batteries are not replaceable. Opening up the housing will ruin the waterproofing!

However, if you have no choice and you have to try to attempt to replace the batteries, then this is what I would do.

Be very careful when you disassemble the security camera. Remember, you’re only wanting to replace the battery and the last thing you want to do is to damage the other electronic components of the security camera. An I Fixit kit. Used for building laptops and PC’s would be really useful for this purpose.

Here’s a link to a kit that I would recommend. It’s also super useful for any electronic disassembly tasks.

You could in theory buy some tesla style batteries and replace the existing ones, but in all honestly this isn’t worth your time and you’d potentially break the camera in the process if you didn’t know what you’re doing. Plus the waterproofing would be ruined.

Once you have access to the batteries, simply replace them with your replacement parts. Reassemble the security camera and cross your fingers.

As I have mentioned earlier Eufy have designed the camera for the last years so it is unlikely that you’ll need to replace the battery during the product’s life span.

If you have a Eufy Cam 2C then the battery only lasts 6 months which is worth taking into consideration.
