I purchased, and installed a set of these Tenavolts 1.5 V AA Lithium Rechargeable Batteries on amazon for $34.99 after seeing that one set of the Energizer Ultimate Lithium AA Batteries at home depot for $23.87.
I decided that for $11.12 more, I’ll experiment with a set of batteries that if they work, I’ll hopefully save a few dollars.
The batteries started at 94% upon installation per the Wyze App on 08-07-2022,
Eight days later (today), still showing 94%
It’ll be interesting to see how they perform. If I get any type of warning of a low battery event, or if they just go ‘completely’ dead without warning.
I’ll update this post on the next exciting blockbuster episode of 'Batteries Discharging in a Wyze Lock" when something of note occurs.
If they don’t work out in the Wyze Lock, I’ll find another user for them elsewhere and try something else.
[Mod Edit]: Linked product to Amazon.
The forum wouldn’t allow me to reply to my own thread:
So here I am per that suggestion, and editing my original reply to document what I discovered with the Tenavolt batteries:
My Wyze Lock Quit working yesterday, no warning of a low battery (which I understand is the expected behavior with the Wyze Lock and rechargeable batteries)
So, I pulled the batteries, grabbed my high tech battery meter and saw what I expected:
EXCEPT for one of the batteries was not like the other three:
Strange that three fully discharged, and one did not.
I will label them 1-4 this time, and mark the inside of the lock with 1-4 to see if one of the batteries does this again, and if so, which battery slot doesn’t discharge like the other three.
For this experiment, the batteries lasted from 08-07-22 to 10-25-22 for a total of 79 days.
But if I get 1000 cycles out of batteries per the box…
1000 cycles x 79 days = 79,000 days
79,000 days / 365 days = 216.43 Years
If my math is right… and it lives up to even half of that expectation. the batteries will outlive me…
(There has to be a flaw in my math and / or reasoning here, as I can’t believe these batteries will last that long)
Did I flunk this math test?
