Anyone using rechargeable CR2 batteries with Iris motion sensor?

If yes which one’s and how is the performance? Any recommendation on which batteries are best value for money, rechargeable or non rechargeable?

Most manufacturers recommend not using rechargeable batteries in home automation devices because the “battery life remaining” reports will end up being wildly inaccurate as the depletion curves are very different than the regular batteries for which those reports are designed.

Even worse, the most typical inaccuracy is that the battery report will say there is still about 35% of battery life remaining and then the battery will die the same day.

For home automation, predictability is usually important, which is why the manufacturers suggest that you not use them.

If you don’t have a problem with your devices going off-line because of unpredictable battery life, then you can certainly consider them.

At what percentage to change batteries in Schlage lever lock?

Most lock manufacturers advise against using rechargeables in locks. The problem is that rechargeables have a very different usage pattern. They would look like they are almost full charge for a very long time and then drop off very quickly. For this reason all of the usual “low battery” warnings, including those built into the lock themselves, won’t report correctly when when rechargeables are used. And because it tends to be so inconvenient when a lock isn’t working, non-rechargeables are preferred. https://www.schlage.com/en/home/faq.html?what-type-of-batteries-should-i-use Undesirable Operation: At the end of life for lithium batteries there is a very steep discharge curve. This means that when the batteries do die there will be little or no warning, which increases the likelihoo…
