for clock, use cheap carbon zinc battery, dont even need alkaline..

Rechargable at full charge only dish out 13.4v and not close to 1.5v, so clock might run slower. After a while with it will only put out like 1.2v then you will lose few minutes every month.

Also rechargable not suitable for slow drain battery, more for fast drain like Alkaline replacement.

I stopped using alkaline batteries or normal batteries. All switch to rechargeable battery.

The chemical leaking corroded my device. And an expensive device.

for me is remote.. just a IR diode and basic signal circuit. if u have a LED torch light that use 1.5V battery, can use it too.. it will be dimmer, that will be the most basic one.

theres quite alot of engineering that goes into clocks or timekeeping device

changes in the voltage can somehow make the accuracy deviate AFAIK, like for example if you set in clock 1pm to tie with official time, then due to issues with the clock when its 2pm your clock still shows 1.55pm or something like that

thats one of the reason why some watches are so darn expensive, cause their device have to also guarantee super precise timekeeping

The quartz crystal is responsible for time keeping and doesn't really care about 1.2V from rechargeables. But the part I circled in red does. It's a puller solenoid responsible for the clock movement and it need the 1.5V nominal from alkaline/zinc carbon battery.

You still can use rechargeable battery, just charge them more often.

I have heaps of AA/AAA batteries as well. No leaks are the bonus. but clocks and remotes, I still use alkaline/zinc batteries, the rest are all rechargables.

Camera and Flashes are recommended not to use Nimh batteries though.
