Can a 10440 battery be used in place of a standard aaa? will the higher voltage harm the light?

Yes and it does no harm to the flashlight.

Is it normal that the charged battery is empty after 2 months not used, and including extra AAA after 3 months?

I don’t think that’s normal. Mine keeps charge and u use regular.

can I charge a phone off the usb c port?

Thanks for your question, no, you can't charge a phone off the usb c port.

Will it be an issue using a fast charger to charge this light?

You can use the fast charger to charge to flashlight, because it has the Resistance protection plate inside, but we suggest you use the 5V-0.35mAh charger. Thank you so much for your question.
