Rechareable Battery for the Ring Solar Security Sign

The light on my Ring Solar Security Sign no longer comes on at night even though it gets numerous hours of direct sunlight every day.

So, I am trying to find a replacement 14430 LiFePO4 rechargeable battery.

Problem is all of the sources I found sell packs of multiple batteries & I only have 1 Ring Solar Security Sign.

Also most of them are “Made in China” & I have no confidence that they will last for even a reasonable amount of time.

Does anyone know of a reliable source for that battery? Preferably a reliable “brand” named battery?

Or, even a charger for that battery?

Does Ring not sell that battery or a charger for it?
