I just received an email from ST indicating that they’ve discovered an issue with the 2.0 firmware version 0.16.9, which may cause the battery backup to deplete sooner than expected. A firmware updated is expected.
It goes on to say that a depleted battery may produce a white crusty powder. As a child, I remember many a battery powered toy being rendered useless from this substance.
So out of curiosity, I popped the bottom cover off my HUB. To my surprise, 3 of the 4 batteries were solidly encrusted with the white substance. My HUB is under a year old.
I’m really grateful that ST sent out an email regarding this, and I’m even more happy that I decided to check my batteries.
Is there a way to see the battery health from the IDE or otherwise? Does the HUB send a warning when the batteries are getting low, or when there is a fault?
I would highly suggest that everyone pop the cover off and take a peek.
It’s not just Kirkland’s brand. ALL brands have leaked so far.
Potassium hydroxide is a caustic agent that can irritate the respiratory system, eyes, and skin, you may want to take a precautionary extra step of using vinegar or lemon juice (both acids) to neutralize the alkaline build-up. Use a Q-tip or an old toothbrush and carefully wipe away.
