I only got 3 working batteries after paying the seller for 4 batteries. How can I contact them?
You can contact us through email or the service email on the back of the box, we will send you the replacement for free.
What is the weight of a single AA in grams?
I can tell you that the AA Li-Ion version is 17 grams, NiCd AA is 24 and AAA is 12.
How long does the charge last while not in use?
It has a high retention at mid-charge, and will die out within 2 weeks if it drops under 20%.
I'm afraid the batteries will catch fire if they reach temperatures over 140 degrees.
It is too hot and should not be used. Even though it is not a safety valve, it is a fuse that can break and can't be reset, but you should be protected against a fire like the seller pointed out.
Does the port only charge the battery or can you charge things from theusb as well?
The 4 in 1 usb cord is very short, but it works.
