I live in Minnesota and even in extreme cold, these do a good job in my flood lights. Not sure if -10F is okay for them, I make sure they get to room temperature before charging, but they've been working great for 2 years. If you have problems, the customer support is amazing as well.!

The batteries are awesome...love them...original packaged came in damaged caused by USPS not Paleblue. Email response was a little slow but not bad considering the xmas rush but they took care of the situation. Would definitely recommend..

I have only tried the batteries in my beard trimmer, which works well with the pale blues. I can't vouch for the length of use per charge, as I haven't used them long enough to drain them.

I have made several purchases from Paleblue and I love their product as well as their customer service. I had one battery (out of many so far) which did not appear to charge. I emailed customer service and was sent a new replacement battery quickly and with absolutely no hassle. I plan to continue purchasing Paleblue batteries as I transition my whole household from one-time use batteries.

Always running out of C batteries for flashlights. These help alot.

I’ve been using their batteries for a while now, mostly in a gps for hunting. Charge fast and last all day. The new ones I purchased as a gift was a bummer, because the solar panel shipped with only one set. They did send me a second set of batteries, like the description said, but I’d already gifted the panel and original set of batteries unknowingly. Then I get an email about a free gift, and it was another set of AAs, supposed to be AA and AAAS. Wasn’t a free gift, it was what I had bought just shipped separately. Annoying as hell

Love these batteries especially when camping - can always depend on having lights and our camp fan. Plug them in by day - up and running by night

I am thankful that I don't have to buy batteries every time that I turn around, I have wasted years and lots of money on batteries that have died before even being used, NO MORE, Thank you Pale Blue.

Great

I tried these batteries in my toothbrush and they work like a champ. Will order more.

These batteries are AWESOME. Easy to charge, and the case is handy for storing the cable and the batteries.

I will be buying more bye bye reg.batteries!

super deal

easy to use the charge keeps me able to keep a soft light in the room for my sister with dementia who cannot tolerate much light at night especially. so the soft light has given her light to see but not to be bothered by.

Great product.
