Very good

5-2-2024 Weather station needed replacement rechargeable that had very specific capacity AND size. This is done as to not have rattling around to where the sensors give off false readings, So far, the battery are maintaining a 2.8-2.83 battery capacity and the weather station has been reporting accurate measurements which leads me to believe that we have a clear winner in this battery. Now, you will need to make modifications (ie soldering leads) to the battery but nothing too terribly difficult if you know what you are doing. And finally, do NOT forget to apply dielectric grease to the finished install as was done on the original board. This battery is a clear choice thus far. Thank you, Hakadi for your product!!

I purchased 4 x 18650 Sodium Ion batteries simply out of curiosity, on test they lived up to their specifications.
I will try some of their 10ah Sodium Ion batteries next time.

Excellent

I buy sodium ion battery from this vendor and everything is ok

Shipped quickly and securely and at a decent price. Will be buying from them again for sure.

I have tested the akku for a short, and it works fine. I missed a note telling some data about the akku. Luckily I found a youtube with the missing data.

very good service, fast shipping

I have used you batteries to make a DIY Power Bank [the cases available on the internet-you supply your own batteries] for charging cell phones. They work fine in this application. Work just as well as the 18650 and fit in the Bank Case just as well as the Lithium 18650 batteries.. Nice to know I have a safer Power Bank.

Please check title name of page. The battery is not NiMH
