Be aware
These batteries don't hold the charge even for 10 seconds. left them to charge for over 24 hours and when unplugged it to take it the other location they turned off immediately.so it doesn't matter if they are good value when they don't work.

Good but pricy
These perform to spec. But pricy.No complaints because I prefer stuff that works and lasts.Would recommend.

Defective, will not charge
No charge out of the box, will not charge. 100% defective.

Box of 4 only had 3 batteries while an other box had water damage
One box clearly was wet at some point since the outside of the box was discolored. A second box only had 3 batteries (out of the 4 ordered). The polarity is reversed, so these are not compatible with most Arduino development boards.

Buone batterie
Prodotto che non mi ha dato ancora nessun problema nonostante un uso giornaliero dall'acquisto. Ovvio che piano piano si riduce la carica totale, si sa, ma ci vuole tanto perché si degradino fino a non poterle più utilizzare.
