Customer Reviews
On a typical cloudless day it will take these batteries from empty to nearly full in about 2 whole days. But it will not top them off and leaves them at 90%. When I tested them, I got a voltage of zero making sure they were dead. After a day they were tested at 2.7 volts (about 50%) charged. Next day they read 3.9 volts which is about 90%. When hooked up to a fast charger it took them to nearly 4.2 volts.Not perfect but close so I ordered a small army of these!
