I received two batteries and charged them using aLithium cchargerto ffull charge. One battery has a small discharge even tho it us not connected. I tried to contact Renogy viatheir aapp for techsupport but the app kept failing. I have reached out via email but took them awhile to tell meit's been referred to tech support.
Now I see thatthe bbatteries are even cheaper and wonder if they will offer replacement or refund. Also, batteries are not the same as photo above which shows terminals on one end. Mine are spaced on opposite ends.
Only one of the two is holding charge.
Hope tech service can respond. Not much faith tho since I previously had two Renogy batteries that failed right asthe warranty ran out. They offered me 15% discount on anything on their site.... But would not honor it on sale batteries.
Frustrating too since same battery is now offered at a price that would be equivalent tothe 15% discount.
Not Impressed.
