New Genuine Spare OEM BL-51YF Replacement Battery for LG G4

Just reminded me...forgot to put the old one back in. This was to be a "spare". For under 8 bucks, free shipping, made by "LG" and arrived in 3? days not to shabby! The thing is I may never need it much cause the LG G4 is only 1.5yrs old. But nice to have extra spare power. These seem to charge fairly quickly. Came well wrapped in a little plastic bag and thin cardboard box and shipped in small size envelope. TAKE NOTE USPS: the envelope is "ok", but what would happen if smashed w/a hammer? Anyhow; All phone batteries tend to be a bit soft and can be dented. STORE ALL THESE BATTERIES SAFELY IN A GOOD CONTAINER IF NOT IN YOUR PHONE!!! Has built-in "IC reg" to stop over charging for extra safety. This phone does drain these batteries, "4k display". Well, need to charge this up and put the old battery back in. I'll have to check to see how long the new one will hold its' charge in storage. Humm, where did I put all those old phones..."battery hunt" !
