Well, I couldn’t do a +5 or +6 as the battery was dying and wouldn’t take a reading. I had three spares, but they were from yrs ago so didn’t really work either. Decided to keep as much juice as possible to get a reading this morning, and got a 301 -yuck at +9.5......so now just fed them and will soon go to the store that opens at 8am and get some new batteries in time for amps. Well, at least I got an extra couple hrs sleep straight thru
