Prius hybrid battery mountain drivinh
I drove 1800 miles from VA to Taos NM in 2007 Prius. My battery was fabulous
up till I had to climb to 8000 feet. I replaced the hybrid 4 years ago with after
market battery. At times the battery bars would go to purple then back to 3 or 4
blue bars while climbing the mountain. It regenerates fairly quickly when on
flatter and down hill to green briefly. The quick depletion is a serious concern
and the quick regeneration on the downhills. It is probably going bad again, or
the 2007 Prius just isn't happy climbing steep 1000 feet climbs. BTW the
speeds were 40 mph (speed limits) no problems. Any ideas?
