What does it mean PAO 80?

if one is bad the others are close behind. i rec all 3 batteries or test each battery to determine bad one.ck on line for cost i think it will save you alot of $

I would have the dealer check the connections in the Hybrid battery pack. The connections that tie all the individual batteries together have a problem with corrosion. However if 1 of the batteries in the pack are bad, you should replace them all.
