OPTIMA BATTERY AND NEW REGULATOR For all the nay sayer's my battery and electrics are really good with the adjustable regulator from IPD I was running around 13.2 volts charge now its around 14.6 and whata difference . Optima SAYS it is safe up to 15 volts and wow my car loves it .Every thing works better lights electric windows and such . It appears the older battery styles did ok with lower voltage but the newer batteries like a bit more juice and with Optima they charge quicker as well so I am well satisfied with the adjustable regulator and the optima battery . Got another Optima for my wife's car when her S40 t4 battery open circuited again excellent results .
5 Volvo,s and still love them inspite of the 264 cams and the frailty of the S40 t4 . John R
