" ...  So I was very hopeful and herd good things about this battery so I went ahead and ordered it july of 2020. ... It won't even take a charge.  ...  "
comment
" ...  Original battery lasted for 10 years -- this one did not make it to 4 ... The car is not used that much and that could be a factor, but the use characteristics were the same for the old battery. ... I checked for parasitic usage and there was a draw of 40-50mA with everything turned off, and a battery like this ought to be able to handle this.  ...  "

" ...  UPDATE: On February 15, 2022 my battery symbol popped up so I went to AutoZone to get this battery checked. ... Results came out as "bad battery".  ...  "
comment
" ...  So now its a year later and the battery is shot. ... It will barely charge and die almost immediately. ... Seems lots of people are having the same problem and these batteries don't seem to live up to their marketing and I now won't trust them.  ...  "

" ...  It will fail in 6-12 months and you are going to end up spending a lot of your time trying to get it replaced. ... When it first started failing from a bad cell I almost had them ready to replace it, but then they (Optima) decided I had to take it somewhere that can test it and print out a report that states how they tested it and why it failed.  ...  "
