Battery OPTIMA or OEM FORD

Always read your manual/mfr suggestions for battery charging and longevity.

For Li-ion you generally should charge no more than 80% (some mfg hide 10% via software like Ford, so you charge to 90%). Also, limit fee cycling these types too, regularly you should DC to about 50% max. Occasionally deep cycling and full charging is fine. Should limit DCFC also.

I had an Optima red top in my 89 4runner and that thing lasted for 12 fucking years. Needless to say I bought another one.

Just did that on my 19 gsw, no battery management extra thing to deal with, just the two connectors and obd11 for coding to fleece (not binary agm). Only issue I have is the battery blanket doesn't fit the bigger size.

I have optima yellow and it’s lasted 150,000 miles so far and not slowing down

As previously stated. I have had an Optima Red Top in my Cabriolet for nearly 7 years and have never had a problem. During that that tiome, the battery sat out of the car for almost a year with only occasional bench top charging and was perfectly OK when put back into service. Also, recently I screwed up and left my lights on. The battery was dead dead the next morning. 1.43 volts present to be exact. Took some time but I was able to bring it back up, and it has been performing well ever since. Optima even has a video out about how to bring back a completely dead battery.

I have an Optima Red Top in my 1990 Cabriolet. I have been very happy with it. It is probably about 7 years old at this time and I have never had a problem with it. Otherwise, I would REC a DEKA branded battery. IMHO, "cheap" batteries are not worth the relatively small ammount of money saved.

A friend of mine had a 2010 ( or 2009 ) Fusion Hybrid that needed a new battery, he went to the dealer and he was quoted over $8K. He then found $3K 'aftermarket' batteries and at the end he was able to find a shop that did the whole thing for under $2.5K.

It literally is of 0 benefit and in fact they have shown to have a shorter lifetime in these applications.

Optimas quality fell off hard when they moved manufacturing to Mexico. They've been riding on their previous reputation ever since.

I went through two of them in a season in my trail Jeep. I think years ago they were great batteries and the quality was there but now it’s just a brand name but junk product.
