55 Watts is 55 Watts, doesn't matter if it's HID or halogen. Power (W) = Current (A) * Voltage (V).
It's garbage. I've had half dozen optimas over the years, the first few were excellent, the last few were garbage. I heard they moved manufacturing facilities and when that happened it all went downhill??? I"ll never buy another one again.
Yup many may be made at the same manufacturer, but that doesn't mean their quality will be the same. A walmart battery isn't getting the same exact things as a Motorcraft OEM one. A lot may be similar, but there's a reason one is OEM and costs more, and one is on the rollback special lol.
My stock battery died last month. 11 months old. NO electronic mods. Didn't leave anything on. Sat for 4 days and it had THREE volts on it. Red dot on the battery too. Dealer didn't even want to give me an appointment, but they finally did and they replaced the battery. Only the OEM ones have the little window, the replacement motorcraft ones don't.
If optimas are going down hill, which would you recommend.
