My stock battery is showing some signs that it is loosing some juice even though the battery technician told me that it still has some life left on it. I checked Motolite for DIN66 and was surprised to know it is around 7.5k to 8k.

I searched for other brands and below offer MF DIN66 batteries (including their price). Which would be my best option among them? Thanks.

3K MF 15 months - 4.6k
Panasonic MF 18 months - 5.4k
AC Delco MF 24 months - 6.5k
Amaron MF 24 months - 7.6k
