Battery Exide or OEM FORD
Even in the colder weather now, I'd be getting 400+ km on a full charge in my BEV (Mustang Mach e). But I only charge once a week (Fri night), to 80% to help with battery life; costs about $3 per week to get an extra 200-300km.
IMHO, Exide works well till the last second and then dies off without any symptoms. Amaron shows alot of symptoms like extra cranking and lights dim for interior and dash lights when it's nearing its demise. Hence I moved to amaron. So should you.
After reading all replies and knowing the price of the dealers option, I took my chance with a Exide battery AGM 12-23, it was a perfect fit.
I don't think they are good at inverters, but I have used their battery for ups which lasted 4 years, now i am using the second one which completed one year
VW lists 3 batteries, 1 AGM (68 Ah, Varta) and 2 flooded (72 Ah, Varta and 59 Ah, Exide) that may be used.
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.
This one looks like it’s in very good shape, I’ve seen similar for sale for $200 to $300 but the couple I’ve seen at auction sold for $80 and $110 if my memory is correct. Both where in much worse shape than yours.
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.
Left with exide crap.
However, I have had nothing but bad experiences with Exide batteries. I've bought three, and all have died within 2 years.
