matching batteries

[the_big_fact_hunt]

Do they have to be the same rating? just swapped one on my other van under warranty and they gave me the next size up, 110 instead of 100, think its 5A more powerful, was going to put it on my mk7 jumbo with twin batteries. instead of letting it go when the older jumbo sells

My arsewash 3000 has 2 different amp batteries
All good, perfect, drink from furry goblet

Capacity does not matter, age and wear does. Mixing old and new is a great way to kill new batteries.

I swapped a battery on my twin battery mk7 jumbo not long after buying the van and never bought another.
I sold it 4 years later.

Buying 2 new batteries when 1 is still good is a great way to waste money

Looks like my last three vans have been lucky. As was my mates stu’s van

My knowledge is from my experience.

ive been a mechanic for a fair while and now re trained as a electrician
please explain why batteries should be replaced as a matched pair
even fords dont replace them both at the same time if only 1 is at fault

[bigjohnthomas]

I would think its like a pack of lipo batteries where you balance charge them
Or the weak cell gets fried and the good cell gets undercharged
But its not as if 2x 12volt batteries have 12 individual cells or enithink init
