The interstate 850CCA battery on my Ford E-350 XLT Super Duty 5.4L is completely shot beyond jump starting. I need to go out and get a new one...
The current one is 850 CCA, and Napa claims that a Napa brand 675CCA is 'good' for my 5.4, a Napa brand 750CCA is 'better', a triple-a 750CCA is 'best', and an Oddesy 950CCA is 'extreme'.
Do I need another 850 or is it overkill? I want a reliable battery but don't want to spend pointless money.
If I do need an 850, I look at Walmart and F&H Supply (Basically a local chain Rural King) and I can get lower end 850CCA for $80-90, which is the route i'll go if I really need an 850.
For reference, here are my choices on 850 batteries:
Thanks for any recomendations. Trying to be thrifty but also not get stranded in a year down the road.
Be careful because there is trade-off with batteries. To increase the crank current, a battery has to have more surface area on the lead plates. To get more surface area, you have to make the plates thinner so you can fit more in there. The thinner the plates are, the less reserve capacity, and the sooner the battery will fail (from dendrites, and plain disintegration)
I would find out what the OEM battery spec is and use that. You only need to get more cold-cranking-amps if (as the name implies) you live in a cold climate.
I would choose a 850 CCA battery. You have a big engine and you need enough juice to crank. The price is good on Walmart too.
