Biggest battery that I can get

I have a 2002 ford ranger edge. Will this fit my 2002 ford ranger edge?

2002 Ranger with 3.0l or 4.0l uses Battery Group 59

Battery group is the height, width, and length of battery and where terminals are locate(top or side) and + and -

So is that battery a Group 59?
Should be on it somewhere

Size in inches for Group numbers here: https://www.jegs.com/Sizecharts/bcigroup.html

So if that battery is the same size or slightly smaller then it should fit
Check to make sure + and - cables will reach correct terminals

Ranger V6 engines use 550CCA(cold cranking amps)

Anything more doesn't help much

Battery is ONLY USED to start the engine, doesn't do anything at all after engine is running, alternator powers everything
Batteries are only a max of 13volts, Alternators MINIMUM Voltage is 13.5volts, so battery is off line, it absorbs voltage to stay charged.

If you want longer lasting power with engine off, then look at adding a smaller 12volt Deep Cycle Battery in the engine bay, they are made for long steady drains, which kill car batterys which are made for quick discharge and recharge, not long drains

If you need more AMPs for lights or audio gear then go for bigger alternator

Having lived most of my life in Alaska I always bought the biggest, highest cranking amp battery that would fit. In one car I had I put a battery in parallel for better cranking. Try starting a car at -45 or colder with a small battery. Most batteries lose half their CCA at 0 F so at -45F there just is not much juice there. Good ahead and buy the big battery as long as it fits.

Yes, in extreme cold a batteries chemical reaction to release AMPs quickly slows way down, plus colder engine takes more AMPs to crank, so double whammy

But poster is the Georgia.............so not likely to run into that extreme cold, but spending the extra money on more CCA is always users choice, battery in picture shows 615CCA, so about 10% more than standard 550CCA, if price is right it certainly won't hurt, but he never said the reason he wants more "battery" than stock, and that matters

I already have the battery just wanted to know if it was safe to use.

If it will fit in the tray and can be secured, and the terminals are in the right location, and terminals will not touch the hood when it's closed, then yes it's safe.
