Kind of nebulous, but I'll impart some battery wisdom...
You want to have at least #4 AWG cables for a 4 or 6 cylinder
engine, and #2 minimum for a small V8, and #1/0 for a large V8 (460).
Some import cables are all plastic and no copper. And when starting
you need to minimize the voltage drop in the cables.
Change the ground cable too - the circuit forms a loop, and that
power has to get back to the battery.
Try to stay with a major manufacturer - even though everything is
made overseas nowadays, there are vast quality differences. The
No-Name stuff can be worse than useless, because you wasted the effort
to install them.
Get a battery terminal toolkit together - post and terminal brush,
terminal spreader pliers, terminal lifter, etc. You have to treat the
terminals gently or you wreck them, they won't take a lot of abuse -
if you find yourself using a screwdriver as a pry bar, STOP.
Make sure the problem is really bad battery cables. Batteries go
bad just from old age, so if the battery is out of warranty (5 year
old "60 Month") it's suspect, especially if nobody has kept the water
level in the acid inside topped off. Have it load tested.
Oh, and the term "Maintenance Free Battery" is a big steaming lie.
They still liberate a little of the water from the battery acid during
charging and require a top-off with distilled water, just not nearly
as often - if you fill your battery once a year, you can get an extra
year or two of service life...
If you leave your battery sealed (never refill it) it will last most
of the way through the warranty period. Once the acid level drops
below the top of the plates the exposed lead dries out and starts to
sulfate, and it's all over - refilling it now won't help. Then it
dies and they get you back earlier to buy another one - the prorated
warranty is simply a customer retention tool so you buy the same brand
Use corrosion preventative coating under the terminal, and over when
done. And the felt washers where you can. It does help keep the acid
out of the contact patch between battery post and the cable.
SAFETY: At a minimum, wear safety goggles and disposable rubber
gloves when working on a battery. They occasionally blow the top off
if there is a hydrogen explosion inside - it's not a very vigorous
explosion, but just enough to splash battery acid around, and your
eyes are precious.
