Make sure its terminal connections are clean, snug and protected from the elements.
Corrosion on the battery terminals can block the flow of
electricity through the battery. That can cause the starter to have to pull
more amps to crank the engine over and cause
the alternator to have to work harder to charge the battery. Corroded
terminals will also prevent the battery
from being charged by the alternator. If
the terminals are corroded, you can clean
them with a wire brush dipped in baking soda and water, plan water, coke-a-cola
or an over the counter battery cleaner.
Now, check the
battery cable ends. A loose battery cable does an excellent impersonation of a dead
battery. If there is any movement of the battery cable end that is attached to
the terminal, it is too loose and needs tightening.
Before cleaning the connections or removing the battery,
disconnect the negative terminal first whenever you disconnect the battery
cables from the terminals. Removing the
positive connector can cause a spark. That
spark can cause a fuse to blow, and in
some cases, it can cause the battery to

the brackets that hold your battery in place are tight.
Loose brackets will cause the battery to vibrate when the car is running, and this constant vibration will shorten the life of the battery. It's also wise to check the condition of the battery tray for corrosion. Corrosion over time can weaken the tray cause the battery to be loose. If there's minor corrosion just clean it off with water. If corrosion has weakened the tray then it should be replaced. The condition of the tray and brackets is vital to keeping the battery from tipping over under the hood – a rare, but not unheard of mishap. A secure tray can also prevent excessive vibrations from damaging the battery.

your battery stays charged up.

Signs its time
to replace the battery.
If you keep getting corrosion
on the battery terminals that can be a sign that there is more resistance in
the battery and it's not taking a good
charge. Also if you see corrosion on the
battery itself or it looks wet,
then the battery could be leaking acid and should be replaced.
Also, remember the age
of the battery. A good battery should
last four years or longer. When a battery
gets old though the lead plates inside get weak and can break if hit hard
enough. At that time you have a dead
