In today vehicle there are many electronic device that still draw power from the battery.

Car radio memory on station pre-set
Car radio clock
Computer/ECU to save driving parameters
Car alarm + sensors
Power seat menory

To prevent problem,I will start the engine for 5 minutes once a week.

If are in an enclose area and has access to a power outlet then it's a good idea to connect a float battery charger to keep the battery is optimal condition.

Here is a sample of float charger / battery tender.

It's on sale for $7.99 now or you can but better quality one at your local auto part store for $30+

It's a good idea to check for worn belt and weak alternator.

A belt with 60,000 or 5 years should be replace.

Check the voltage at the battery terminal after the engine is warm up for 5 minutes. The voltage should be above 13.8V

Auto supply store may provide more in-depth battery and alternator testing for free.

Please email me if you have any question.

Isuzu trooper 2002 it started shut down started then it shut off .Now i try to start it and nothing no buzz no clicking nothing,the battery is fully charged. i just bought it. can some one please help

Try disconnecting a battery cable. Reconnect 5 min later. This resets the ECM. These vehicles are a real continuing problem when they get old. I had a 1990 Trooper II and finally junked it last year.

Just press the 4wd button on the dash at any speed up to about 40mph and press again to come out .
When you turn the key on and the oil and battery lights are on the little green 4wd light should be on too if its flashing or not on check your fuses in the drivers footwell.
