1998 Camry won't hold a charge
 

I have almost exactly the same problem as the person in this thread:
http://https://www.camryforums.com/f...-charge-47244/

The only thing different is the age of the car and the fact that its been sitting for about a month now due to circumstance. I'm wondering if I can follow the same advice from that thread, or if the age difference would make the process a bit different. Its had a new alternator and battery installed, a month ago, but it crapped out the next day and wouldn't hold a charge after being jumped.

Can not open the link to the other post. Is this the post by member "the desolate one?"

A battery in good condition and fully charged sitting a month should not cause issues of dead battery.

Read up on issues of parasitic battery drain, battery voltage indications when charging and at rest, etc.

For parasitic drain. Connect a milliamp meter between the battery terminal and battery cable after the car has sat for approx 30 minutes with all electrical items off.

With all items off, doors closed, etc. the current shown in the meter should be around 25 ma or less.

It has happened a trunk light fails to turn off. Defective car alarm and remote door lock systems (typically aftermarket types) can cause heavy drain when engine off. On some Camry years the remote door lock system was causing a drain but yours should not be one of them.

If the parasitic drain is too high. Start removing fuses until it drops to "normal."

To check for charging voltages. Start engine and run a approx 2000 rpm. Check voltage at the battery. The alternator should increase the voltage to something like 13.8-14.2v when charging.

A charged battery will have a voltage after resting (sitting for say 30 minutes engine off) of approx 12.7v.

Agree with Joey.
