2005 Solara Battery Replacement Tips...

10-25-2009, 09:53 PM
I am about to replace the battery in a 2005 Toyota Solara 4cyl.

Wondering if there is anything I should know before disconnecting the original ?

1) If I am able to reconnect to the original battery within two to five minutes, will any settings be lost ?

2) Will I need to have the dealer reprogram the key fobs ?

3) Will the security system need anything to resume working ?

4) Will the windows and sunroof need resetting ?

5) Will the radio still work or will it be locked out ?

6) Will the daytime running lamps still work properly ?

Just that I've heard about too many horror stories over something as simple as a battery replacement. There are a small handful found when searching this section of the forum; however they never seem to mention what year their vehicle is. Well aware of the basics like baking soda, cleaning the contact surfaces, etcetera.

Took off the tie-down, loosened the positive then the negative terminals and got the replacement positioned for a quick swap-out. Lifted off the negative, lifted off and covered the positive, quickly lifted out the battery, plopped down the replacement, uncovered the positive and connected it, then the negative.... and no problems. Noticed it didn't start right up on the first attempt; but no problems, really. Vehicle had no power for less than sixty seconds.

By the way I tested the alternator and:

Battery: 12.75v
Idling: 13.75v
3k RPM: 13.9v

All-in-all that's only a volt difference between completely off and running at 3k RPM but am told that is normal. With my Ford, there is a two volt difference.

Voltage is perfect, just change the battery all will be ok
