2004 4runner V6 hard to start occasionally

[superrman77]

Well like the title says. My wife has had some issues with her battery being dead. Sometimes the 4runner will barely crank over. The battery is a 84 month Toyota battery from 2010. I got the battery and alternator tested at oreillys and everything tested fine. She has had to get a jump once. Every time I get in the vehicle it starts fine. She has been leaving her lights on and letting the car shut them off on her on. I told her to stop and to manually shut them off. She does have a sunroof and an aftermarket parrot for her cell phone. Where should I start?
Thanks

check the fuses, also turn off the lights before you crank. check the terminals.

Cold weather with frequents starts and not a lot of driving/recharging between those starts equals dying batteries.

She drives a lot. Car doesn't sit much

Mine does that when gas is below a quarter tank.

Where do you live and is it cold? Does it do this in the summer?

Double check the battery is the correct one for your 4 runner

The starter itself could be going bad. Sounds exactly like what happened to my 2002 4Runner when my starter went out.

Pull the terminals off and clean them, you can sand paper them. This would help make a better path for electrons to happily bounce and bump thier way to the starter. Don't put any thing on the contacting surfaces like dialectric grease.
