Truck Battery $$$$$$$$

[ACORN]

Is it in the garage unlocked? So much stuff is on 'standby' when the car isn't locked that there is quite a current draw. Modern cars need to be locked, even in the garage.

Locked or unlocked your car is constantly drawing current keep various things like radio station presets, clock, computerized engine control systems, uh, set. If the car is run regularly, you never notice the drain as the charging system re-charges it but if a car sits too long the battery goes dead.

My wife's 2009 Kia Borrego failed to start for the second time in two weeks this afternoon. The sticker on the battery is 6/19 (June of 2019).
Both times that it didn't start, it had sat for a couple of days and a quick "jolt" from a jump-starter revived it.
Guess it is time for me to go get a new battery tomorrow <sigh>.

You might try giving it a good charge.
Modern chargers do recharge a battery like the old generator systems.
But at 5 years old it's getting towards of the average life span.
There are exceptions though.
My Dad had a Crown Vic that had the factory battery that lasted 11 years.

I just had to replace the original battery in my 2017 Mustang. Seeings as I was a parts manager for 34 years I never paid much more then $100 for a top of the line Interstate battery. Now that I'm clear across the country without my former connections, this one cost $220!

Batteries prices are insane. When I lived in Las Vegas, NV. I
would always pop the hood after a drive when I parked my
vehicles in the garage. Of course the garage got hotter, but
letting the heat dissipate from the engine area helps to prolong
the life of the battery, plastic and rubber items.

I have a 2010 Tacoma SR5 Extended cab truck. I bought
a new 6 year Toyota factory battery for it back in 2016. I
moved to SW Utah in 2018. I popped the hood when I parked
it in my garage. I had to replace that battery in 2022. It lasted
6 years and one month.

Yeah, it got a good recharge both times it went dead. The alternator was putting out 14.4 volts and an hour or two of running the car with the alternator putting out that voltage should have charged it up adequately.

Like I said, it had a charge of 12.4 volts when they hooked it up to the load tester. But when the guy flipped the switch to start the actual load test it immediately dropped to 8.6 volts - when their chart said it should show a minimum of 9.6 volts when under load. And it continued to drop steadily and rapidly as the load test continued.

No question that it was bad. It would charge up to full 12.4 volts, it just wouldn't hold that level of charge for more than a couple of days, and the voltage was dropping by 1/3 just as soon as a load was put on it.
