Just clean the cables & surface with baking soda & water then see if it happens again....

It's possible they might have spilled some acid if they had to activate the battery.....

Have the installing shop check it out....

7,000 seems high for a battery....My last 5 year battery for a diesel SUV was 4,000.....

According to battery expert
"Mr Google"

Voltage from the rectifier/charger circuit could be as high as 14.8 volts DC while recharging a 12v lead acid battery to full.
Once the battery has attained full charge voltage should drop to
13.0 - 13.8 v to float or trickle charge which keeps the charge up and reduce sulphation.

The battery once fully charged
and engine not running should read between 12.6 and 12.8 volts

Is that a battery charger or what the alternator does...?

Its new Fortuner TRD around 1 year old.
1 battery died, went flat after 1 year. So changed instead charging it.
New one cost me like say 7k
2 months later got that mess.
I only use dvr camera and sometimes charge phone. Dont think I strech electrics so much.
Its on guarantee so might claim it.

Maybe said before but obviously get Toyota to check the ECU charging system under your warranty.

Then you can address the battery if it is an issue.

7,000 battery whow !!!  you can get nearly 3 GS heavy duty batteries for that and every GS l've had has lasted over 5 years.

I don't know...I'm not the expert

I can tell you that in my long motoring carrier alternators charge off idle at around 13.6/9..That figure is constant because the alternator has a voltage regulator to provide that figure at any rpm. If the regulator has a fault (regulator) and charges way higher it will stuff/cook the battery....

Ok that makes sense for a purely (dumb) alternator/regulator charging circuit,
don't modern vehicles have a more "intelligent" charging system ?

Xaos,

 

Three votes for baking soda. Did you clean it yet

Dunno, could be.....But a battery is just a box with a required 12.6 volts to work everything, the alternator just puts volts/amps back into the box...

Did battery test.

Toyota said come back they will clean it and change some seal.

Looks like a print out from the same type of hand-held battery tester that Ford uses. It fails to detect their sh!ite batteries as well.

 
My Ford Ranger 4d, 4x4, 2.5 turbo diesel will be 16 years old in December and still runs well after 362,xxx km and I can still get parts for it. I had the clutch replaced last month for the first time.
 
In its time it has been the family car, builders truck carrying materials to build the house, pickup truck, minibus and at one point I put a 1,300 litre water tank on the back along with a Honda engined water pump and used it as a water tanker during a drought.
 
If I had the money to spare I would buy a new Ford Ranger 2.2 auto tomorrow. That would probably last until 2033 when I will be 89 years old.
 
Ford Ranger owner and proud of it.

You're no fun!

How are the Turdota buyers supposed to make themselves feel better about buying an inferior product with tales like that?
