Starting voltage

My five year Optima Red Top has been flawless. Truck has the alternator + .5volt tune on OTT since day one. When I push the start button after sitting all night this display in the 12v port reads anywhere from 11.7-12.1v until the truck fires. It literally takes a second to turn over then displays 14.2v.
Knowing enuf about running an offgrid fish camp in Baja it seems like 12.2 or less is only around 25% charge. 11.7 should be dead!
Am I on borrowed time with this battery or MORE IMPORTANTLY how does the push to start act when you get a battery that is ready to die? Does it labor to start like the old school cars 25 years ago?
Next trip in two weeks and don’t need the hassle of a dead battery! LOL

 

I could be wrong but i would think that whether it is push to start or turn key, a dying battery would still show the same symptoms.
Keep a NOCO on hand and/or maybe a new battery that's ready to swap out?

 

Makes sense, I guess. Looking for someone who has experienced a dying battery and can confirm symptoms. NOCO sounds interesting! How many jumps on a full charge?

 

I haven't had to use mine yet but the web says a

$92 NOCO GB40 : 1000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 6.0L Gas and 3.0L Diesel Engines

NOCO GB40 can do 20 jumps from a full charge.

 

My factory battery developed a bad cell at 33 months into my warranty. It would labor to start and eventually not turn over and just click.

Toyota gave me a free new TrueStart battery which is coming up on 7 years. I know I could just buy a new battery but want to see when it dies. I do carry my jump box in my truck at all time. I am old school so I like lead acid and know it will fire up my truck when needed.

I think that seems high. I have 3 of them, and not had to use it on my Tacoma but have on 4Runner and Outback, and use the Tacoma one on a SxS for 5-6 times. I don’t remember how low the indicator got but I do try and timber to charge them every six months.

I think they are a good buy.

 

Thanks lads.
