Battery purchase mistake?

Peoples

Please look at that photo closely, and imagine if you can read the entire label.

It says Platinum, not Lithium.

It takes hours to fully recharge a dead-dead battery, if it can be recharged. Driving any car will not ever fully charge a lead-acid battery, even if going 70 miles an hour for hours. If it could, it would over-charge any battery, as it never stops supplying 14v DC (nominal) auxiliary power.

You did not make a mistake in replacing that battery, due to age and it being so readily killed.

I strongly recommend that you invest in a 4-amp charger from Harbor Freight that has an AGM setting option.
Do fully charge your new battery - it was not fully charged when you bought it. It is the best thing you can do for your Aux Battery to extend it's life.

I full charge my Aux battery about once a month - whether it needs it or not

The entire Optima product line is a spiral-wound AGM lead-acid technology. IMHO, you can't do any better than that. I had a blue-top that lasted over ten years, with regular maintenance full-charge cycles, and a good portion of that time was in a gas-powered golf cart. I can't think of a more severe service condition.

I am jealous that you have one that fits, and look forward to replacing my 5 year-old OEM battery when the budget allows.

?? According to post #13, there's an "AGM Technology" battery in the car already. What "poisoness" gas do you imagine it will emit?

My non-oem $65 AGM is at 8¼ years and still kicking.

 

that's not lithium, the spelling makes it look like it, but it's the battery model name.
lots of people here have optima replacement batteries. as long as it is agm, has the vent tube connection, and fits properly, you'll be fine.

although you understand lithium to be superior, most cars come with lead acid

 

??? I didn't see that there was an agm battery there.
Gases from the chemicals in the lead acid battery from charging and discharging...

 

it's says it on the battery in the picture he posted.

looks like

'platinum'
'agm technology'

 

After copying the photo, and Zooming in, I finally saw it! But that is not what I was talking about.
I was commenting on this....

See post #19
... I eventually bought a lead acid optima battery from Amazon but not sure if I should swap it now that it just dawned on me I got a lead acid as opposed to the current lithium....
You think I’ll be ok with the lead acid optima and just install it without obsessing with lithium type that came with mine originally?

 

i have read that our batteries are lead/acid. but absorbed glass mat, not flooded

 

???

 

what's the question?

agm-battery

 

A correctly functioning alternator/regulator will NOT overcharge a battery.
As it gets closer to a full charge, the less amperage it supplies.
It will show 12 volts, but will only be enough amps to run the components and keep
the battery topped off.

 

This is true

This is not entirely true. Yes, as it gets closer to a full charge the less amperes the battery draws.
But unless a vehicle has an aftermarket system, there aren't any I know of that provide a smart charger. Therefore, without an external charger, the battery never gets topped off.

No vehicle that uses a 12 volt (nominal) system 'shows' 12 volts, unless something is wrong.

 

Your understanding of a Toyota hybrid charging system is wrong. It does everything a smart charger does and more.

 

"hybrid charging system",
or 12volt auxiliary system (which is what I am talking about).

 

I am sorry, my point was , it will be something higher than 12.7 volts to maintain the charge in any car.

 

It draws less, and the alternator puts out less...

None of the systems show 12volts, it is alway over that amount.
Alternators put out 13-14 volts. The voltage must be over what the battery is (12.x volts)
or it won't charge it.
That's pretty smart!

The inverter/converter on the Prius would pretty much do the same thing.
And I think it's actually higher voltage than an alternator. I believe it is supplying
less amperage than an alternator. It wouldn't send 90+ amps to the battery.

 

Too long to read syndrome.

 

It looks like a aftermarket battery to me..
A "Platinum battery".
