Recently bought a replacement battery for family members Car. Noticed Lithium Batteries were offered.

NUTS! I know of vessels catching on fire due to Lithium Car Batteries. I know a fireman and he told me it takes an incredible amount of water to put them out.
He said he would never put one in his car. He is a "Car Guy" too.

Please seriously consider the pros and cons before buying your battery.

Yikes, yea would definitely never use one in a car.

You don’t say?

How about showing off your newly released state of the art electric zero turn mower only to burst into flames AT A TRADE SHOW!

Lithium...it's not just for breakfast any more...

That's very strange. Usually EV cars still have a 12v lead acid battery in addition to the high voltage lithium battery. Also, a lithium battery would be a very bad idea for a 12v in a standard gas car. Lead acid batteries have different use cases than lithium. Lead acid batteries can remain on charge and can be discharged almost completely without damaging them. Lead acid is also better at handling a sudden burst of power draw without heating up as much. Lithium batteries are better with regards to weight and size relative to the amount of power that they can store, but they need to be carefully maintained with regards to charge cycles to avoid damage and reduced battery life. Also, a lithium battery drained to 0 volts will never hold a charge again.

If you have enormous power requirements like in an EV, the complex charging requirements of lithium is a reasonable trade off for the sake of having a smaller battery with a longer lasting charge.

For a combustion vehicle, having a slightly weaker and slightly heavier battery that can handle more abuse from the sudden draw requirements of a starter motor, lead acid makes more sence. Your alternator and starter motor will not be kind to a lithium battery, and it will not last long as a result.

On a related note, a local fire Lt. was giving a safety talk yesterday, and he brought up lithium batteries. Don't let them freeze, example: unheated garage, (or as I sometimes do, in my van for work) He specifically mentioned cheap Chinese hoverboards that a local family had bought for their kids for Christmas, bursting into flames. Don't know if this can happen to our tool/equipment batteries, but I'm not willing to find out, another good reason that I keep my workshop heated to 55 degrees.

I would think if it were to happen I’d have surely had a bad day by now with all the Dewalt and Milwaukee batteries I have in my van and my garage. That’s got to be around 20 possibilities per day, a few months a year, and well over five years for my Lithiums.

Yup, I’m playing with fire…

Just think insurance Ken! [emoji1303]

They used better quality lithium 5 years ago as opposed to the lithium used today...:D :burnout:

I know of several instances of barges that caught on fire due to lithium batteries in the metal scrap. To put it out they had to sink the barges.

Like Rocs said, lithium is not good as a starter battery. They have 0 CCA. AGM type lead-acid batteries are the current hotness for starter batteries.

0 CCA? I guess I am ignorant. I thought CCA's were good?

CCA = Copper Clad Aluminum. Not as conductive as OFC = Oxygen Free Copper. CCA also tends to heat up when more than adequate current (for it's size and thread count) is pushed through it.

Haha, that is true, Peace2Peep, but in this case I meant Cold Cranking Amps. I meant that when a lithium battery gets cold it's output amps goes way the hell down, and if cold enough, it will be zero, also they can't be charged when cold. It will never crank an engine over on a below freezing day. That is why you see lithium batteries for big sound systems in cars but not for starting the engine. That is why EVs actually have little heat pumps (just like the kind for a house) that way they can heat up or cool down the battery as needed. (and they still have a 12v lead-acid battery as well).

That reminds me I better pull all the tool batteries out of my trunk in the pouring rain tomorrow before the temp zooms down.

Crap! The dozen or more in my garage have been exposed to as low as -25* Actual every winter for 12+ years... :eek:

Same. No plans to change now! Besides, I work outside quite often, so there’s 8-10 hours of exposure already.
