Lithium-Ion battery?

[caisson12]

I see Teslas parked in the railroad parking lots all the time here in Connecticut in all 4 seasons............

I wonder about those who post about issues with power drill lithium ion battery packs in cold weather.

I charged both l-ion power packs for my Milwalkee drill yesterday, stuck them in the freezer (-2 deg F), over 24 hrs and both operated fine.

when my lithium batts are in the van overnight at -25 c they won`t run unless i warm them up for 20min

The power indicator on the drill dropped to 60% when batteries where removed from the freezer, after about 5 min of running they showed 100%.

I don`t have the power indicator on my rigid drill .

Depending on discharge depth, a Lithium battery can do 5x as many cycles as lead acid. It can handle 80% depth of discharge (DOD) while lead acid handles 50%. If replacing a lead acid battery under two years old due to deep-cycling damage, you'll save in the long run switching to Lithium-ion.

If you run lith-ion below 80% it shortens their life.

which means in our -30c weather lith ion batteries would be no good cause batts loose there charge in cold weather .

They don't loose their charge in cold weather. The voltage drops. The amps are still there.

With lithium batteries being so much lighter, you can keep the voltage the same, but increase amps in the same demensions. A higher amp battery will produce a higher voltage under load compared to a battery with a lower amp rating. So it might be very well possible that a lithium car battery would perform better in colder conditions being that it has a higher voltage output due to a higher amp rating.

I'll say this. I don't believe MB would be installing these in cars if they were unusable in colder climates.

these batteries are just to new for me I guess I`m old school .I am sure MB did alot of testing on these batteries too.

Lol. Your not that old school. Your on the intraweb talking about the future of transportation advancement.
