insurance and lithium batteries

[Robert H. Wilkinson]

An interesting article on your insurance and installing lithium batteries.

Interesting. Thanks for posting that link.

On my boat, NO batteries are left to charge overnight, (phone, tablet, camera etc.)

Unfortunately the author didn't understand the different chemistries and the risks with each. Read the "comments" for more accurate information.

The Li batteries used in boats and RV's (now are often standard or an option are the LI Fe PO4 batteries, which have minimal risks of fire or explosion. Consider the FLA batteries if abused can both explode and burn.

The Key to any battery success or failure, is the way it is installed, the way it is charged and discharged (Good Battery Management systems) and a quality battery to start with.

Risks from proper mfg, storage, handling and charging lithium batteries may be
decreasing, but, if you're unlucky enough to have a fire from one, when they're
hot, they're hot. And, even on a boat (in the water), some water around isn't much
help. Your onboard extra in a box Jabsco or Seaflow 3 GMP or even the Maxzone
1100 GPH would need some frantic assembly but then simply wouldn't do the job.

The above referenced article does not mention the Morris, IL plant fire (June 29,
2021) where some 100 tons of multiple sized lithium batteries caught fire and
burned the entire old paper plant down.

The extreme heat with explosive potential and toxic gasses make these fires
anywhere extremely dangerous. My time spent with a local FD, I witnessed my
fire fighter colleagues were not well prepared to deal with lithium battery car fires.
The batteries are hard to get to underneath the burning vehicle and, even if
extinguished, can reignite once on the tow truck. One lithium battery car fire can
tie up multiple tanker trucks supplying water, totaling thousands of gallons, to
control or extinguish the fire and often special chemicals are needed. And, it is
not unusual to not attempt to extinguish a lithium battery fire; instead evacuate
people as needed, limit the fire spread and minimize local damage.

Aye.

Yes, lithium battery fires in cars are scary and hard to deal with, but keep in mind that the current battery technology in cars is NOT LiFePO4, which is inherently safer.

While lithium-ion batteries have become the preferred battery for solar backup,
the type of lithium battery makes a difference. Goal Zero Yeti's use a lithium
nickel-manganese-cobalt-oxide (NMC) battery, while the Bluetti AC 200P uses a
lithium iron phosphate(LiFePO4 or LFP) battery.

NMC battery: older, fewer charge cycles
LFP battery: newer, safer, many more charge cycles

Then there's lithium carbonate and lithium citrate. These drugs, and others,
are prescribed to treat bi-polar (manic-depressive) disorders.

85% of the world's lithium comes from China, Australia and Chile. Interestingly,
Elon Musk tried to get his own private Li mine in NV for Tesla, maybe other uses,
but may not have been successful. On the horizon, to replace Li, is sodium.
It's much more plentiful, next to Li on the periodic table and tastes good on just
about everything.

Aye.

What Dr. Bob said - lithium ion (Li) batteries are the ones involved in the fires, not lithium iron phosphate (LiFePO4). It is incorrect to generalize that all "lithium" batteries are dangerous and would risk denial of insurance coverage.
