Transcripts
recently I surpassed 120 000 miles on my
2018 Tesla Model 3 that means the good
news is I've saved tens of thousands of
dollars by not buying gas or oil over
the last five years but if you're
familiar with Tesla's warranty then
you'll know that the bad news is my
battery warranty has expired yes driving
an electric vehicle with an expired
battery warranty is sort of like
swimming in the ocean statistically
you're probably going to be fine but
there's always that fear in the back of
your mind that a shark might rip your
leg off sorry I have a weird phobia of
sharks but you get my point and this
analogy the shark is the possibility of
the battery dying and needing replaced
which is probably the biggest fear of
people who are hesitant to buy an
electric vehicle in fact in my recent
video where I shared my total cost of
Tesla ownership after five years the
most popular comment I got from people
who are critical of EVS said something
like just wait until you have to pay
twenty thousand dollars to replace your
battery or why didn't you account for
the cost of battery replacement and I
totally understand why people would have
this fear but based on Tesla's 2022
impact report they think it's a
non-issue by showing that even after 200
000 miles their batteries only lose an
average of 12 of their capacity well
let's find out if this is actually a
legitimate concern by using my Tesla
Model 3 as a real life test and when I
first got my model 3 the estimated range
on a full charge was 310 miles but we
all know that batteries degrade over
time and hold less charge after a
certain amount of Cycles I'm sure you
have experienced this yourself with a
smartphone tablet or laptop but the
Lithium-ion batteries in electric
vehicles are not the same and are not
used the same as those in mobile devices
the chemistry is different allowing for
more cycles and longer life EVS also
have thermal management systems that
ensure stable operation in optimal
conditions and when it comes to electric
vehicles the battery is by far the most
important and most expensive component
of the car if an electric vehicle were
in NBA team the battery would be Michael
Jordan the bottom line is that you
definitely do not want something to go
wrong with the vehicle battery
fortunately for us owners Tesla has a
really good battery warranty which
covers the battery and drive unit on a
Long Range model 3 such as mine for a
period of eight years or 120 000 miles
whichever comes first and this assures
that the battery will have at least 70
percent retention of capacity over the
warranty period so if my Tesla battery
had below 70 retention when it hit 120
000 miles then it would be eligible to
be replaced under the warranty but how
do we determine the battery health other
than estimated range well today's
sponsor recurrent is a fantastic way to
do that recurrent is a free software
tool that generates battery performance
reports to give you confidence during EV
ownership it currently supports over 50
electric vehicles and all it takes is
two weeks of battery data to begin
providing a free monthly EV owner
insights report that analyzes daily
battery data and Compares it to
thousands of similar vehicles to give
helpful insights on the vehicle's range
and charging now my model 3 Falls almost
exactly on the average of expected range
for a used 2018 version but it ranks in
the 99th percentile in terms of odometer
this proves a very important point from
their research that odometer mileage is
not directly correlated with battery
health and range if I took my model 3 to
a normal dealership they devalue the car
for the high odometer but a convenient
benefit of recurrent is their cell
feature which connects EB owners to EV
specialist dealerships who make offers
based on the battery and range data that
is validated by recurrent it's an
amazing free resource so click the link
below to connect your EV or check buyer
offers in minutes so using an app like
that is one way to track battery health
another way is to do an actual real
world driving test by charging to 100
and then driving at a relatively slow
steady speed until the battery dies and
see how many kilowatt hours the car used
but there's also an even more official
battery health test from within the car
itself which I'm going to do right now
we are here in my Tesla Model 3 we're
going to do the official battery health
test by hacking into the service menu
let's see if we can get this thing to
work to enter the hidden service menu
we're going to tap the car icon go into
the service or I'm sorry the software
and then hold down the model 3
so in here we're going to type in
service as the service code it says
service mode should only be enabled by
service Personnel to service or repair
stationary vehicle are you sure you want
to enable service mode caution do not
enable service on public rows okay so at
your own risk I'm going to go ahead and
hit enable now we have the red service
around the screen here now we're just
going to tap on high voltage to go into
the high voltage battery and tap high
voltage system
and here we have the health test for our
battery so tap on that to authorize hold
fully up on turnstock plus break plus
key for 10 seconds
unlocking
and unlocked okay so now we do Health
test
so testimate take up to 24 hours so if
you can do this make sure you don't have
to go anywhere for 24 hours high voltage
battery will be discharged and then
charge the full heat will be generated
outside the vehicle during discharge
okay
and now the health test has begun and
we'll come back to this after it's done
to get an official Health test from the
Tesla Service menu okay it's been 24
hours now almost and the test is finally
complete do you have any guesses of what
the results are I was surprised by this
seven percent wow
that's what it says battery health seven
percent so that's way lower than I
expected but what does that exactly mean
like is it is the battery approaching
end of life you know because I'm still
getting estimated range of pretty good
of two around 280 miles which is around
you know 90 of the estimated range of
when I first got the car so the battery
capacity as far as estimated mileage is
is still relatively really good
but the battery health
seems pretty bad any Tesla technicians
out there should I be concerned battery
health seven percent that's really low
should I sell the car now or should I
keep it and risk it you know uh the
battery health is probably not going to
improve right so it can only go downhill
from here for my personal situation I
guess it comes down to should I just
keep the car and just drive it as long
as possible until maybe the battery
needs to replace or will the battery
ever need to be replaced you know can it
can it survive another 107 000 miles
with just a battery health of seven
percent okay what if I lose another 20
30 miles of estimated range and I'm down
to 250 miles of estimated range in
another five years well that's still
pretty good because there are new
electric vehicles coming out right now
in 2023 that have 250 miles or even less
than that just think a 10 year old model
3
has will have the same amount of
estimated range 250 miles plus access to
all the supercharger stations which will
definitely be a lot more five years from
now so I think it's worth it just to
keep the car that was my plan I want to
keep this car for at least 10 years I
think it'll last me that long but you
know doing this battery health test kind
of raised some red flags for me so my
best guess is that this seven percent
battery health is either a bug in this
particular version of the test or I
didn't perform it correctly or the
percentage has some other mini tied to
it if we assume the worst case scenario
that one or more of the battery modules
is indeed close to failing then that
means I should expect to have a pricey
battery replacement in my near future
the model 3 has four battery modules
that Elon said costs around five to
seven thousand dollars per module but he
said this back in 2019. however even if
Just One battery module goes bad Tesla
still replaces the entire pack because
they want to be sure that the battery
has 100 health and they can't really do
that when they mix and match modules at
the service centers instead they send
the old battery packs to their battery
plants to be refurbished now according
to a Tesla invoice from 2020 shared by
current Automotive a complete 75
kilowatt hour battery replacement for a
model 3 called 16 550 which came to be
about 2300 in labor and 14 250 in Parts
with the actual battery costing 13 500.
that's quite an expensive repair but
I've always been adamant that I probably
won't ever have to do a replacement on
my model 3 battery based on my estimated
range so far which has been quite
impressive I try to follow healthy
charging Habits by avoiding
supercharging and charging mostly at
home and only charging to 80 for daily
driving and also rarely going below 20
state of charge and recurrence says my
model 3 has an excellent range score of
93 and my expected range is around 280
miles which is only about 10 percent
degradation so far after 120 000 miles
I'm going to take the risk and keep
driving my model 3 but what would you do
in in this situation let me know in the
comments below thank you so much for
watching my name is Andy if you want
more Tesla in Tech videos in the future
be sure to subscribe give this video a
thumbs up if you enjoyed it I'll talk to
you in the next one
