With most phones, it is a matter of trouble: batteries stay good for a year or two and after that, you can watch in awe how goes faster to zero after your battery is ‘full’. With electric cars, that seems to be a lot better, because the batteries seem to last a lot longer than the manufacturers themselves thought and the drivers are on average also very satisfied.
A self-constructed study among Dutch-speaking Tesla owners is of course not normative for all electric car batteries, but the results of this mutual exchange of statistics are certainly hopeful: after more than 250,000 kilometers driving, the batteries have the Teslas still account for more than 90 percent of their battery capacity.
The biggest ‘fall’ that the batteries make is in the first 80,000 kilometers, but afterwards, it only slows slowly. That is reassuring, considering the fact that you want to use a car for a significantly longer time compared to a smartphone or other device with lithium-ion batteries and replacing such a large battery is not cheap.
Again, this is not scientific research of enthusiasts in a forum, but with 350 people roughly on one line, it seems to be right. Even if you have a breakdown and get a battery that does not perform like the rest, there is also a warranty on the batteries. You do not only get that at Tesla, although the guarantee is the best so far: the company promises that at least 70 percent of the battery capacity remains after 200,000 kilometers, while other manufacturers are less certain of their own business. For example, in the Nissan Leaf, you get a guarantee for two-thirds battery after 160,000 kilometers or 96 months (13 years). Still not bad, so in that respect, you do not have to worry too much about your battery as a potential electric driver.
