A common concern of anybody purchasing a new or used electric vehicle is the longevity of the battery as well as the costs associated with repairs or replacing it. Data collected using vehicle battery health over the past 10 years shows a decrease in battery health by about 10% over a five to six year period, however a number of factors can influence battery health degradation.
There are a number of general tips to help maintain and improve the longevity of the battery including:
Electric car batteries have a number of differences compared to a typical battery found in a laptop or phone, therefore the battery doesn't deteriorate. A phone or laptop typically contains one battery, whereas a car will contain thousands of individual batteries in packs that work together. A number of manufacturers also cover the battery with a special warranty to help alleviate some of the anxiety associated with this. The warranties vary dependant on whether the car is a plug-in hybrid (PHEV) or full electric vehicle (EV), with the EV cars typically having a longer warranty period as standard. The warranty that typically comes with an EV is 100,000 miles or 8 years (whichever comes first), however this can sometimes differ so we've created the below list:
Manufacturer | Warranty
Period
|
Audi | 100,000 miles
or 8 years; whichever comes first

BMW | 100,000 miles
or 8 years; whichever comes first

Jaguar | 100,000 miles
or 8 years; whichever comes first
