Do electric batteries in hybrid and electric batteries expire? If they do. Is there anything anywhere on the vehicles and battery that tells you that when you buy a vehicle that has a battery for a electric vehicle or hybrid?
Of course batteries degrade over time and will ultimately die completely. That's entropy for you.
They are typically rated for 10 years of service. I've read reports people who have 10 year old EV's that are still going strong. Degradation will happen but it doesn't necessarily mean the car is useless.
The following is based on personal experience with hybrid batteries, and constantly reading forums about hybrid batteries, and EV batteries.
Batteries degrade over time, with a combination of use, charging, and environment.
Constant rapid super charging will kill your battery faster. Slow charging will help your battery last longer.
Super hot weather will kill your battery faster. Super cold weather will kill your battery too. Moderate to cool weather is good battery life.
Using your car too much will kill the battery faster. Using it too little will kill the battery faster. Use it just right and it will last longer.
Heat is the enemy of batteries. It notice in hybrid battery backs that are stacked side by side, the middle modules are the ones that give out first. Probably because there is more heat in the center than in the sides. It seems like the modules on the ends have the best battery life. Probably because heat can escape on the sides.
