Is this a Cheap way to replace electric car batteries?

Question

I have been thinking about converting a car to an EV, but one reoccurring expensive piece are the batteries. They will have to be replaced every several years, and that is thousands of dollars alone. So, I recently bought an optima battery, and received a lifetime warranty with it. So I'm thinking, why not buy batteries that have a lifetime warranty on them, and replace them under the warranty. Even if they are prorated, shouldn't that be pretty cheap to do?

Answer 1

do you research. car batteries are a shallow cycle design, meaning that you should not take more than 10 % of the charge out of it. batteries that are used in electric vehicles are a deep cycle design and Depth of Discharge is 80 % check these sites.

Answer 2

you can use those type of batteries in an EV you make yourself, And I dont know if optima would replace your batt if they knew what you were using them for.

Answer 3

Using regular car batteries to run an electric car would void the warranty.  You could use them but you would need to basically fill every available space in the car with them.

Answer 4

Best way is to buy a large truck and a large used battery designed for use in a diesel electric submarine.

These batteries are usually sold to hospitals for emergency backup.

You can use a diesel to run the vehicle while you charge the battery.

Answer 5

I don't think they are the same batteries that electric cars use.

Answer 6

You will not be able to get very far in your electric car with those batteries.   In general electric cars don't go very far on a single charge, but they are a lot better than they used to be.  Electric cars use special types of batteries that is why those batteries are so expensive, you can not put in ordinary car batteries and expect to go very far at all, maybe to the grocery store and back but that would be about it.  Plus after a while of always returning the battery using the warranty, they will stop honouring the warranty trust me you can only cash in a few times and they will say enough is enough.  



To have an electric car you basically have to take out everything that your car has right now and rebuild it.  I think you would find you might as well just buy an electric car.  You need to have an electric motor, your current motor will not work.  Real electric cars have regenerative breaking which means that when they break they actually recharge the batteries.  You should look at the phoenix motorcars website. www.phoenixmotorcars.com and buy one of their cars, their cars have the latest technology and seem to be the best electric car company around that I can find.

Answer 7

They've already thought of that.  Read the warranty.
