Eventually electric bike batteries need to be replaced as their lifecycle comes to an end.
You can tell when a battery is nearing the end of its life when it does not provide you with much range.
This guide will help you with ideas on how to get a replacement electric bike battery.
First of all, if you have a complete electric bike you should buy the replacement battery from that e-bike company. Typically you can get a replacement from your local dealer but in some cases you may need to contact the e-bike company directly.
The same goes for electric bike kits. Always check with the electric bike kit company for replacement batteries for their products.
If the company is no longer in business or they are not supplying replacement batteries then the following ideas for replacement batteries may be helpful.
Please note that using one of these replacement batteries may void the warranty of your complete electric bike or kit. Check with the e-bike or kit company to understand what their policy is regarding the use of aftermarket replacement batteries.
If you use one of these batteries you will need to make sure its specs will work with the complete e-bike or kit that you have.
Also, you or your local electric bike shop may need to create some custom wiring connections and/or battery case connections in order for the battery to work on your bike.
Okay, I believe that was enough warnings, here are the replacement battery ideas.

Your Local E-Bike Shop:
Check with your local shop to see if they have replacement batteries in stock or if they can order you one.
NYCEWheels is an electric bike shop in New York City and they have been in the e-bike business for a long time. They have a healthy selection of replacement batteries that can be found here.
NTS Works Rebuildable Batteries:
NTS Works has developed a rebuildable lithium Universal Battery. With their technology they are able to install install new cells (Samsung cells) while reusing the original battery case.
They claim that the battery rebuild is half the cost of buying a whole new battery.
This can also mean an increase in range as most cells increase in capacity as the cell technology improves.
In addition, the case is built tough to withstand impacts and it is waterproof.
Here is more information on the NTS Works Universal Battery.
In addition to the Universal Battery, they have also developed their Mini 48V Mini lithium battery.
This is a 48V 9ah lithium battery that weighs 5.5 pounds!
It is also rebuildable and built tough like their Universal Battery.
