This could either be that the battery output fuse needs to be replaced, or the battery itself is faulty. Do the following:
1- On certain battery types, the output fuse is located on the outside of the shell. If you can locate it, replace the fuse. If you are unable to locate it, please do not open the shell of the battery. Instead, contact us to arrange for the fuse to be replaced by our capable technicians.
2- In the unlikely event that you have already replaced the fuse and the voltage still shows 0V, this means a deeper technical fault with the battery cells or the battery management system. Please send the battery back to us for repair/replacement:
1- Copy the link of this page from your browser. Contact us with a brief explanation and include the link of this page with your support request.
2- A technical advisor will be allocated to you and will contact you very soon. They will personally manage your case until it is resolved.
3- If your product is under warranty, our technician will provide you with a unique number and a form which you must include with the items you send back to us. Please note, you must also provide proof of purchase with any items you send back under warranty.
