How long is the warranty period of Tailing electric vehicle batteries?
The difference between the 2-year warranty of large lithium battery merchants and the 5-year warranty of small ones traders:

2. The 5-year warranty for small lithium battery businesses is due tofact that various elements were once highly toxic materials, which can extend the life of the battery, but cause great environmental pollution. .
The battery warranty is 12 months and above.
1. The warranty period for tailing electric vehicle lead-acid batteries is 12 months.
