I have a lithium battery that either needs to be replaced or repaired. The performance has noticeably declined, and I'm looking for a reliable solution as soon as possible. Could you provide details on your services for battery replacement or repair? Please let me know about the estimated turnaround time and any associated costs. If possible, I'd also like to understand your warranty policy for the replaced or repaired batteries. Looking forward to your prompt response!
