Lithium Battery Warranty Guide: What to Look For
Lithium Battery Warranty Guide
A lithium battery warranty should state years, cycles, and end-of-warranty capacity. Vague warranties hide weak cells.
What to Check
| Term | Good sign |
|---|---|
| Years | 5-10 for LFP |
| Cycles | Number stated |
| Capacity floor | e.g., 70-80% at end |
Questions to Ask
- What capacity remains at warranty end?
- Who pays shipping on claim?
- Is the BMS covered?
