Good to know before you buy
- Keep your receipt: coverage counts from the date you bought it at retail.
- You pay shipping to send the battery back.
- Charge it at least once a year and only with a lithium-compatible charger, or the warranty can be refused.
- A battery is treated as good if it still holds 70% of its original capacity.
- Defects found in the first 30 days get a refund when you return the battery.
