How long are batteries good for after expiration date?
| Battery Self Discharge Rates 2A: | |
|---|---|
| Battery System | Estimated self-discharge |
| Alkaline | 7-10 year shelf life, self discharge at about 2-3% per year |
| Lead-Acid | 5% per month |
| Nickel-based | 10-15% over the first 24 hours and then 10-15% every month afterwards |
