How does self-discharge differ among lithium and nickel-based battery chemistries?

All batteries, regardless of the chemistry or manufacturer, are affected by self-discharge. Age, cycling, and storage conditions are just a few factors that influence a battery’s self-discharge rate. Some battery chemistries are more prone to self-discharge than others. The below table summarizes the expected self-discharge rates of battery chemistries offered by HDP.

Battery Chemistry Estimated Self-Discharge
Primary Lithium-metal 10% in 5 years
Rechargeable Lithium Ion 5% in 24h, then 1 - 2% per month (plus 3% for protection circuit)
Nickel-Metal Hydride 10 - 15% in 24h, then 10 - 15% per month
Low self-discharge (LSD) Nickel Metal Hydride 15% in 1 year
