How Long Will a 12V 100Ah Lithium Battery Last?

The duration a 12V 100Ah lithium battery will last depends on the load connected to it. To estimate the runtime, you can use the formula:

Example Calculations

1. For a 10 Amp Load:
   • Run Time = $=10$ hours
2. For a 20 Amp Load:
   • Run Time = 100Ah/20A​=5 hours
3. For a 5 Amp Load:
   • Run Time = 100Ah/5A​=20 hours

Factors Affecting Battery Life

1. Depth of Discharge (DoD): Lithium batteries perform best when not fully discharged. Keeping the DoD below 80% can extend battery life and performance.
2. Temperature: Extreme temperatures can affect capacity and efficiency. A lithium battery may provide less power in very cold conditions.
3. Battery Condition: New batteries will perform better than older ones, which may have reduced capacity due to wear and tear.
4. Self-Discharge Rate: Lithium batteries have a low self-discharge rate, typically around 2% per month, which means they hold their charge well when not in use.

Typical Lifespan

• A 12V 100Ah lithium battery generally has a lifespan of about 2 to 3 years, depending on usage patterns and conditions, with some high-quality models lasting up to 10 years with proper care.
