The runtime of a 100Ah battery depends on the load it is powering. For example, at a constant draw of 10 amps, the battery can last approximately 10 hours (100Ah / 10A). However, if the load increases to 20 amps, it will last about 5 hours. Understanding the current draw is essential for accurate runtime estimation.
Understanding Battery Capacity and Runtime
A battery’s capacity, measured in amp-hours (Ah), indicates how much energy it can store and deliver over time. A 100Ah battery is capable of providing a specific amount of current for a defined duration, making it crucial to understand how to calculate its runtime based on various loads.
1. Calculating Runtime
To determine how long a 100Ah battery will last under different loads, you can use the following formula:
Runtime hours =Battery Capacity Ah Load A
Example Scenarios
| Load (Amps) | Runtime (Hours) |
|---|---|
| 5A | 20 hours |
| 10A | 10 hours |
| 15A | 6.67 hours |
| 20A | 5 hours |
2. Factors Affecting Battery Life
While the above calculations provide a theoretical runtime, several factors can influence actual performance:
A. Depth of Discharge (DoD)
For lead-acid batteries, it’s recommended not to discharge below 50% of their capacity to prolong lifespan. Lithium batteries, however, can often be discharged up to 80-100% without damage.
B. Temperature Effects
Extreme temperatures can affect battery performance. Cold weather may reduce capacity and efficiency, while high temperatures can lead to faster degradation.
C. Battery Age and Condition
Older batteries or those that have not been maintained properly may not deliver their rated capacity, leading to shorter runtimes.
