The duration a 12V 200Ah battery can last depends on the load it is powering. Generally, you can estimate the battery life using the formula:
For example, if you have a load of 100 watts, the current draw can be calculated as follows:
Using this current draw, the battery life would be:
Battery Life Based on Different Loads
Here are some examples of how long a 12V 200Ah battery might last under various loads:
| Load (Watts) | Current Draw (A) | Estimated Battery Life (Hours) |
|---|---|---|
| 50W | 4.17A | ~48 hours |
| 100W | 8.33A | ~24 hours |
| 150W | 12.5A | ~16 hours |
| 200W | 16.67A | ~12 hours |
| 300W | 25A | ~8 hours |
Factors Affecting Battery Life
- Depth of Discharge (DoD): For optimal lifespan, it’s recommended to discharge deep cycle batteries to no more than 50% of their capacity. This means that for a 200Ah battery, you should ideally use only 100Ah to extend its life.
- Efficiency: Consider the efficiency of your system. Inverters and other devices may not operate at 100% efficiency, so it’s wise to account for this when calculating battery life.
- Temperature: Battery performance can be affected by temperature; colder temperatures can reduce capacity and efficiency.
- Age and Condition: The age and condition of the battery also play a role in its performance and capacity.
