To determine whether your 12V battery is an AGM (Absorbent Glass Mat) or a lithium battery, you can follow these steps:
1. Check the Label and Specifications
- Look for Markings: Most batteries have labels that clearly indicate the type. If it says “AGM” or “Lithium” (often specified as LiFePO4 for lithium iron phosphate), that’s your answer.
- Specifications: Review the battery specifications, which are often included on the label or in the user manual. Lithium batteries typically list higher cycle life and depth of discharge percentages.
2. Examine Physical Characteristics
- Weight: AGM batteries are generally heavier than lithium batteries. If your battery feels significantly lighter for its size, it is likely lithium.
- Size and Shape: While both types can come in similar sizes, lithium batteries often have a more compact design compared to AGM.
3. Charging Characteristics
- Charging Voltage: AGM batteries usually charge at around 14.4V to 14.8V, while lithium batteries charge at a maximum of about 14.6V to 14.8V but may have different charging profiles.
- Charge Time: Lithium batteries typically charge faster than AGM batteries. If your battery charges significantly quicker, it may be lithium.
4. Performance Metrics
- Depth of Discharge (DoD): Lithium batteries can usually be discharged up to 90-100% of their capacity without damage, while AGM batteries should not be discharged below 50-80% to avoid shortening their lifespan.
- Cycle Life: Lithium batteries often have a cycle life exceeding 2000 cycles, while AGM batteries typically last around 400-500 cycles.
5. Consult Documentation
If you still have the documentation that came with the battery, it should specify whether it is AGM or lithium. This information can also be found on the manufacturer’s website if you have the model number.
6. Ask an Expert
If you are still unsure, consider consulting with a battery specialist or contacting the manufacturer directly for clarification.
