Buying Guide
- Battery size and chemistry: Ensure the 3.2V LiFePO4 format matches your fixture’s slot, with 18500 versus AA sizing depending on device design.
- Capacity vs. runtime: Higher mAh (like 1000mAh) generally provides longer run times per night, but check the device’s voltage and current draw to estimate actual performance.
- Cycle life: Many options advertise up to 1500 cycles. Consider how often you replace batteries to gauge long-term cost savings.
- Self-discharge: Batteries with low self-discharge are preferable for seasonal use, reducing the risk of a dead light after extended periods of inactivity.
- Physical dimensions: Double-check length, width, and diameter to ensure a proper fit in the solar light’s compartment.
- Compatibility: Some products are not interchangeable with Ni-MH or Li-Ion cells. Verify that the chosen battery is intended for your device’s chemistry and voltage.
- Charger compatibility: Some packs exclude a charger. If you rely on a solar or external charger, confirm compatibility and availability of the appropriate charger.
- Environmental and safety considerations: LiFePO4 cells are typically favored for their stable chemistry and longer life. Ensure safe handling and disposal per local regulations.
- Availability and pack size: If you need multiple lights or replacements, consider multi-pack options to reduce stocking complexity and shipping frequency.
- Warranty and support: Look for brands that offer clear warranty terms and responsive customer support for essential peace of mind.
