One of the most common questions we get at AlerTrax is:

We’ve tested a wide range of AA batteries—from standard alkalines to advanced rechargeable lithiums—and we're here to break down the pros and cons to help you choose the best power source for your tracking device.

Types of AA Batteries Explained

• Alkaline Batteries: The everyday batteries you’ll find in most homes (Duracell, Energizer, Rayovac, etc.).

• Rechargeable Lithium Batteries: Available in USB-C or charger-based styles.

• Single-Use Lithium Batteries: Great for long deployments and tough environments.

Note: NiMH and NiCd batteries are not recommended due to voltage and memory issues.

Why Lithium Batteries Are Ideal for AlerTrax

• ❄️ Cold Weather Performance: Lithium works in sub-freezing temps where alkaline batteries often fail.
• 🔋 Longer Life: Higher energy density means fewer battery swaps.
• 🪶 Lightweight: Roughly 1/3 lighter than alkaline batteries—great for fleet shipping.
• 🌡️ Wide Temperature Range: Stable operation in both cold and hot conditions.

Note: NiMH and NiCd batteries are not recommended due to voltage and memory issues.

Rechargeable Lithium Battery Options

• USB-C Rechargeables: Easy to recharge with cables you already have, but sacrifice some battery capacity due to internal space used for connectors.
• Dedicated Charger Types: Slightly more effort to charge, but last longer and use more of the internal volume for actual battery material.

Potential Drawbacks

• Availability: Alkaline batteries are everywhere; lithiums are harder to find locally.
• Low Battery Notification: Rechargeables maintain output until they die—no warning drop like alkalines.
• Fire Risk: Rare, but lithium cells are more sensitive to extremes, especially during charging.
• Cost: Lithium AAs can be 3–6x the cost of alkaline, but worth it for critical, long-term uses.
• Charging Downtime: You'll need to swap and recharge, unless you keep spares ready.

Our Top Battery Recommendations

• Best Rechargeable: Mupoer Rechargeable AA Batteries
• Best Single-Use Lithium: Bonai Lithium AA Batteries
• Best Alkaline: Duracell Optimum AA Batteries

Conclusion

Lithium AA batteries are a smart upgrade for your AlerTrax devices—especially in cold weather or rugged outdoor conditions. While they cost more upfront, their longer lifespan, reliability, and cold tolerance make them the go-to choice for serious asset tracking applications.
