Best Battery Solutions for Asset Tracking Devices

May 06, 2026

Why Battery Selection Matters More Than Ever

Asset tracking devices are becoming smarter, smaller, and more connected, but none of that matters if the battery cannot support real-world performance. In modern tracking systems, battery selection directly affects uptime, reporting frequency, maintenance schedules, total cost of ownership, and even device size. For OEMs and product developers, the best battery solution is not simply the battery with the highest capacity. It is the power system that matches the device’s communication method, reporting behavior, operating environment, physical constraints, and expected service life. That is especially important in asset tracking, where products may be deployed across logistics, fleet operations, industrial sites, warehouses, and outdoor environments.

No Single Battery Fits Every Asset Tracker

Not all asset tracking devices have the same power profile. A BLE tag used for indoor tools has very different battery requirements than a GPS-enabled outdoor tracker or a cellular-connected asset monitor sending frequent location updates. Battery performance depends on a few critical variables:

how often the device transmits data,
how much power each transmission consumes,
whether GPS is used continuously or occasionally,
how large the battery can physically be,
and how often the device can realistically be serviced.

That is why the best battery solution for asset tracking devices depends on the use case, not just the specification sheet.

1. Primary Lithium Battery Packs for Long-Life, Low-Maintenance Deployments

For remote or difficult-to-access assets, primary lithium battery packs are often one of the best solutions. These batteries are especially effective when the asset tracker is expected to stay in the field for years without regular charging or service. Primary battery packs are ideal for devices that:

transmit at low to moderate intervals,
operate on low-power wide-area networks,
need long shelf life,
and are installed in places where battery replacement is infrequent but still more practical than recharging.

This type of battery solution is often a strong fit for container tracking, equipment monitoring, supply chain visibility, and low-touch industrial tracking applications. When the goal is ultra-long runtime with minimal maintenance, primary lithium packs are often the preferred choice.

2. Rechargeable Lithium-Ion Battery Packs for GPS and Cellular Asset Tracking

When an asset tracking device sends frequent updates, uses GPS often, or depends on higher-energy communication methods such as LTE-M or NB-IoT, rechargeable lithium-ion battery packs are usually the better option. These battery packs make sense when:

the device has a higher power draw,
regular location updates are required,
the asset is reused often,
or the product can be recharged during its operating cycle.

Rechargeable lithium-ion battery packs are well suited for fleet devices, mobile equipment, service assets, and high-value goods that need more frequent visibility. In these use cases, relying on a disposable battery may create unnecessary maintenance cost or require a physically larger battery pack than the design can support. A properly engineered rechargeable solution can help balance runtime, recharge cycles, device size, and performance reliability.

3. Compact Battery Solutions for BLE Tags and Indoor Asset Tracking

For indoor asset tracking applications, compact battery solutions are often the best fit. BLE-based trackers are typically used for tools, carts, medical devices, returnable transport items, and inventory inside controlled environments. These devices usually do not need the same wide-area communication capabilities as GPS or cellular trackers, so their power demands are lower. That makes smaller battery formats more practical. Compact battery solutions are best when the design priorities include:

small size,
low weight,
low power consumption,
and long runtime within a short-range environment.

If the tracker operates inside a warehouse, facility, or campus with nearby gateways or mobile devices, a compact low-power battery design can deliver efficient performance without increasing the size or weight of the product.

4. Custom Battery Packs for Rugged and Specialized Tracking Applications

Off-the-shelf batteries are not always enough for asset tracking devices used in demanding environments. Some products need to survive extreme temperatures, vibration, impact, moisture, or irregular transmission loads. Others must fit into highly specific enclosures or integrate with custom electronics. In these situations, custom battery packs are often the best solution. A custom battery pack can be designed around:

the required form factor,
peak and average current draw,
battery chemistry,
connector and wiring requirements,
charging behavior,
BMS integration,
PCB design,
testing and regulatory requirements.

For rugged outdoor GPS trackers, industrial monitoring systems, or specialized communications devices, custom battery design often delivers better long-term performance than trying to adapt a standard battery to a non-standard application.

5. Hybrid Power Strategies for High-Value Mobile Assets

In some tracking applications, the best solution is not simply a bigger battery. A better answer may be a more optimized power strategy. For high-value mobile assets, hybrid power planning can include:

rechargeable battery packs,
smart sleep and wake behavior,
efficient GPS scheduling,
lower-power communication logic,
and careful management of transmission frequency.

In other words, the battery solution should be designed as part of the whole system, not as an isolated component. A device that wakes too often, transmits unnecessarily, or runs GPS longer than needed will drain even a large battery faster than expected. For OEMs, improving battery life often comes from better electrical and firmware design as much as from choosing the right battery chemistry.

How to Choose the Right Battery for an Asset Tracking Device

Start With Reporting Frequency

The more often the tracker transmits, the more energy it consumes. A device that sends one update per day has a very different battery profile than one sending updates every few minutes. Understanding the required reporting interval is the first step in choosing the right battery solution.

Match the Battery to the Communication Technology

The network matters. BLE, LoRaWAN, LTE-M, and NB-IoT all have different power demands. Cellular-based tracking generally requires more energy than short-range or lower-power wireless technologies, so battery size and recharge strategy should be selected accordingly.

Design for the Real Operating Environment

Lab performance does not always match field performance. Outdoor trackers must deal with temperature swings, weather exposure, vibration, and physical stress. Indoor devices may have tighter size constraints but longer usable life. The battery should be selected based on where the device will actually operate, not just on nominal battery specs.

Think Beyond Battery Capacity

Battery capacity is important, but it is not the whole story. The best battery solution for asset tracking devices may also depend on:

safety requirements,
enclosure limitations,
charging method,
compliance needs,
product lifecycle expectations,
and the integration of BMS, PCB, and programming.

For many OEM products, custom battery design leads to better outcomes than choosing a generic battery pack.

What OEMs Should Prioritize in 2026

As asset tracking continues to expand across logistics, connected infrastructure, industrial equipment, and fleet visibility, battery strategy is becoming a major product differentiator. OEMs should prioritize:

longer field life,
lower maintenance needs,
reliable performance in real conditions,
compact mechanical design,
safe and tested battery systems,
and power solutions that scale with actual deployment needs.

The products that succeed will be the ones that match battery design to the real application instead of relying on a one-size-fits-all approach.

Final Thoughts

The best battery solutions for asset tracking devices depend on how the tracker communicates, how often it reports, where it operates, and how easy it is to service in the field. For low-maintenance, long-life deployments, primary lithium battery packs are often the best option. For GPS and cellular asset trackers that demand more frequent updates, rechargeable lithium-ion battery packs are usually the stronger choice. For indoor tags and compact devices, small-form-factor low-power battery solutions make the most sense. And for rugged or highly specialized applications, custom battery pack design is often the only way to achieve the right balance of performance, safety, reliability, and size. The right battery solution is not just about powering the device. It is about enabling the entire tracking system to perform reliably, efficiently, and cost-effectively over time.
