Bobbin-type lithium thionyl chloride batteries, for example, perform well in infrastructure, robotics, and industrial monitoring systems where long-term reliability is critical.
Part 2: Charge/Discharge Strategies
2.1 Cycle Management
You can extend the battery lifespan of remote monitoring devices by managing charge and discharge cycles with precision. Each full cycle—charging from 0% to 100% and then discharging back to 0%—counts toward the total cycle life of a lithium battery pack. Reducing the number of full cycles helps you get more operational years from your devices.
Best Practice | Description |
|---|---|
Manage Charging Cycles | Track and control each charge/discharge event to avoid unnecessary full cycles. |
Adopt Partial Cycles | Use partial charges and discharges to reduce wear and extend battery lifespan. |
Charge to 80% | Limit charging to about 80% to lower cell stress and slow down capacity loss. |
Avoid Deep Discharge | Keep battery levels above 25% to prevent damage and maintain long-term performance. |
Tip: You should schedule regular, partial charging sessions instead of waiting for batteries to fully discharge. This approach reduces stress on the cells and helps maintain consistent performance in industrial and security system deployments.
2.2 Depth of Discharge
Depth of discharge (DoD) measures how much energy you remove from a battery during each cycle. Lowering the DoD can dramatically increase the number of cycles a lithium battery pack can deliver. For example, if you only use 30% of the battery’s capacity before recharging, you can achieve over four times as many cycles compared to using the full capacity each time.
Depth of Discharge (DoD) | Number of Cycles |
|---|---|
100% | 4,000 |
30% | 16,000+ |
You should avoid deep discharges whenever possible. Keeping your devices within a moderate charge range—such as between 25% and 80%—reduces chemical wear and extends battery lifespan. This strategy is especially important for remote monitoring units in medical, robotics, and infrastructure applications, where reliability and long service intervals are critical.
Avoiding full discharges minimizes battery wear.
Keeping your device in the mid-range charge levels reduces the number of full cycle counts, which in turn extends the life of the battery.
Regular topping up is far better for lithium-ion batteries than letting them hit rock bottom.
Note: Micro-cycles, or frequent small charges and discharges, have a negligible or even positive effect on lithium-ion cell aging. Cells managed with micro-cycles can last nearly twice as long as those subjected to only deep cycles.
2.3 C-Rate Optimization
C-rate describes how quickly you charge or discharge a battery relative to its capacity. High C-rates can generate excessive heat, which damages the battery’s internal structure and shortens its lifespan. You should optimize the C-rate to balance performance and longevity.
High C-rates, especially above 1C, produce more heat and accelerate chemical wear.
Lower C-rates are more efficient and help prolong battery life.
Adjusting the C-rate to match your application’s needs ensures reliable operation and reduces maintenance costs.
Rate Type | Recommended | Maximum |
|---|---|---|
Charge Rate | 0.2C | 0.5C |
Discharge Rate | 0.5C | 1C |
You should select charge and discharge rates that fit your device’s requirements. For most remote monitoring devices, charging at 0.2C and discharging at 0.5C provides a good balance between efficiency and battery lifespan. This approach supports long-term reliability in industrial, security, and medical monitoring systems.
Callout: Proper C-rate optimization not only extends battery lifespan but also improves safety and reduces the risk of overheating in mission-critical environments.
