32140 Battery Specifications: Voltage, Capacity and Performance
32140 battery specifications vary depending on the cell chemistry, capacity, and design. The following sections explain the key electrical and performance parameters, using the UltraXel HL32140L 15Ah LiFePO4 cell as a reference.
Voltage and Capacity
A 32140 LiFePO4 battery typically has a nominal voltage of 3.2V. Its capacity depends on the specific cell model and is measured in ampere-hours (Ah).
Battery energy can be estimated using:
Energy (Wh) = Nominal Voltage (V) × Capacity (Ah)
For example, the HL32140L has a nominal voltage of 3.2V and a capacity of 15Ah, providing approximately 48Wh of nominal energy per cell.
Charging and Discharging Performance
With a high discharge capability, the HL32140L can support industrial equipment with relatively high power requirements, provided the operating conditions remain within its specified limits.
| Specification | UltraXel HL32140L |
| Nominal Capacity | 15Ah |
| Maximum Charge Current | 4.5A |
| Discharge Capability | 45A |
Cycle Life and Operating Temperature
Actual cycle life depends on operating temperature, depth of discharge, charging conditions, and other test parameters.
For conventional lithium-ion batteries, a commonly referenced operating temperature range is about −20°C to +60°C for discharging, while charging is typically more restricted, often starting at 0°C.
Specialized wide-temperature cells can operate beyond these conventional limits.
The HL32140-L is for wide-temperature applications, with an operating temperature range extending from −40°C to +85°C.
| Specification | UltraXel HL32140L |
| Cycle Life | ≥2,000 cycles |
| Operating Temperature | −40°C to +85°C |
| Capacity Retention | About 70% capacity retention after around 1,800 cycles at 45°C |
Common Applications of 32140 Batteries
The 32140 cylindrical format is used in battery systems where relatively high capacity per cell, long service life, and reliable power delivery are important.
Solar Street Lighting
Solar street lights require batteries that support daily charging and nighttime operation. High-capacity 32140 LiFePO4 cells can provide energy storage for outdoor lighting systems exposed to seasonal temperature changes.
Industrial Backup Power
Industrial control cabinets, automation equipment, and remote power systems require dependable backup energy. 32140 batteries offer high capacity and long service life for industrial installations.
Outdoor Telecom Backup Power
Telecom cabinets, communication nodes, and remote base stations need reliable power during outages. Wide-temperature 32140 cells can support backup systems operating in harsh outdoor environments.
Remote Monitoring and RTU Equipment
Remote terminal units (RTUs), telemetry devices, and outdoor data loggers often operate with limited maintenance access. Long-life 32140 batteries can support extended operation in remote locations.
AGV and AMR Systems
Automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) require stable power during movement and acceleration. High-discharge 32140 cells are suitable for industrial mobile equipment, including cold-storage applications.
Environmental Monitoring
Weather stations, hydrological sensors, and environmental monitoring systems require dependable outdoor power. Wide-temperature 32140 batteries can support long-term operation across changing seasonal conditions.
Different Chemistry Types of 32140 Battery
32140 cylindrical cells are available in different battery chemistries, including lithium iron phosphate (LiFePO4), sodium-ion, and lithium titanate (LTO). Although they share a similar physical format, their electrical characteristics and operating limits can differ.
| Feature | 32140 LiFePO4 | 32140 Sodium-Ion | 32140 LTO |
| Battery Chemistry | Lithium iron phosphate | Sodium-ion | Lithium titanate |
| Nominal Voltage | 3.2V | 3.0–3.1V | 2.3V |
| Reference Capacity | 15Ah | 10Ah | 9Ah |
| Nominal Energy | 48Wh | 30–31Wh | 20.7Wh |
| Cell Weight | Approx. 270–305g | Approx. 260–280g | Approx. 255–285g |
| Cycle Life | ≥2,500–3,500 cycles | ≥1,000–3,000 cycles | Approx. 10,000–20,000 cycles* |
| Charging Temperature | 0°C to +60°C (standard models) −40°C to +85°C (UltraXel HL32140L) | −10°C to +65°C | Approx. −30°C to +60°C* |
| Maximum Charge Voltage | 3.60–3.65V | 3.95–4.0V | Approx. 2.7–2.8V* |
(LTO cycle life, charging temperature, and maximum charge voltage are indicative values for LTO cell technology.)
A LiFePO4 battery is a practical option for applications requiring relatively high nominal energy per cell, established charging characteristics, and long service life.
Sodium-ion may be considered for applications prioritizing low-temperature performance and alternative battery materials.
LTO is particularly relevant to applications requiring frequent charge-discharge cycles, long cycle life, and low-temperature charging capability, although its lower nominal voltage and energy per cell must be considered.

FAQ
What is the difference between a 32140 and a 32700 battery?
The main difference is cell size. A 32140 battery is approximately 32 mm in diameter and 140 mm long, while a 32700 battery is approximately 32 mm in diameter and 70 mm long.
Are all 32140 batteries LiFePO4?
No. The 32140 designation refers to the approximate cylindrical cell dimensions, not the battery chemistry. 32140 cells can use LiFePO4 or sodium-ion chemistry, among other possible designs.
Can a 32140 battery be charged below 0°C?
Many standard LiFePO4 batteries do not permit charging below 0°C because of the risk of lithium plating and cell degradation.
Specialized low-temperature LiFePO4 cells, such as the UltraXel HL32140-L, may support charging below freezing within specified temperature and current limits.
How long does a 32140 battery last?
Some LiFePO4 32140 cells can last for thousands of charge-discharge cycles (like UltraXel HL32140L) under specified test conditions.
But cycle life should not be interpreted as a guaranteed number of service years. Actual lifespan depends on how the battery is used.
Can 32140 cells be used in custom battery packs?
Yes. Suitable 32140 cells can be connected in series and parallel configurations to achieve the required voltage and capacity.
A custom battery pack must also account for cell matching, current distribution, BMS protection, temperature monitoring, mechanical assembly, and charging compatibility.
