The SH14500 5th battery is one of the core products of Shenzhen Sunhe Energy co.,Ltd., widely used in consumer electronics, smart home devices, outdoor gear, and other application scenarios. As a high-performance 5th battery, the SH14500 has attracted widespread attention from customers. However, many customers have questions about the technical parameters, usage methods, and maintenance of the SH14500 battery. In this article, we will answer some of the most common technical questions about the SH14500 5th battery to help customers better understand and use the product.

Q1: What are the key technical parameters of the SH14500 5th battery?

A1: The key technical parameters of the SH14500 5th battery are as follows: nominal voltage is 3.7V, nominal capacity is 750mAh, nominal internal resistance is 60mΩ, discharge termination voltage is 2.75V, charging upper limit voltage is 4.2V, maximum charging current is 1C, maximum discharge current is 3C, working temperature range for charging is 0~45℃, and working temperature range for discharge is 0~60℃. The product size is 14mm in diameter and 50mm in length, which is consistent with the standard 5th battery size, making it compatible with most devices that use 5th batteries.

Q2: What is the cycle life of the SH14500 5th battery?

A2: The cycle life of the SH14500 5th battery is more than 1000 times. Cycle life refers to the number of times the battery can be charged and discharged before its capacity drops to 80% of the initial capacity. The SH14500 battery adopts advanced lithium-ion technology and high-quality materials, which significantly improves its cycle life. Under normal use conditions, the battery can be used for 2-3 years, depending on the frequency of use and the operating environment.

Q3: Can the SH14500 5th battery be charged with charger?

A3: The SH14500 5th battery is a lithium-ion battery, which requires a dedicated lithium-ion battery charger. It is not recommended to use a普通 charger (such as a nickel-cadmium or nickel-metal hydride battery charger) to charge the SH14500 battery, as this may cause overcharging, overheating, or even damage to the battery. When charging the SH14500 battery, please use a charger that is compatible with 3.7V lithium-ion batteries, and follow the charger’s instructions to ensure safe charging. The charging time is usually 2-3 hours, depending on the charger’s current and the battery’s remaining power.

Q4: What should I do if the SH14500 5th battery is over-discharged?

A4: Over-discharging refers to the situation where the battery’s voltage drops below the discharge termination voltage (2.75V). Over-discharging can cause damage to the battery, reducing its capacity and cycle life, and may even make the battery unable to be charged. If the SH14500 battery is over-discharged, you can try to charge it with a dedicated lithium-ion battery charger. If the battery cannot be charged normally, it may have been permanently damaged, and it is recommended to replace it with a new one. To avoid over-discharging, please do not use the battery until it is completely dead, and charge it in a timely manner when the device prompts low power.

Q5: How to store the SH14500 5th battery correctly?

A5: Correct storage is crucial for extending the service life of the SH14500 5th battery. When storing the battery, please keep it in a cool, dry, and well-ventilated place, away from direct sunlight, high temperatures, and humidity. The ideal storage temperature is 10~25℃. Before storage, please charge the battery to 50%-70% of its capacity, as this can prevent over-discharging during storage. Do not store the battery in a fully charged or fully discharged state for a long time. In addition, please keep the battery away from metal objects to avoid short circuits.

Q6: Is the SH14500 5th battery safe to use?

A6: The SH14500 5th battery is designed with multiple safety protection measures, including over-charging protection, over-discharging protection, over-current protection, and short-circuit protection, to ensure safe use. The battery’s shell is made of high-quality, fire-resistant materials that can withstand high temperatures and impact. In addition, the battery is free of harmful metals such as cadmium and nickel, complying with international safety standards. However, it is still important to use the battery correctly, such as not disassembling, puncturing, or burning the battery, to avoid safety accidents.
