Key Performance Metrics of 7.4V Lithium Ion Battery

The key features of 7.4V lithium-ion batteries are highlighted below:

In terms of voltage, 7.4V can be compatible with various devices such as small electric screwdrivers, providing stable and moderate power output. It has a relatively high energy density, which enables it to store sufficient electrical energy in a limited volume, thereby extending the operating time of the device. With a low self-discharge rate, the battery loses its charge slowly when not in use, which is beneficial for long-term standby. It also has a long cycle life and can withstand multiple charge-discharge cycles, reducing the cost of battery replacement during the equipment's service cycle and providing reliable and continuous power support for small electric tools, some remote-controlled models, etc. It performs excellently in various application scenarios of medium and low power equipment.

What are the typical lifespan and cycle life of 7.4V Lithium Ion Batteries

The cycle life of 7.4V lithium-ion batteries generally ranges from 800 to 1000 times. However, this figure may fluctuate due to the influence of usage conditions. For example, under conditions such as within a suitable temperature range, avoiding deep charge-discharge, using a compatible charger and having a good battery management system, the cycle life of the battery can be extended. Conversely, if it is used under harsh conditions such as high temperatures, high-rate charge-discharge, and deep charge-discharge, the cycle life will be significantly shortened.
