The new type 1.5V rechargeable Li-ion batteries are available in recent years. Compared to AA/AAA rechargeable NiMH battery and disposable alkaline battery, some people may not so familiar with this new Li-ion battery. So how about its performance? More info here. Li-ion batteries normally operate 3.7V per cell. Through a built-in circuitry, the battery is stepped down to a 1.5V constant voltage output. There are some outstanding advantages of this Li-ion battery. *1.5V constant output, stable performance Because of the high density of Li-ion battery, the energy of 1.5V rechargeable Li-ion battery is higher than that of NiMH and disposable alkaline batteries. And the output of the 1.5V rechargeable Li-ion battery keeps a constant voltage of 1.5V, more stable and powerful. The devices such as racing cars, remote controls, electric toys, etc. that use this battery can maintain more stable performance. *Longer battery lifetime For rechargeable NiMH battery, due to the memory effect, it may need to charge and discharge the battery from time to time to release the capacity. This will inevitably shorten the battery life. Compared with NiMH batteries, lithium batteries have no memory effect. You can charge and discharge the 1.5V rechargeable Li-ion battery at any time. And good maintenance also helps to extend the battery lifespan. *Having all advantages of Li-ion batteries Since the 1.5V rechargeable Li-ion battery is reduced voltage from the 3.7V Li-ion battery, it has all the advantages of Li-ion batteries, such as fast charging speed, low self-discharge rate, high safety and performance, large discharge current, excellent high and low temperature discharge performance. *Eco-friendly Rechargeable Li-ion batteries almost always last longer, reduce waste compared with disposable batteries, truly economical and environmentally friendly...
