When you need to buy them, you need to know which type is perfect for your needs and you also need to compare their performance, power, safety and memory.

A lithium-ion (Li-ion) rechargeable battery allows you to charge it at any time you like. It doesn’t have a memory effect. And it can hold its charge for several months once you have charged it.
While NiCd rechargeable batteries have a memory effect. Their battery life will be shortened if it is not fully depleted and you recharge them. Therefore, you need to form a good habit of recharging your NiCd battery after the battery is used up. However, if you buy NiMH batteries, you don’t need to worry about the memory effect and you can charge it anytime. You can buy them easily in most local stores or simply buy them online.

When you plan to buy a rechargeable battery, one parameter you really need to know is the mAh (milliamp hour rating) which is used to measure the amount of energy that a battery can hold.

You also can consider buy a versatile charger, because some can recharge different sizes and types of batteries. Some even can recharge both lithium and NiMH batteries at the same time. The charger you plan to buy should be used through a USB port, a wall plug, and even a car charging port, which means the convenience.
