3.7V Li-Ion Rechargeable Batteries

Li-Ion 3.7 V Rechargeable Batteries

Rechargeable batteries are a cost efficient and environmentally-friendly solution for powering different devices, such as digital cameras, remote controls and flashlights. The upfront cost might be slightly higher than that of single-use batteries, but you do use them more than once, so eventually they pay off. Note that rechargeable batteries use less non-renewable natural resources than disposable ones and thus have a smaller impact on the environment. Li-ion batteries are one subtype of rechargeable batteries and there are several important features to take into account when buying and using them.

Sometimes, you can confuse the lithium-ion batteries with ordinary lithium batteries. There is a difference because most lithium batteries are in fact non-rechargeable and you can only recharge the Li-ion batteries. The latter use lithium compounds rather than pure lithium, which is less stable and thus not suitable for recharging.

Compared to other rechargeable batteries, the Li-ion batteries have a higher energy density and can thus store more energy for their weight and size than other types. Some Li-ion batteries, such as 3.7 V 5 Ah rechargeable batteries, operate at higher voltages than NiCd or NiMH batteries, you can even use only a single cell instead of multiple ones. Another major advantage is that Li-ion batteries hold their charge better than other kinds of rechargeables and are full even after months in storage.

Rechargeable Lithium-ion batteries require a special charger due to their higher voltage. Putting them into another kind of charger could set it on fire, so they are not available in standard sizes to avoid such a situation. All Li-ion batteries differ in terms of shape and size, so you would need a separate charger for each type.

Li-ion batteries use different kind of naming convention to avoid confusion with standard batteries, as using a Li-ion battery in a device that requires a standard battery would damage the device. Instead of letters, the Li-ion batteries have numbers. Therefore, the AAA batteries would actually be 10440, while the AA lithium-ion rechargeable batteries would be 14500. C and D standards are 25500 and 32600, respectively.
