For many years, we have been using a lot of rechargeable batteries. Battery packs have gone a long way beginning from its nickel-cadmium roots. This is considered to be the first alkaline battery. This was used heavily for commercial purposes before being replaced by the more advanced nickel metal-hydride rechargeable battery. This was more reliable and lasts longer compared to nickel-cadmium batteries. However, the nickel metal-hydride battery was soon replaced by an even more advanced battery. The lithium-ion rechargeable battery stores even more power and so, lasts longer in-between charges. With more power, it can also juice up more power-hungry devices, but do you know the 18650 Battery Dimensions & Specifications?
A standardized format used in producing li-ion rechargeable batteries is the 18650 format. This is a cylindrical cell measuring 18 X 65mm. The 18650 format battery is the most economical li-ion rechargeable battery format based on cost-to-energy ratio.
Advantages of Li-Ion Rechargeable Batteries
Li-ion batteries are usually chosen for various purposes. These are as follows:
- It is able to store more power.
- It can provide power to power-hungry devices.
- Relatively low maintenance.
- Built in features for longer lifespan.
The best rated li-ion 18650 batteries can store a lot of power with only a relatively short charge. This allows you to use your appliance for a much longer period. For instance, with just about 2 hours of charge, the best rated li-ion 18650 battery can run for about 8 hours.
The 18650 li-ion battery can provide a stronger power during usage. This means that it can cater to appliances that require more power such as electrical drills. If the battery provides less power, the drill may not operate in its optimum condition since it is not drilling as hard as it should. With a stronger power, the drill is able to turn faster and thus, drill harder.
With best rated li-ion 18650 batteries, you do not need to take care in charging as you do with other types of batteries. This is because it is relatively difficult to overcharge the battery. When it has reached its full capacity, its integrated circuit will stop it from being charged further. On top of that, you do not need to discharge the battery periodically even if you do not use it since there is no memory effect.
As mentioned above, the 18650 li-ion battery contains extra features that help it to have an easier maintenance. This includes the ability to regulate voltage levels when discharging. Other than that, some products also have thermal cut off protection, effectively terminating access to the battery if it overheats. All this adds to a longer lifespan of the best rated li-ion 18650 batteries.
When buying 18650 rechargeable batteries, there are a few points that should be considered. These are:
- storage and output levels.
- chargers.
It is very important to take note of a li-ion rechargeable battery’s storage levels. Usually, it is available in the following flavors:
- 1600mAh
- 2400mAh
- 2600mAh
- 3000mAh
- 3600mAh
The higher the number, the more storage the battery is capable of. It should also be noted that with a higher storage capability, it will take a longer time for it to be fully charged. In relation to that, the output levels of the battery should also be noted. The normal output level for 18650 li-ion batteries is about 3.7V. A higher number means more power is output to the appliance.
Along with rechargeable batteries, we should also consider the chargers for these batteries. There are many different types of chargers. Some of them can charge only 2 batteries at a time while others can charge up to 4. Some chargers have light indicators while others do not. We should choose one that fits our requirements and budget.
