How to Choose The Best 18650 Chargers
Not all chargers are created equal. Each of them has its own features that might be different from the others. To choose the right charger, here are a number of factors you have to consider:
Lithium Ion Battery (18650 and Others) Charger and Charging Options
There are two different types of lithium batteries. Lithium batteries which are not rechargeable and lithium ion batteries which are rechargeable. Lithium batteries are made from pure lithium metal whilst the ion batteries are made from lithium compounds which are much more stable than the metal.
Lithium ion batteries are more expensive but can be recharged many times. Most of them can be recharged at least 500 times and some recently produced batteries are rated to accept 1000 recharges.
Lithium ion batteries are lighter and smaller than other rechargeable batteries and operate at a higher voltage. They operate at 3.7 volts compared to 1.2 volts for other rechargeable.
This means that only one battery is required in some cases rather than several of the lower voltage batteries. They also retain their charge for a longer period and will remain almost fully charged for many months.
Lithium ion batteries are much more expensive than other rechargeable due to their complexity and small manufacturing volume. In time it is probable that this price will drop considerably as the batteries become more popular and are made in bigger numbers.
They are not made in standard AA, C and D sizes since they must not be recharged using these standard battery chargers which do not operate at the correct voltage and could damage the lithium batteries or fail to charge them at all.
Lithium ion batteries are made in many different shapes and sizes to suit the particular device they are used in. Each of these devices takes batteries of different shapes,sizes and capacities. Some purposes may require big high capacity batteries whilst others use much smaller sizes. Each of these will require its own charger design.
Lithium ion batteries can be manufactured to produce from 1.5 volts to over 4 volts and higher current output than their alkaline counterparts. This gives them two to three times the power output of zinc/carbon or alkaline batteries.
This high output and long life makes them a favorite for many people. They are in fact much better than any other batteries produced to date from most points of view. It is expected that this technology will be further developed in the near future and as production levels increase prices will fall to be more competitive with alkaline batteries.
Standard lithium batteries come in the usual AA, AAA, C and D sizes, 18650 and can be used in devices which require these standard size batteries. They are manufactured most of the large battery companies.
They have long life in use and long shelf life in storage and are excellent batteries. They are recommended for use in any device which normally uses alkaline batteries.They have in most respects taken over a large part of the market which formerly used alkaline batteries.They cost a bit more but have huge advantages in capacity and length of life.
An electronic device powered by a lithium battery will operate for much longer than it used to with an alkaline battery. Standard lithium batteries are not rechargeable and must be replaced when worn out. Since they are fairly costly it is obvious that anyone who uses a lot of these batteries would be much better off to use rechargeable batteries which are suited to the device in question.
NiMh Battery (18650 and Others) Charger and Charging Guide
NiMh batteries can be charged with either an MiNh charger or a Nicad charger. It will take longer with a Nicad charger because NiMh batteries have a higher capacity than Nicad. NiMh battery chargers can be purchased in smart charge or timer controlled models.
The timer controlled charger will charge for a set period of time then shut down at the end of that time.. A smart charger charges till there is a full charge in the batteries then shuts down automatically.
Why doesn't everyone use a smart charger then?. Simply because they are more complex and cost considerably more. So some users will settle for a fixed time charger in order to save some money.
They are saving some on the purchase price but can have problems with partial recharging when the timer shuts off before a full charge has been accomplished. For this reason most people will find that a smart charger is the best buy even at a higher price.
If you are using lower capacity batteries then a fixed time charger will do the job very well. If you use high capacity batteries it is much wiser to get a smart charger. The fixed time charger will shut down before the high capacity batteries are fully charged. The smart charger will keep on charging till the cells are completely charged. Obviously the smart charger will save time and annoyance.
Solar powered battery chargers are also available.These have a very low charging rate and are best suited to charging lower capacity batteries such as Nicads. You can charge NiMh batteries with a solar charger but it takes a long time to get a full charge.
These chargers can be useful if you are camping in the outdoors, away from a power supply. Otherwise a smart charger will be your best choice.
Low self discharge NiMH batteries are made by several companies. These batteries can retain 70% to 85% of their capacity when stored at room temperature for one year, whilst standard NiMH batteries can lose up to 50% of their charge in the same time.
Apart from their longer shelf life and higher cost LSD NiMH batteries are similar to ordinary NiMH batteries and can be charged with the same chargers. LSD NiMH batteries can be recharged up to 1000 times whereas normal NiMH batteries can only be charged up to 500 times.
Look for LSD batteries which have their specifications printed on the battery casing to ensure that you are actually getting LSD batteries. There have been problems with some manufacturers repackaging standard batteries as LSD which they are not.
Always read specifications of any rechargeable batteries to be sure that you are getting the type of battery you are in the market for.
Sanyo have recently introduced a new version of their Eneloop LSD NiMH battery which retains 75% of its charge after three years and can be recharged up to 1500 times. It is likely that there will be many more improvements to rechargeable batteries as time goes by.
For those who use their battery powered devices a lot, rechargeable batteries although more expensive to purchase initially will provide a great saving over the cost of replacing standard batteries many times.
With the number of the chargers on the market to choose from, it’s very easy to get overwhelmed. However, I’ve simplified the entire process for you. With the help of my best 18650 battery charger reviews, choosing the charger that can fit your needs becomes a lot quicker and easier.
With this list, you’ll no longer have to worry about slow battery charging times, overcharging, and more. If you’ve got questions, don’t forget to leave us a comment below. Thanks for reading!
