Rechargeable batteries vs alkaline - choose the best for you

Batteries play a significant role in 21st century. They become part of almost every electronic equipment. There are two kinds of batteries: rechargeable and non-rechargeable. In this era of technology, for portability and convenience, almost all electrical devices are designed to rely on rechargeable batteries to meet their power needs. From household applications to toys rechargeable batteries are used at the backend. Among them, the most common is the 18650 rechargeable battery. This article answers the most frequently asked questions about the rechargeable batteries vs alkaline.

1.What do rechargeable batteries mean?

Rechargeable batteries are essential for 21st century electronic appliances  as non-rechargeable battery cannot be used again after it is utilized.  Whereas, rechargeable batteries can be charged again after it is used. Rechargeable batteries have longer life span as compared to the normal non-rechargeable batteries.

2.All you need to know about rechargeable batteries

Rechargeable batteries are used in almost all applications. For instance, they are used in marine applications, golf carts,power tools, RVs, UPS solar system etc.

① Are rechargeable batteries alkaline or lithium? Which rechargeable battery type is best?

Alkaline batteries are non-rechargeable while lithium ion batteries are rechargeable.However, both batteries have different features. Both batteries have some advantages and disadvantages. The selection of them should depend on the type of electronic component you want to use.

② How long do rechargeable batteries last?

The answer to this question mainly depends on two factors：the types and usage of batteries.Different types of rechargeable batteries have different lengths of cycle life due to their different battery materials. Of all the common batteries on the market, lithium-ion batteries have the longest cycle life. Here is a table showing different life span of different batteries.

Of all the common batteries on the market, lithium-ion batteries have the longest cycle life. Here is a table showing different life span of different batteries.

If the batteries are properly used then the life span of batteries gets increased.On the contrary, if the batteries are improperly used the lifespan gets decreased and it gets weaken quickly.

③ How do I know if my rechargeable batteries are still good?

Rechargeable batteries last longer if used properly. If the rechargeable battery provides good backup and the lasting time after charging did not decrease significantly, then the battery is said to be good. Some batteries discharge rapidly when they become weak.

3.What is alkaline battery? How do I know if my battery is alkaline?

Alkaline battery is a kind of battery with alkaline as its primary source. When comparing alkaline vs. lithium batteries, the former has a lower energy density. When there is a comparison of rechargeable batteries vs alkaline, then the alkaline batteries have higher storing capability. Alkaline batteries are generally used in the form of cells in small electronic devices like chargers, calculators, watches and so on. It is a  common non-rechargeable battery on the market. You can also check if the cell shell is marked with an alkaline battery to know whether the battery is alkaline.

4.What is the difference between rechargeable batteries vs alkaline?

There are some differences between rechargeable batteries vs alkaline. Alkaline battery is used as a primary source while rechargeable batteries are secondary batteries. Alkaline battery has lower energy density and  storing capacity of charges compared with other types of batteries. The life of an alkaline battery is shorter than rechargeable batteries.

5.Can rechargeable batteries be used in place of alkaline?

This is the most frequently asked question and the answer is no. You can use a rechargeable battery like lithium battery as a replacement unless you make sure the voltage supply and the discharge current remain the same.

6.Frequently Asked Questions for alkaline batteries

① Can alkaline batteries be rechargeable? Why can alkaline batteries not be recharged?

No. Charging alkaline batteries is a very dangerous thing. If you don't master the conditions well, it is easy to cause safety problems (explosion, etc.), and its basic condition is small current charging. In fact, this charging method is very unreliable, because the current of most chargers is relatively large. 

② What happens if you recharge an alkaline battery?

If you recharge an alkaline battery, it is easy to leak the internal liquid of alkaline batteries, resulting in electrical corrosion and other safety hazards.

③ What are the pros and cons of alkaline batteries?

There are many advantages of alkaline batteries:

• The alkaline battery can last longer in the process of discharging;
• It is a replaceable battery and one can quickly replace it;
• Alkaline batteries are very cheap;
• The alkaline batteries are reliable as they can work after the long time even after one has not used them for a longer period of time;
• A relatively low temperature can help prolong alkaline battery life, but the temperature should not be too low.

There are many disadvantages of alkaline batteries:

• In the comparison of rechargeable batteries vs alkaline, the latter are not rechargeable, often we have to replace them with the new one;
• The use of circulating electrolytes increases the risk of leakage and easy to cause environmental pollution;
• Power output of alkaline batteries decrease with the time.

7.Is it better to buy rechargeable batteries or alkaline batteries?

Often rechargeable batteries vs alkaline is a hot topic. Rechargeable batteries are the better choice to buy as they provide us charging cycles more than 500 times. Rechargeable battery is one of the most  purchased around the world nowadays. As a kind of rechargeable battery, lithium battery has high energy density and long life span of up to 4000times. And it doesn’t suffer from the memory effect that can shorten the lifespan. If you want to buy the best lithium-ion batteries, please choose the most professional lithium batteries store, TYCORUN ENERGY will be your optimal choice.
