9V batteries are widely used in radios, clocks, smoke detectors, etc. Based on the materials used inside, these batteries can be divided into many types which have different capacities and different voltages. Furthermore, some of them are rechargeable, while others are not. In this article, we will focus on discussing the 9V Li-ion batteries, because they are rechargeable batteries with the highest capacity.

Although the 9V Li-ion batteries are called as “9V”, the voltage of these batteries is actually about 7.4V. It’s slightly lower compared with non-rechargeable batteries such as Alkaline, Zinc-carbon and Lithium. The capacity of a standard 9V Li-ion battery is about 620mAh. Basically you can use the 9V Li-ion batteries to replace Alkaline or Zinc-carbon batteries, although you will get slightly weaker but long lasting performance.

On the contrary, your “9V” li-ion rechargeable will definitely fail if your appliance needs exactly 9V. For applications that require more voltage and performance, you don’t need to replace your higher performance lithium batteries for 9V rechargeable ones. However, we still highly recommend 9V rechargeable Li-ion batteries because they can be reused hundred of times without steep degradation in performance. This means they are environmental friendly and also money-saving.

Additionally, Li-ion batteries have a relatively slower self-discharge than other batteries types, thus they have a longer shelf life. You can buy more Li-ion batteries as back up, because they can last for years, and won’t loss much capacity even after long periods of non-use. One thing you should be aware of is to not over-drain the voltage of your Li-ion batteries, otherwise they may not be able to be recharged.

While it is certainly easy to just grab any 9V rechargeable battery off of the shelf at your local convenient store, you should know that they are not all created the same. The biggest difference between them is performance, both in the duration of the 9V battery in any particular cycle and in the number of total lifetime full charge cycles. Additionally, some batteries have a longer shelf life, meaning they can be stored for longer without deterioration. The best thing to do to ensure quality and performance is to go with a name brand and one that has verified user reviews.

Furthermore, people may run into trouble as they use this battery in appliances which requires exactly 9V to work.

However, the EBLs have perfect performance when used in flashlights, radios, smoke detectors or any other devices which are not voltage dependent. The current is powerful, long lasting and stable. Better yet, the EBLs charge quickly, making them convenient to use.
