Best Rechargeable 9V Batteries with Charger 2020 Detailed Review

Best Rechargeable 9V Batteries with Charger 2020 Detailed Review.

Best Rechargeable 9V Batteries with Charger: In the electronic modern world, 9 V batteries are everywhere. In fact, these are some of the most common batteries in the entire world, especially since they were originally introduced for the earliest transistor radios. 


Even if you don’t know the voltage, you can probably tell a 9 V battery apart from the others due to its iconic shape: all of them look like a rectangular prism and have a polarized snap connector at the top.

Because of their early design and versatility, 9 V batteries are typically used in electronics that require consistent power, like smoke detectors or clocks. 

EBL 9v 5-Pack Batteries with Charger

EBL 9v 5-Pack Batteries with Charger 

This package comes with five 9 V batteries, and a charging station specifically designed to support this number, although you don’t need to have all five plugged in to get some charging done.

The manufacturer, EBL, has been designing batteries and their charters for more than 20 years and has perfected their techniques.

As a result, these batteries are an excellent choice for smoke detectors, toys, clocks, and even medical devices due to their reliability and consistency. 

These batteries are nickel-metal hydride or NiMH. These aren’t quite as energy-dense as lithium-ion batteries, but they have a great capacity compared to cheaper batteries you can buy at most stores. 

Charger Form and Function 

The included charger with this kit is another high-quality piece of equipment. As we stated, it has special slots for all five of the included batteries, as well as a storage case in which you can keep the charger and any extra batteries you’re not currently using for organization purposes. 

LP 9V Rechargeable Battery Pack with Micro USB Charging Port

This battery/charger combo is another excellent pick, and it’s a little more affordable than the EBL charger. It comes with a two-pack of 9 V rechargeable lithium-ion batteries.

Lithium-ion batteries are an excellent choice for most rechargeable power needs and are most often used for portable electronics.

They, along with the two-pack contained in this kit, provide high-density energy and excellent power efficiency. They usually have a low self-discharge rate of about 2% per month. 

The LP 9 V lithium-ion batteries are ideal for lots of portable electronics like walkie-talkies, microphones, toys, flashlights, musical instruments, and medical devices.

They have an excellent low self-discharge rate that guarantees that they’ll still have 75% of their capacity after three years, just like the EBL batteries.

Because they last a long, they’re a great choice if you want to reduce your carbon footprint and be environmentally conscious. 

Charger Form and Function 

These batteries circumvent the need for a dedicated charging port, instead of relying on a micro USB cable that plugs right into the batteries themselves and into a wall outlet.

Because of the micro USB cable, you can also charge these individual batteries anywhere you can fit the USB end; devices like laptops or tablets work just as well, as do car chargers that have USB functionality. 

Tenergy 9V Rechargeable Battery with 2 Bay 9V Charger

The Tenergy batteries are nickel-metal hydride as well. This kit comes with 49 V batteries, each of which is ideal for a variety of uses like smoke alarms, walkie-talkies, and any hydrant medical device.

The dimensions are about 48 mm x 26 mm x 16 mm. They’ll recharge up to 1000 times, in part because of their very high capacity. This limits the damage caused by overcharging or letting them sit for too long. 

These batteries can be charged from several charger models from the same manufacturer, which has been producing batteries and electronic gear for many years.

Charger Form and Function 

The charger of this kit is the main attraction. It’s incredibly compact and plugs right into any typical wall outlet rated for 100 V to 240 V AC.

It’s perfect for use throughout the entire world without needing a converter, although you might need a plug adapter based on outlet shape.

This high-performance charger can even be folded so you can store it in a variety of places or allow it to charge your batteries in peace while being discreet, even if you place it in a main living area.

Overall, each of these 9 V battery packs with their chargers is a great choice. However, we have to say that the LP 9V Rechargeable Battery Pack with Micro USB Charging Port will probably be the best choice for most for a few reasons.

For starters, the batteries themselves are lithium-ion, while the other two choices are nickel-metal hydride. This means that the batteries last a little longer than their competitors and their capacity will diminish at a slightly slower rate. 

The charger cable can be taken just about anywhere, and it works so long as you have a USB port with which you can draw power. It certainly takes up way less space than the EBL charger. 

However, both of the other options are great if you want to charge multiple batteries at the same time. The LP pack only lets you charge a single battery at once, which can be inconvenient if you need multiple to power a device. So go with the first or third options if you want the ability to charge multiple 9 V batteries simultaneously.
