PKCELL Rechargeable AA Batteries Review

Do Batteries Expire?

Today’s article will cover the PKCELL battery review whose noteworthy product is PKCELL which is a battery manufacturing firm with headquarters in Shenzhen, China. They produce several different types of batteries. However, one of the most important items offered by the organization is the PKCELL Rechargeable AA Batteries. 

Rechargeable AA batteries nearly always have a longer lifespan and lower cost, producing less waste than their disposable counterparts. This is true regardless of whether you use them in a wireless mouse, a toy, or a torch.

Most of today’s consumer devices, like your smartphone, are equipped with an internal battery that can be charged via a USB wall charger or a portable power bank. 

However, many other gadgets, such as alarm clocks, cordless power tools, digital scales, flameless candles, flashlights, gaming controllers, wireless keyboards, and many more, continue to use AA or AAA batteries. 

In some situations, this makes them bigger than they would be if they had batteries built in. Still, it also enables you to change the batteries in the device long before you need to replace the item itself, which may significantly increase the gadget’s lifespan. 

If you already have one of these types of devices, it is pretty likely that you will find it beneficial to get some rechargeable batteries. Throughout this article, PKCELL Rechargeable AA Batteries will be reviewed with their various features.

What Can You Do to Make Your Batteries Last Longer?

Keep batteries in a cool, dry area while not in use. Since heat accelerates the chemical reactions within most batteries, keeping them in a hot area will cause them to degrade faster than if they were stored in a cooler environment. 

Similarly, humidity results in condensation, which may lead to corrosion and leaks (this is another reason you shouldn’t keep batteries in a refrigerator or freezer, despite the widespread belief that this is an acceptable practice).

Charge the batteries at a pace that maximizes their effectiveness. Choosing the most appropriate charging rate for your batteries may assist in optimizing the amount of time they will last. When the batteries have reached their maximum capacity, turn off the power. When a high-quality charger determines that a battery has been charged to capacity, the charging process will cease. 

Despite this, you should never keep rechargeable batteries connected to their charger after they have reached their maximum capacity, just in case this function becomes inoperable (which can happen if the charger misses the signal from the battery). In addition, because batteries deteriorate more quickly when overcharged, you will need to purchase new ones more quickly.

Never combine fresh and used batteries in the same device. Even if the remaining power in the other batteries is sufficient, most AA- and AAA-powered electronic devices will become inoperable after the battery with the lowest capacity expires. 

It is recommended that you use the batteries in groups according to the date that you purchased them. When powering a single gadget, don’t combine batteries from various packs of the same brand or other packs of the same brand altogether for the same reason.

Features of PKCELL Rechargeable AA Batteries

High Voltage and High Energy  

PKCELL rechargeable battery is notable for several reasons, which is why it’s the main guest on our PKCELL battery review, one of which is its high voltage and energy levels. The fact that the product has a high voltage and energy provides it with various benefits. Standard batteries with the same capacity as high-voltage batteries are heavier, but high-voltage batteries have a higher discharge platform. Thus, high-voltage batteries are lighter. 

The increased voltage has, on average, a marginally positive effect on the efficiency of various equipment. Batteries with a high voltage also often have a high energy density. They can produce more power while maintaining a long battery life because they can give a greater capacity under the same operating circumstances. 

Ni-Zn batteries have a rated operating voltage of 1.65 volts, which is about 0.4 volts greater than the voltage of Ni-Cd and Ni-MH batteries. As a result, ni-Zn batteries may have an energy output of up to 60–80 Wh, much greater than the 40–60 Wh output of Ni-MH batteries and the 20–40 Wh output of Ni-Cd batteries. Compared to lead-acid batteries, its capacity to provide energy while maintaining the same quality is three times more.

High Discharge Power  

Despite being on the market for decades, rechargeable batteries remain popular. Considering the advantages they provide, it’s not hard to understand why. For one, throwaway batteries are bad for the environment and should be replaced with rechargeable ones. In addition to their durability, they produce less waste when used often. This is especially true for gadgets that need a lot of power and drain batteries quickly.

You may save money and time using rechargeable batteries compared to disposable ones, and they consume fewer resources. Rechargeable batteries allow you to place them on a charger until they are fully charged (or at least functioning) again. 

Therefore, the batteries’ discharge power is crucial in this application. In most cases, batteries with a rapid discharge rate can quickly recharge. Lithium ions in high-discharge rate batteries are housed in the negative graphite electrode during charging and the positive electrode during discharge.

The discharge power is an area where the PKCELL rechargeable battery shines, not only here but across the whole PKCELL battery review. This is due to the Ni-Zn battery’s favorable performance under high-current discharge conditions. Its high voltage allows it to offer discharge powers of 10c and 20c, far greater than those of Ni-Cd and Ni-MH batteries. Moreover, in the same discharge capacity settings, it can provide power for a more extended period.

Typically, the initial cost of rechargeable batteries is higher. Understandably, rechargeable batteries would cost more than their disposable counterparts, given that they may be used again after being purchased. One of the reasons some people prefer to use disposable batteries is that they need less out-of-pocket investment to get started. 

However, rechargeable batteries save you money in the long term since they may be used hundreds of times before needing to be replaced. Therefore, rechargeable batteries make economic sense in this application.

To be cost-effective, a product must be able to fulfill all of the customer’s needs at a price comparable to or lower than the prices offered by other suppliers. The PKCELL Rechargeable AA Batteries are also cost-effective products. Ni-Zn batteries have a lower overall cost than Ni-Cd and Ni-MH batteries because of their higher voltage, which allows them to employ fewer particles in the battery pack. 

A battery pack consisting of 3 Ni-Zn batteries may be purchased for 10% less if a 4.8V Ni-Cd battery pack is utilized. This product has a 500-cycle life. If you are looking for a battery that will not make you regret it economically in the short and long term, PKCELL rechargeable battery may be your product.

High Substitutability 

The intended use is the primary factor in deciding between disposable and rechargeable batteries. It is recommended to use rechargeable batteries for anything that has a high power consumption rate but is used for a short period. 

High-consumption gadgets, like the remote control for your kid’s toy vehicle, which consumes AA or AAA batteries, reap the economic and environmental advantages of rechargeables much more quickly. Unfortunately, wireless computer mice are just as great a drain on batteries as some of the toys kids play with.

On the other hand, goods that have a low energy demand over a long period and are changed rarely, such as smoke detectors or your TV’s remote control, benefit more from using single-use disposable batteries. In the same vein, it’s best to use single-use batteries in items like flashlights that you store in case of an emergency. 

High substitutability is a critical factor for the batteries in this setting. Ni-Zn storage batteries may be used to power electric tools, and they are a great alternative to Ni-cd and Zi-MH batteries. In addition, ni-Zn batteries are an energy-efficient alternative to conventional alkaline primary batteries. With this feature, you could be willing to use PKCELL rechargeable battery.


This is where we part in our PKCELL battery review. When shopping for rechargeable batteries, it is essential to make sure that you do so exclusively from reliable retailers. Failing to do so might result in faulty batteries. A bet is taken when a consumer purchases a battery from a supplier of inferior quality. 

In addition to the possibility that the battery is a fake, there is also the possibility that it was carelessly kept, has gone bad, or was even damaged. Unfortunately, the efficiency and security of the battery are both susceptible to being impacted by all of these factors.

Because many rechargeable batteries are constructed out of lithium, poor storage that results in exposure to heat or moisture may cause the battery to behave incorrectly, potentially resulting in physical harm or damage to your device. However, when all of your requirements are considered, you may find that the PKCELL Rechargeable AA Batteries are one of the successful and risk-free goods that can fulfill all of your needs.

Review: If you own an HP Reverb G2, these batteries are the exact voltage required for them.

Mike B – ⭐⭐⭐⭐⭐

Review: I use these PKCELLS in a travel shaver that takes 2 AA size removeable batteries. Nickel-Zinc batteries are the only type that power the shaver up to an acceptable speed. Using the proper charger, which I purchased before, these batteries charge up to about 1.7 volts. Alkaline batteries are 1.5 volts. Nickle Cadmium and Nickle Metal Hydride batteries charge up to only about 1.2 volts. The extra .2 to .5 volts you get from each Nickle Zinc battery really makes a difference. I’ve been using the PK Cell batteries for about 6 weeks and so far I’m very pleased with them. When the batteries are new, they can power my travel shaver every day, for about a month, on a single charge! But the charge gradually diminishes. Although they may charge up to full voltage, they will need to be charged more frequently. In 6 months to a year, they may need to be replaced, so I don’t think their lifespan is as long as other types of rechargeable batteries. For the extra voltage, I’m willing to put up with a lesser lifespan. These would also probably work great in flashlights, for a little extra brightness. Incidentally, the technology behind this type of battery isn’t new. It was invented by Thomas Edison, 100 years ago.

lental – ⭐⭐⭐⭐⭐

Review: I bought eight of these for one of two trail cameras that are battery eaters. I had tried a set of rechargeable alkaline batteries but they only charged to their full 1.5-volt capacity twice before they stopped taking a full change. So far, I’ve been impressed with these NiZn batteries because they last longer and cost less than 1.5 volt alkaline, lithium NiMh batteries. We’ll have to wait to see how long they last.

David Blackman – ⭐⭐⭐⭐

Review: These are just very very slightly larger in diameter than regular AA batteries. The battery case where I used them was a little fussy. I think they will work for 95% of applications.

TimmyP – ⭐⭐⭐

Review: These are probably the BEST rechargeable Ive ever used. They last a ridiculous amount of time in devices that eat batteries because they suck power.

Will Boyer – ⭐⭐⭐⭐

Review: I use rechargable batteries for my VR controllers and normal rechargeables die after maybe 8 hours of use. It was recommended in a VR accessories video to use NiZn batteries instead. These perform great and last at least twice as long. I did have a problem with one battery where it completely drains and is unusable so I had to buy another 4 pack. I now use one in my wireless mouse as well.

Chris Lipps – ⭐⭐⭐⭐

Review: The bad: Out of two packs I have one or two batteries that have not done well with use. They now do not charge and do not work. This could either be a material issue or a quality control.

Thad V. – ⭐⭐

Review: I purchased my first set of these with the charger, and another 4-pack separately. They work great for about the first year. Then they rapidly stop holding a charge. I use these in our door locks because the extra power gives the lock the added boost it needs to extend when the door isn’t exactly lined up. Our door locks get regular usage – about 5 to 10 uses per day. I initially had a schedule to remove and charge every two months. After a year, I would need to charge every month. Recently I noticed that even with a fresh charge it sounded like the lock was struggling. I put them on the battery tester and only 1 of 8 still has 1.6V. The rest are between 1.2 and 0.3V right off the charger. I’d love to love these, but 2 years, and about 18 charge cycles is not worth it.
