Here are some key points to consider:

There are three main types of rechargeable batteries: Nickel-Metal Hydride, Lithium-ion, and Nickel Cadmium. Depending on your purpose and preference, a particular type can come in more beneficial. Learn more about them below
Mainly used for batteries for laptops and mobile phones a decade ago, Nickel-Metal Hydride is now also found on single-use or rechargeable batteries. Even though it is more expensive than NiCd and lead-acid batteries, it is also longer lasting. You can partially charge or discharge NiMH batteries as often as you like, but they will always retain their full capacity.
NiMH batteries are very common and easy to purchase in any hardware store or supermarket because they are cheaper to manufacture. Also, they are the most sustainable type for many household appliances. With their high energy capacity, these batteries are recommended for high-drain devices like digital cameras or flash units.
Lithium-ion batteries have the largest power density and longest shelf life among rechargeables. Primarily used in electronics, they are also rarely found in a standard AA or AAA size since they offer much higher voltage than most consumer devices and need a special charger.
If you plan on purchasing one, ensure that the indicated voltage is at 1.2 or 1.5 volts to prevent over-voltage to your devices. This type of rechargeable battery is best used for computers, smartphones, GPS sports watches, portable power devices, or some bike lights.
Nickel Cadmium batteries were once the leading type of rechargeable battery until they were superseded by NiMH or Li-ion batteries. One reason is that cadmium is highly toxic and could pose an environmental hazard when not disposed of properly. Despite this, it remains a choice for specific devices, including two-way radios, emergency medical equipment, and other power tools.
You can get this battery's full potential when it is completely discharged or drained after every use before recharging it. Its charging cycle can reach nearly a thousand times or about three years before it expires. Overall, NiCD batteries are reliable for certain devices, but only if the user is willing to overlook their harmful consequences to the environment.
Typically, rechargeable battery size comes in AA or AAA, which holds much higher capacity and lasts longer than disposables. A rechargeable battery's capacity is expressed in milliamp-hour or mAh, a unit that measures power over time. It describes the energy charge a battery can store and how long it will take to expend the stored energy.
For instance, a 3000 mAh rechargeable battery could power a device that draws 100 milli-amp (mA) for 30 hours, while for a device that draws power at 200 milli-amp (mA), the battery will only last for 15 hours. In simpler terms, the higher number on the capacity or mAh, the larger power it can store, and the longer it can power up a device at a given usage.
Commonly used battery sizes are AA, AAA, AAAA, C, D, and 9V batteries. AA or "double A" batteries are the standard size for most devices. Triple A batteries, on the hand, generate less power and are typically used on remote controls and calculators. Quadruple A are the thinnest ones and are usually for small devices.
Meanwhile, C batteries are for heavy-duty devices such as flashlights, radios, toys, and instruments. In comparison, D batteries are for those that require longer playtime. And finally, 9V batteries have a unique rectangular shape and are used for devices that demand high voltage and lots of energy.
A rechargeable battery's life is dictated by the number of full or partial charges it could take until it starts to deteriorate and be rendered unusable. A good battery could have at least 600 to 1500 charge cycles before it dwindles to 70% of its initial strength.
The best way to know the rated cycle is to check the product claims of a brand manufacturer. Some would offer from 300 up to 1000 cycles, while pricier options could reach up to 2000 times of recharging.
Across all battery types, self-discharging is common and is a universal fact. For example, a NiMH rechargeable battery loses 1% of its stored power daily when not used. It occurs because of the internal chemical structure that creates a reaction. It reduces the charge even without any connections between the electrodes.
Low self-discharge batteries, sometimes known as ready-to-use or pre-charged, are modified to retain their charge better, even when not used or stored for longer periods. However, some manufacturers would declare that their products will hold 70-80% of their charge for a year and demand a higher price, so it's better to check these claims before purchasing.

Panasonic's Eneloop AA battery is among the world's best when it comes to rechargeable batteries. It is a Nickel Metal Hydride battery ready to use upon purchase and could hold its initial charge at 70% for up to five years. The battery uses a specially designed alloy that can hold the hydrogen firmly, contributing to its low self-discharge.
In terms of cost-effectiveness, its ability to get charged up to 2100 times will definitely cut the cost of purchasing single-use batteries now and then. Another great thing about it is that it can retain its voltage when stored at any given temperature. Use it to unleash the full potential of your digital camera and get four times more shots than alkaline dry cells.
A D-size battery is the standard size of a "dry cell" battery, and because of its ability to hold more power, it is primarily used on utility flashlights or torches. EBL's rechargeable D battery is a good replacement for conventional or NiCd types. It uses NiMH material that performs better than other batteries because it doesn't have a memory effect.
These batteries can be charged using smart chargers and universal chargers as long as they are compatible with NiMH rechargeable batteries. In terms of longevity, you can also rest assured that these batteries can still hold up to 90% after a year of use and 80% even after 3 years of use.
These rechargeable batteries from Energizer are the most expensive ones on this list but with good reason. Aside from hailing from a leading brand known for its high-quality batteries, these batteries and their dedicated charger have many great features, such as versatility, flexibility, and safety.
Firstly, the charger is compatible with both AA and AAA batteries, saving users money as there won't be any need to buy a separate charger for a different battery type. Secondly, you can charge four batteries simultaneously in just 5 to 11 hours with the charger. Lastly, it also has an automatic shut-off feature which activates once all batteries are fully charged.
If you own an Instax camera and don't want to spend money on disposable batteries for the rest of your life, then investing in good-quality rechargeable ones is a great idea. This product from Cauil is perfect for that, as it is compatible with a wide range of Instax models, including the mini 25s, mini 50s, mini 55i, and more.
For less than P500, you are getting a pair of CR2 batteries and a battery charger with an LED indicator. There are two options for charging the batteries: plugging the charger into an outlet using a charging adapter or connecting it to a power bank with 5V output.
Kaizen Philippines is a local supplier of LED light, power supply, and batteries in Manila. Their Nickel-Cadmium Type C rechargeable battery, also known as R14s, is best used for remote controls, clocks, radios, toys, or torches. It holds a nominal voltage of 1.2 with a 2750mAh capacity and is already precharged out of the box with a plastic holding case.
Unfortunately, the manufacturer didn't provide enough information on whether it has low self-discharge or the number of charging cycles. Some reviewers, though, have pointed out that the length of the battery is a little longer than disposable Type C batteries, such as Eveready, yet the diameter is the same.
The features of Panasonic's Eneloop AAA rechargeable battery are almost the same as its AA variant except for the capacity. It still holds a 1.2 voltage with up to 2100 charging cycles. The cells also use Ni-MH internals and are pre-charged when purchased. All you need to do is remove it from the packet and use it.
The Eneloop AAA rechargeable battery also doesn't suffer from the "memory effect," where a battery gradually loses its maximum energy capacity when repeatedly recharged after being only partially used. In fact, it can hold up to 70% charge even after using for a decade!
Some vaping mods require 26650 batteries for more prolonged use at a higher capacity. LiitoKala's rechargeable Lithium-ion battery is the right choice for that task. It can work on a wide voltage range of demand at 2.75 - 4.2 volts with an internal resistance of 20 Ohms. It also doesn't have a memory effect and can be used on different devices.
The LiitoKala brand is under XLS company from China, which started as an OEM supplier of battery chargers. They started battery production with the LiitoKala brand to supply unconventional battery sizes and chargers in the market. The wide voltage range makes it a very versatile battery that accommodates multiple electronic devices.
Protective features against overcharge, discharge, temperature, and short circuits are necessary when buying batteries that will last in the long run. This 9V rechargeable battery from Beston offers that and more, including output over-voltage and output overcurrent protection to guarantee safety and long-term use.
To charge, simply plug it into a power source that can handle 650 mAh through its micro USB port. It has an LED indicator to let you know when to unplug. Regarding durability, the manufacturer promises up to 1000 charging cycles before any significant changes in the batteries' performance.
No battery charger? No problem! Here's an ingenious AA rechargeable battery that can be charged via a USB port on a laptop or a smart device adaptor. It works like a regular AA battery which draws out 1.2V and power up devices like RCs, MP3 players, flashlights, and other toys.
It has a LED light indicator while charging, which turns off whenever the battery is already fully charged. However, it is highly recommended to do an initial charging before using it for the first time, as it can take about five to seven hours.
Palo's 9-volt rechargeable Lithium-ion battery works like most nine-volt Zinc-Carbon types. It could be the best replacement batteries for walkie-talkies, metal detectors, or electric guitars. It has multiple protective features for overcharging, over-discharge, over-voltage, over-current, short circuit, and reverse polarity.
The best feature of this rechargeable battery is its ability to be charged via a micro-USB connection and be fully charged in just 1.5 hours. You can eliminate the need for a bulky dock charger and just connect the battery to any standard USB charging adapter. This may be the handiest 9-volt battery on the market today.
Below are some of the most asked questions on the web answered by the mybest team.
If you find yourself constantly using batteries or if you have invested in a device that requires batteries, rechargeable batteries are definitely worth it. If you have one, you don’t have to worry about buying new batteries for the same device anytime soon since you can recharge them about 500 to 2000 times.
Rechargeable batteries last longer than regular batteries because they can be charged after you’ve completely used up one cycle. However, each rechargeable and regular battery cycle might differ according to their battery capacity. Some regular batteries may have a longer lifespan, but you cannot use them again after one cycle.
Carrying a power bank when going out is always a good idea. But if a power bank is not available, you still have the option to use a charging dock or a USB-C hub to charge your modern smart devices. Check out some of our recommended brands on the links below.
