Rechargeable alkaline batteries are a relatively new type of battery. They are essentially the same as regular alkaline batteries, with the exception that they are marked "rechargeable" on the label. These batteries have the potential to be recharged twenty or more times without the need for electrolyte. They are available in D, C, and AA sizes, and can be used for devices such as radios, toys, flashlights, and portable TV receivers. They are slightly more expensive than the carbon-zinc type, but they are well worth the extra money.

Charge rates
When compared to standard alkaline batteries, rechargeable alkaline batteries offer a much lower performance than their standard counterparts. However, they do offer longer shelf life than standard batteries and have impressive recharge cycles. Whether you're using them for emergency lighting, laptops, or portable electronic devices, alkaline batteries are a great choice. They also offer an impressive number of charge cycles, often up to ten times more than their standard counterparts.

Shelf life
A battery's shelf life refers to how long it will last before it begins to deteriorate. The environment in which you store a battery has an impact on its shelf life. Batteries in cold temperatures are more likely to degrade faster than those stored in warm or humid conditions. The quality of a battery also plays a role. A good quality battery manufacturer will produce a battery that lasts longer.

Capacity
Rechargeable alkaline batteries are a good choice for a variety of electronic devices. They have an alkaline electrolyte, typically potassium hydroxide. Alkaline batteries are most suitable for devices with low drain, but high-drain devices can also work fine. But the life of alkaline batteries will be shortened if they are used in high-drain devices. They can also be recycled, though most of them end up in landfills.

Discharge rates
Rechargeable alkaline batteries are rated in C-rates. Higher C-rates mean deeper discharges, which reduce capacity. Lower C-rates occur later because of lower internal resistance losses. Lower C-rates mean the capacity is not completely restored to the battery. These characteristics are often reflected in battery price and performance ratings. For a battery to last a long time, it is important to know the C-rate of your specific model.

Chargers
One of the best features of chargers for rechargeable alkaline batteries is the ability to monitor the charging process. Depending on the size and model, some can charge up to 180 times. Some are able to recharge alkaline batteries up to 75 percent of their original capacity. You can use these chargers with any of your electronic devices. For the best results, use the ones that will detect the type of battery you are using.

Storage cases
A good case to store your rechargeable alkaline batteries is one with a snap-tight lid and a hard plastic body. These are designed to hold up to four AA or AAA batteries, and provide protection while not in use. Many cases feature a hard plastic base that snaps closed and a tab that opens with pressure. They're a convenient way to store batteries, and are ideal for travel or storage.

Cost
Rechargeable batteries can offer significant savings over disposable alkaline batteries. These batteries are ideal for low-drain products like smoke detectors. These batteries are also relatively cheap per unit and can be found in many consumer electronic products. However, rechargeable batteries are not always the most economical choice. These batteries are typically used for long-lasting and constant-discharge applications like remote controls, toys, and video game controllers.
