A rechargeable battery (secondary batteries) can gain power as many times as possible as opposed to the other batteries. Simply these batteries can be recharged and reused again. These batteries are capable of charging and discharging as many times as it's needed.

All rechargeable batteries have reversible cells that allow the battery to get recharged once it's plugged in in a source of current or electricity. There are various rechargeable battery types some of which include; Lithium-ion, lead-acid, nickel-cadmium, and nickel-metal-hydride among others.

Many rechargeable batteries have some common features and this article will compare different batteries. Crossword clue involves words and letters or phrases that may help narrow out a search to get a rechargeable battery.

Rechargeable Battery Types and Sizes

Batteries are made of different sizes and that according to the devices they are used on. The amount of power they can handle depends on their sizes. The bigger the size of the battery the larger capacity it has for holding energy. The most common battery sizes include; AA, AAA, AAAA, C, D, 9V, CR123A, 23A and CR2032 battery sizes. AAA batteries are the smallest while D size is the largest. Rechargeable battery types include; Lithium-ion, Nickel Metal Hydride, Nickel Cadmium, and Sealed Lead Acid.


Rechargeable battery sizes vary from the power they can handle to the type of device they are used in. As mentioned above, the sizes are AA, AAA, AAAA, C, and D. The sizes get bigger as the alphabet increases meaning a battery with size A is larger than that of D. Other size examples include; CR123A, 23A, and CR2O32. Always remember to check the battery size on the battery before use.

Nickel Cadmium Batteries.

These are good at supplying very high currents. This type of battery uses nickel hydroxide at the positive electrode and in the negative electrode is Cadmium. Its electrolyte consists of Potassium Hydroxide and for that, it's characterized to have low internal resistance which helps it withstand high currents. Nickel Cadmium has a varied range of sizes as those mentioned above.

Nickel Metal Hydride

The major difference between these battery types is the features for example Nickel Metal Hydride contains nickel hydroxide at the positive anode and Hydrogen allow at the negative anode. The electrolyte that is similar to that of Nickel Cadmium is Potassium Hydroxide. The distinguishing feature is that Nickle Metal Hydride unlike Nickel-Cadmium has a higher density in each volume and weight. This type of battery is specifically available in AAA, AA, C, and D sizes.


Lithium-Ion batteries have both their Anode and Cathode as a host for their Lithium Ions. During the charge and discharge process, the ions move in towards the Anode and reverse back to Cathode. Unlike the other two types, the Lithium-Ion battery electrolyte contains a mixture of an organic solvent and dissolved lithium salts. When fully charged, this battery has 4.2v while when fully discharged 3.0 v. The sizes of this battery are many for example we have the 18650 sizes, CR123A, 16340(RCR123), 14500(AA-size), and 10440 (AAA size with a 4.2 V). The 18650 is the most common size of the Lithium-Ion battery used.

Rechargeable Battery Types and Comparison

The best rechargeable battery types are AA and AAA battery sizes because they are affordable, do not produce a lot of waste, and long-lasting. Nickel Metal hydride has a standard voltage of 1.2, has a very high energy capacity, and can be recharged between 150 to 500 cycles. It discharges quickly that is 30% to 40% in a month. This type of battery is commonly used in GPS, digital cameras, toys, and Headlamps among others. Always remember that this battery type needs to charge before use.

Comparison Between Nickel-metal Hydride, Lithium-ion, and Nickle Metal Battery Types

Nickle Metal Hydride and Nickle Metal

Nickel Metal Hydride just like Nickel Metal has a voltage of 1.2, a high energy capacity and can be used for 150 to 500 cycles. It gets discharged at a rate of 20% per six months. Similar to the latter, it's used for GPS, toys, Headlamps, and digital cameras. Unlike Nickel Metal it can be used directly after it's out of the package.

Lithium-ion Battery and Nickel Metal

Lithium-ion rechargeable battery type has a voltage of 3.6 V. Most of the AA and AAA battery sizes of this battery are not widely available. It can be recharged for 300 to 500 cycles. Its rate of discharge is 2% a month. The lithium-ion cab is used in smartphones, sports watches, bike lights, GPS, notebook computers, and various portable power devices among others. Like Nickel Metal, Lithium ions should be charged before use. This battery type however gets ineffective by age and the rate of use.

Always remember that exposure of batteries to extremely high and low temperature interferes with its performance. Also ensure when charging different ages, brands or capacities are not combined rather charge each separately.


Rechargeable Battery Types Crossword Clue

As discussed rechargeable battery types are Nickel Metal, Lithium-ion, Nickel Metal Hydride, Lead-acid, and Nickel-Cadmium. Crossword clue of rechargeable battery types will majorly entail the initials of various batteries for example NICAD. In other words, synonyms of the battery types can be used as crossword clues.

The following are examples of rechargeable battery type crossword clues that may be used to solve puzzles; rechargeable battery type, battery type, battery types in many remotes, small battery type, and metal element used in rechargeable batteries, and battery type in many remotes.

Looking for a crossword clue may need one to know the number of letters in the answer to make the process easy. For example, a clue which is a type of rechargeable battery with five letters may refer to many things. The five letters clue, however, will help narrow down to few specific answers which may include; NICAD this is the most appropriate answer since it's a type of rechargeable battery and its initials are five letters. ANODE still has five letters and it's a word related to batteries. There are other clues or possible answers that can be used.


As discussed various rechargeable battery types have different uses, voltage and come in different sizes. To be in rechargeable crossword clues, knowledge of the various battery types is very essential. It is important to note that the letters in the battery types always refer to the height and width of a battery. The sizes increase from A to D. That means a battery type indicated D is bigger than that of AA or AAA. Most of the rechargeable batteries have a lot in common as discussed e.g., some need to be charged before use while others can be used when out of the package.
