Both are non-rechargeable AAA batteries. According to Wikipedia, a R03 battery is a zinc-carbon battery with around 540 mAh capacity, but an LR03 battery has almost double the current capacity. So they can replace each other.
The AAA Zinc-Carbon battery (the conventional, throw-away variety) is referred to as R03 in the technical world, whereas the AmazonBasics AAA are Ni-MH rechargeables with the technical designation HR03. They are both the same physical size. The only difference is that zinc-carbon batteries contain toxic substances which can leak into their environment if not disposed of properly, while nickel-metal hydride batteries do not.
These terms are used by manufacturers to indicate the type of material used in the construction of the battery. The number following the term indicates the percentage of zinc in the battery by weight. For example, an R03 battery contains 3 percent zinc by weight.
Zinc-carbon batteries were originally developed by ITT in the 1950s and they remain popular today because of their high energy density compared to other types of batteries (zinc-carbon batteries can hold as much as three times more charge than nickel-cadmium batteries). These days, zinc-carbon batteries are usually labeled as "throw away" or "one use" because they contain toxic materials that can leach out if they are kept in contact with water for a long period of time. Because of this, they should not be disposed of in regular trash cans but instead taken to a special recycling center.
Rechargeable 18650/RCR123A batteries are the best choice for frequently used electronics. However, 3 high-quality AAA batteries (alkaline batteries, not rechargeable NiCd or NiMH batteries) or 2 high-quality CR123A batteries are a more dependable alternative for standby applications. It is recommended to use batteries with similar capacities to prevent unnecessary replacement costs.
The cost of rechargeable batteries is higher than that of alkaline batteries but they will last much longer because there are no toxic chemicals leached out of the battery casing when it is recharged and recycled. The average life expectancy of rechargeable batteries varies depending on how they are used but generally speaking, they can be expected to last at least as long as three months if used for short bursts of activity followed by long periods of inactivity.
There are many different types of rechargeable batteries on the market but they all work on the same basic principle: when the battery becomes depleted of energy, it can be recharged again. This process of repeated depletion and restoration of energy is called "recharging" or "reconditioning". Batteries that can be recharged hundreds or even thousands of times include lithium-ion, zinc-carbon, and iron-phosphate batteries. Other batteries are considered disposable after a certain number of charges and should not be reused without first removing the toxic materials from their casings.
There are no distinctions between CR123 and CR123a batteries. They are the same size, however their names differ because CR123A is the most popular. Avoid using Ultralast. These batteries are not designed for medical applications.
CR123 batteries are available in 0.5- and 1-amp capacities. There are also 2- and 4-ohm resistors that can be used in place of or with the batteries. The latter option is useful if you need to conserve power when charging cell phones or other devices that use lithium batteries.
It's best to avoid buying generic batteries online. They may look identical, but they could be different sizes so they will not fit your device properly. Also, check that the label does not contain any warnings about allergies to acid or metals before purchasing them.
If you have an old radio or other electronic device that uses CR123 batteries, then you should know that they are becoming increasingly difficult to find. This is due to manufacturers replacing them with batteries that are deemed more reliable and/or capable of storing more energy. However, this doesn't mean that your device cannot be repaired; it's just going to cost you a little more than buying new.
Batteries can be difficult to work with because they break down over time due to exposure to heat and cold.
Other names for the A23 battery include 8LR23, 23A, ANSI-1181A, V23GA, 8LR932, 23AE, L1028, GP23A, and MN21. You can see that different batteries have the same voltage, so why can't they be the same size? Despite the fact that the voltage is the same, the current capacity varies. The A23 has 2.5 milliamperes (mA) of current capacity while the AAA has 1 mA. This means that you can use more than twice as many A23 batteries as you would regular AA batteries in equivilant circuits or devices.
The A23 battery is used mostly in portable devices such as cell phones, PDAs, and other small electronics. They are also used in some automotive applications such as anti-lock braking systems (ABS).
A battery's ability to deliver current over time is called its "capacity". The term "depth of discharge" (DOD) is used to describe how much current can be delivered by a battery before it becomes ineffective. Most batteries have a specified maximum depth of discharge before they stop delivering current. Regular old-style AA batteries can be put into devices without causing damage provided they are not discharged further than 50% of their capacity. A23 batteries should not be discharged below 30% of their capacity because that will reduce their life span.
A battery's chemical reaction when charging and discharging occurs inside the battery chamber is called "discharge".
These batteries are ideal for small devices that do not require a large capacity battery.
Batteries LiR2450 3.0V rechargeable vs. CR2450 Because they have the same (similar) output voltage that never exceeds 3.0 volts and pose no hazard to sensitive circuits, LiR2450 batteries can be used as a straight replacement for CR2450 batteries. They are not intended to be swapped in or out during use though so care should be taken not to mix up packs of one type with another.
CR2450 batteries are still available from some battery suppliers but they are becoming increasingly difficult to find. There are now generic replacements on the market called LBRA2450 which are made by LG. These batteries are almost identical to the original CR2450 in size and shape and provide reliable service when used with LG appliances.
It is important to note that although LiR2450 batteries are a good substitute for CR2450 batteries, they will not last as long under heavy load conditions. This is because their maximum capacity is only 24 milliamps while the CR2450's maximum capacity is 50 milliamps. So if you need batteries that can handle more powerful lights, cameras or other devices then you should get lithium batteries instead.
What's the Distinction Between AA and AAA Batteries?
|AA battery||AAA battery|
|Longer and wider||Smaller in size|
|Usually, last long hours due to its storage capacity||Runs out of faster due to its size|
|Used for bigger toys and other equipment||Used in a smaller and more portable device|
