About this deal

Boots MN21 12V alkaline batteries are ideally suited for car alarms and may also be used with all other devices which take this size of battery. While much rarer than AA and AAA counterparts, 23A batteries are still fairly commonplace in certain appliances and gadgets. However, it can be difficult to know what you actually need, since they go by many different names. The higher the discharge current, the lower the capacity. For example, the power drops to about 43 mAh at 5 mAh and plummets to 26 mAH at 15 mAh. On the bright side, the output voltage remains above 9 volts for about 90% of the operating time. These features make it ideal for powering multiple devices. A23 Vs. Other Similar Batteries In Comparison: Are They Interchangeable? A23 Vs E90 It is not a big problem if you plan to install the A23 for low-voltage devices, such as, entry remotes, flashlights, or smart keys. Most devices work at their best as long as the battery fits with the compartment.

Regarding chemistry, A23 belongs to the category of non-rechargeable alkaline batteries. This battery type often appears in small electronic devices such as Bluetooth headsets, video game controllers, cameras, keyless vehicle entry systems, etc. Alkaline batteries can sometimes leak a substance called potassium hydroxide which is a caustic agent that can cause eye, skin and respiratory irritations. This risk is reduced by not mixing different manufacturer battery types, batteries of different chemistries and by the replacement of all batteries at the same time. The 12V units are able to power all your smaller compatible gadgets for roughly 100 hours, though, like with others, it's about how you use them. The Energizer A23 battery, with non-rechargeable alkaline cells, enters the market as a leading Duracell competitor. Its nominal capacity reaches 50 mAh tested with a 20 kΩ resistor at 21°C down to 6.0 volts.If your device is compatible with one of the following battery codes, this is a sign you need one of the 12V alkaline power sources: 23AE, GP23A, V23GA, LRV08, 8LR932, 8LR23, MN21, L1028 or ANSI-1181A. How can you spot a 23A battery? Below, we'll answer a few key questions that should help you choose the right batteries for your needs. Do you need a 23A battery? Like us, if you have a drawer full of different, loose batteries, you might already have a 23A battery in your arsenal. Aside from the codes - which are always found on the cell itself - it can be handy to know exactly what one looks like. The A23 and N-cell (E90) batteries possess relatively similar physical dimensions. The former is 10.3 x 28.5 mm, while the latter is 12 x 30.2 mm. Another similarity is that both belong to the wide category of alkaline batteries.

The A23 battery is close in size to the N battery, which has a voltage of 1.25 V to 1.5 V. It is also similar to the A27 battery, which has the same 12 V nominal voltage and almost the same length but is smaller in diameter by about 20%.

The actual performance depends on a wide range of factors, such as temperature, lifespan, or discharge current. These two are nearly identical in both size and internal construction. The dimension of A27 is 8.0 x 28.2 mm, or in other words, its diameter is slightly smaller than A23.

Waste batteries can be returned to our stores free of charge, using the small waste battery bin in store. Batteries should never be put in general household waste or recycling bins. An A23 battery is cylindrical and approximately two-thirds the length of an AAA battery, measuring 28.2mm long and 10.0mm in diameter, with a typical weight of 8 grams. An A23 battery is an 8- cell device with a nominal voltage of 12 V. The higher voltage is necessary for the radio frequency- transmitting and receiving devices which A23 batteries often power. It has a capacity of around 55 mAh. [4] For example, you can warm up “dead” batteries in minutes. The voltage then spikes, and your items gain an extra life. However, it is only temporary, and you should carry out a battery replacement as soon as possible.
