Battery A27 (27A)

When replacing finger batteries, it is important not only to observe the polarity, but also to choose the right battery, which will not differ in technical characteristics. After all, outwardly they can be the same, but they will differ in voltage, it is in this parameter, first of all, you need to select the A27 battery.

Specifications A27

This type of galvanic cell belongs to the “mini-finger” category, therefore it is most often used in devices consuming a small amount of electricity.

The main characteristics:

1. The voltage is 12V.
2. Size - 8 by 28 mm.

Another important parameter that you need to know when replacing the A27 element is the capacity. Despite the fact that with ordinary batteries it is usually not indicated on the device’s case, a high-quality alkaline electrolyte product will have a value of at least 20 mA / h. With this capacity value, with a constant discharge with a current of 20 mA, the battery will last only about 1 hour.

Battery Applications

The A27 battery is used in compact electronic devices in which the operating voltage must be maintained within 12 volts. Such products include:

1. Trinkets for alarm.
2. Walkie Talkies.
3. Remote control panels.
4. Kids toys.
5. Led lights.
6. Digital Watch.

In the listed devices, the A27 battery is most often used in a single copy, but in some models of toys, flashlights and other devices where electric current is consumed more intensively, installation of 2 or more power sources will be required.

Analogs of the element A27

If for one reason or another it is not possible to purchase an original battery, then it can be replaced with an analog.

This category includes:

• GP27A;
• 8LR732;
• L828;
• MN27;
• V27A;
• G27A;
• A27BP

The listed analogues can be successfully used instead of A27. The A23 battery is not analogous, although it has the same voltage, but it is slightly thinner and lighter.

Can I charge the A27 battery

Unfortunately, this type of battery is not a battery. This means that it is categorically not recommended to be charged using direct electric current. Restore the working capacity of the power source using "folk" methods also should not be.

For example, if an ordinary battery can be brought back to life for a while by lightly tapping on its body with a hammer, then when carrying out a similar procedure with A27, you can completely destroy the product, which consists of 8 elements of the disk type LR632 connected in series.

Popular manufacturers and their features

Despite the fact that the products of well-known manufacturers are not cheap, it is recommended, when choosing a new battery, to give preference to the following companies:

• Energizer Products from a well-known manufacturer of alkaline batteries are of unsurpassed quality. Energizer battery life can be several times higher than this for low-cost products.
• Duracell. The batteries of this manufacturer are also not inferior in power to the best samples, and the alkaline batteries of this company can easily compete for first place in this rating in terms of durability.
• Panasonic.The batteries of this manufacturer are well tolerated by adverse operating conditions, so they can be successfully used in devices that are used with constant fluctuations in air temperature.

• Sony The 27A battery from a well-known world brand has a standard voltage, but as for the capacity of the product, alkaline batteries in this indicator are not inferior to products from manufacturers leading this list.
• Varta. The products of the famous German brand are of unsurpassed quality. The product will hold voltage longer, therefore it is ideal for devices whose operability directly depends on the battery charge level.
• Сamelion. A Chinese manufacturer of electrical products, whose products have a decent level of quality. This statement fully applies to the A27 battery.
• Space. The excellent quality of the products of the domestic electronics manufacturer, as well as the relatively low cost of the batteries, make it easy to choose a battery for any electronic device, including which it is necessary to constantly maintain a voltage of 12 V.
• Trophy. Batteries from this manufacturer have the lowest cost, with very decent quality products.
• Robiton A good manufacturer of electronic equipment, including batteries marked A27.
• GP - power elements have a standard form for A27, while the quality of the product is at a very high level.

Any battery from the rating above can be successfully used in any device where the installation of an A27 battery is necessary.

What to look for when purchasing

First of all, when buying a battery, you need to remember how the elements marked A27 differ from A23 in order not to accidentally purchase a battery that is not suitable for installation in an electronic device.

A23 has almost the same length and voltage, but the diameter of the product is more than 2.3 mm. To purchase a quality product, you should also look at the expiration date that is applied to the case. Any battery has a self-discharge current, which means that using the product after the expiration date may be completely impossible.
