There are different kinds of batteries, but they only have one purpose – to make things work. Batteries can be a substitute to electricity. They are the reason why a lot of machines, tools or electronics are portable or handy. The main thing we are looking for in any battery is how long it lasts. So, after careful research and product testing, we are giving you the best battery when it comes to daily home use.

How to Select the Best Battery

Some people may think that the only important thing about batteries is longevity. But, batteries are actually complex objects because they can power up a lot of devices, even high-tech ones. To avoid buying the wrong kind of battery, here are important things to consider before purchasing the best battery for your home devices:

  • Device

    The first thing you have to think about is the device that will use the battery. Five factors must come to mind regarding the device: running time, maximum current drain (A), power consumption or wattage, the amount of voltage needed, and the battery compartment’s size and shape. A battery’s product description also indicates most of this information to know which devices will be compatible with it.

  • Format

    Common household battery formats are AAA, AA and button cells. Clearly, a button cell battery will never fit a device’s battery compartment specially designed for AAs. If you have a new device without batteries included, always check how the battery compartment looks like before purchase.

  • Type

    The two common types of household batteries are rechargeable and non-rechargeable. Never attempt charging a non-rechargeable battery because it may cause electrical and toxic problems. There is also a limit on the number of charges. Some rechargeable batteries can even take two charges only.

  • Rechargeable

    Going further, the popular types of rechargeable household batteries are nickel metal hydride and nickel cadmium (NiCd). Nickel metal hydride comes in custom-sized, small cylindrical, poly-wrapped, 12-volt, 9-volt, D, C, AA and AAA batteries. It is mainly used for small electronic gadgets. It is non-toxic and cannot be spilled. Nickel-cadmium has the same battery formats and compatible devices as nickel metal hydride. The only difference is that cadmium is a toxic metal. You must never burn this type of rechargeable battery.

  • Non-Rechargeable

    On the other hand, non-rechargeable household batteries are commonly composed of zinc air, silver oxide, mercury, lithium, and alkaline with zinc carbon. Zinc air usually comes in custom sizes, 9 volts, and button cells. It is made for watches and hearing aids. Silver oxide is similar to zinc air, but it can be customized into a bigger and more high-powered battery for aircraft.

    Mercury has the same battery formats as zinc air except for the AA size. It is also similar to nickel metal hydride when it comes to toxicity. So, never burn a mercury battery. This type of non-rechargeable battery is useful for cameras.

    The lithium battery is popular in AAA and AA sizes. It is perfect for alarm clocks, keyless car controls, and pacemakers. It is non-toxic, but it must never undergo a short circuit to avoid overheating and explosions.

    Lastly, alkaline and zinc carbon batteries are probably the most popular ones. These batteries usually leak but are still non-toxic. Another benefit from these non-toxic batteries is that they are environment-friendly. Alkaline and zinc carbon batteries are recyclable to be used as fertilizer, road construction materials, and steel base for some products.

  • Capacity

    Battery capacity is represented as mAh or Ah if it is more than 1,000 mAh. The higher the mAh, the longer it can operate a device. The battery’s capacity depends on the device’s running time. It actually has a formula:

    Ah = Device Wattage x Running Time (hours) / Battery Voltage

    For example: If the device requires 12 volts and has 10 watts, and you need to run it for 10 hours, the battery you are finding for must have a capacity of more than 8.3 Ah.

  • Maximum Discharging Current/Rating

    This is usually found on the battery’s product description. It should be higher than the device’s requirement. If you cannot determine the device’s exact maximum current drain, you can measure it with a multimeter.

  • Voltage

    Batteries must have the exact voltage needed by the device. Their voltage can also be a little bit higher.

Summary

Finding the best battery for you actually, relies on its purpose – the device. Obviously, button cell batteries cannot be compatible with devices that need AAA batteries. It is important to always read product descriptions and carefully observe things to make two components such as device and battery compatible.
