After several years, even the best types of rechargeable batteries will need to be replaced. Each kind of rechargeable battery has a fixed number of discharge and recharge cycles that it can endure under the best conditions, and if it is not maintained properly, it can endure even fewer cycles, reducing its lifespan significantly.
When it is time to replace a rechargeable battery, there are several important specifications that must be followed in order to find the proper battery for your device. This includes things like the physical size of the battery, the type of battery and the capacity.
Here are the most important specifications to look for when buying a Power Sonic battery to replace the current battery in your device:
#1 Type Of Battery
Today's rechargeable batteries are available in several common types, including sealed lead acid, or SLA, nickel cadmium, or NiCad, nickel metal hydride, or NiMh, lithium iron phosphate, or LiFePO4, and lithium ion, or Li-ion. In some applications, NiCad and NiMh batteries may be used interchangeably, because they have similar voltage, capacity and charging requirements, but as a rule, a new Power Sonic battery should be the same type as the original rechargeable battery.
Because each type of rechargeable battery uses different chemicals or materials for the electrodes, the plates and the electrolyte, they will have different charging characteristics for each type of cell, differing capacities, and different voltage requirements. Using a battery of the incorrect type in your device may cause damage to the device, its charging circuit, or to the battery itself, voiding the warranty of the battery or the device and possibly leading to dangerous conditions such as overcharging and overheating the batteries, increasing the risk of fire.
Make sure that your new Power Sonic battery is of the same type as the old one, SLA, NiCad, NiMh or LIFePO4, and make sure to follow the manufacturer's instructions for replacing the battery in your device.
Each type of rechargeable battery has a specific voltage rating, and in all but a few very specific cases, your new Power Sonic battery should be the same voltage as the original. SLA batteries are often 2, 4, 6, 8 or 12-volt, while NiCad or NiMh are often found in voltages of 2.4, 3.6, 4.8, 6, 7.2 and 12.
In an SLA battery, each cell makes 2 volts, and it is wired in series with other cells to create batteries with higher voltages. For instance, a 12-volt battery is made from six 2-volt cells. NiCad and NiMh batteries are about 1.2 volts per cell, requiring five cells to create a 6-volt battery or 10 to make a 12-volt battery.
In general, the voltage of the replacement battery should match the original, because a battery of a different voltage may cause damage to the device or the battery itself. In some applications, however, such as electric wheel chairs, two 6-volt SLA batteries may be wired in series to create 12-volt system, or two 12-volt batteries may be wired in series to create a 24-volt system. In other cases, such as laptop computers, the input voltage can be a little different from the nominal voltage, and the part number will become the most important factor in determining the type of replacement battery to acquire.
Be sure to find the voltage specifications and read the manufacturer's recommendations before choosing a new Power Sonic battery for your device. It is important to note that these are nominal voltage ratings. For instance, a fully-charged 12-volt SLA battery can measure as high as 12.8 volts with a voltmeter, which is normal, and is considered completely discharged when the voltage falls below about 10.5 volts. It is best to avoid discharging an SLA battery below 12.18 volts or 50 percent to achieve maximum lifespan.
Capacity for most rechargeable batteries is measured in either milliamp-hours, mAh, or amp-hours, Ah. An amp-hour is a measurement of the amount of current that a battery can provide over a given time. For instance, a battery rated 100 amp-hours could provide 2 amps for 50 hours, or 20 amps for 5 hours, theoretically, and 1000 milliamp-hours equals 1 amp-hour.
In general, when buying a new Power Sonic battery, you would want a similar capacity as the original battery. Often, you will be able to find the same exact capacity, which is ideal in most cases, but if you cannot, it is best to choose a higher capacity if everything else is the same.
In some cases, it is possible to upgrade your battery by buying one with a larger capacity. Typically, these batteries will be physically larger than those of the original capacity, so it is important to make sure that they will fit your device properly by taking note of the caliphs dimensions of the battery. For instance, AA-sized NiMh cells rated at 2800 mAh are slightly thicker than 2400 or 2000 mAh batteries, and because of their larger diameter, they may not fit in devices designed to use the thinner standard AA batteries.
The size of your new Power Sonic battery can be just as critical as the other specifications, especially if you are getting a battery with a higher capacity than the original. Make sure the typer and size match the original, a well as the physical dimensions.
There are several standard battery sizes, including common ones like AA, AAA, C, D, and 9V, as well as several custom NICad or NiMH battery pack sizes. For large SLA batteries, there are also standard group sizes, including groups 24, 27, 31, as well as 4D and 8D sizes and GC batteries, or golf cart batteries.
While two batteries from the same size group may be relatively close in size, there may be some variation, such as the differing diameters of AA NiMh batteries that are available. To be absolutely sure you have the correct battery size, look at the physical dimensions closely.
By following these specifications closely, you can find the best Power Sonic battery for your device, ensuring compatibility and a long lifespan.
