While most listings will be perfectly trustworthy, there are a few bad apples, so before you hit that Buy Now button, remember this life lesson: if it sounds too good to be true, it probably is.Your problem is not current, it's voltage. Since Amazon accepts sellers from around the world, this isn’t something to be afraid of, but you should always read the reviews. Amazon is filled with rechargeable batteries from companies you’ve likely never heard of. The final thing to consider is the reputation of the battery manufacturer.
A good battery will have a lifespan of 500 cycles at minimum and preferably 1000+. The more cycles the battery is rated for, the better. The third thing to keep in mind is the expected lifespan of the batteries, usually rated in recharge cycles. Be sure to use a calculator when comparing between different lithium-ion batteries. Be aware, lithium batteries are often rated in milliwatt hours, which can make their capacities seem larger than they really are. Other batteries use Lithium, similar to those in your smartphone, and avoid this but at a higher price. This makes the batteries more affordable but their power output drops the weaker the battery becomes. Most rechargeable batteries use Nickel-Metal Hydride (Ni-MH). Along with that, you need to consider what type of battery will best match your needs. As a rule, you’ll want to buy the highest milliamp hour battery you can afford. A remote control car will drain your batteries far faster than an Xbox One controller, for example. How long that battery will last depends on its milliamp rating and how much power the device requires. It is most frequently rated in milliampere/milliamp hours (mAh) and reflects how much charge the battery can hold. Here’s a quick breakdown of what to look for when purchasing rechargeable batteries. What To Look for in Rechargeable BatteriesWhen shopping for rechargeable batteries, there are a handful of key things you’re going to want to keep in mind: capacity, battery type, lifespan, and the reputation of the manufacturer.
