You’ll need 2.5 volts and 4.5 volts.
How can I get a new battery? If I own a battery, how can it be replaced? Or will it be destroyed when I’m done?
The battery you have is a “fixed base” battery. What does that mean? When you buy a battery, it’s going to be there for the rest of time (even if you charge it up), and it has to be replaced every 12 months or so. In most cases that makes it about 25 YEARS. There are a few “factory warranty” batteries that have some life left on the battery, you have to see the manufacturer’s manual for details.
Many new batteries are being replaced at an incredible rate. So, most battery companies offer a lifetime warranty for their batteries. This is actually a very good thing for your investment. The older batteries run much slower and the new batteries last longer.
A few companies offer a longer warranty than one year, and a few offer a full 100-year warranty. The lifetime warranty also takes into consideration the type of battery you buy. For instance there is a Lifetime Lifetime Li-ion Battery with a 70 year warranty, then there are other Li-ion cells that have a 10 year warranty and these also only last a 3 months. There is no one-size-fits-all to the lifetime warranty rules.
If you’re looking to replace the battery in a cell phone, then you should look up the current lifetime warranty, or look up the warranty for all of the cells in your phone.
How do I charge it? The cells that come in your new battery are the same ones used in your older cell phones, so if you’re using the old cell phones then your old NiCd cells aren’t going to be compatible. All cells must be the same. You can’t use an old cell phone’s cells and an iPhone’s cells if you want to charge an iPhone.
But, if you do use your old cells then your iPhone’s cells can work just fine.
Is it always possible to replace a cell phone battery with a new cell phone cell?
Usually. But you’ll want to make sure that the type of battery you are replacing has a proper charger and is NOT “battery killer”. If you’ve used your iPhone’s battery for a while without an external battery charger, then you’re probably safe. But if you’ve only ever used the iPhone’s batteries
