Being wireless, Bluetooth headphones require batteries to operate. The headphones get their power supply from batteries and not from direct current via an electric outlet. Needless to say, the batteries are of the rechargeable type.
Batteries are the heart of your Bluetooth headphones and, as a matter of fact, of almost every electronic gadget. If your batteries are dead, then your gadgets have no life and functioning is not possible.
Full-power batteries are essential to your successful use of your Bluetooth headsets. They are particularly critical when you use your gadgets in a production or work environment. When your battery suddenly dies out or runs low in the middle of an important business call, it can cost you a potential client or it can risk a business relationship. You can avoid all the panic and cursing for your battery's not having a long battery life when you need it to.
Taking care of your battery is not really a herculean task, yet many gadget users end up having a malfunctioning battery. Eventually, however, you will be forced to buy and replace your battery when it reaches the end of its life. Choosing the right battery for your headset is pretty much important because if you buy the wrong one, you can potentially brick your gadget.
You have to make sure that your replacement battery is compatible with your headphone model. For example, if you have a Nokia Bluetooth HDW-2 Bluetooth headset, then the Nokia Bluetooth 17AAAH2XZ battery is recommended. It is an NiMH rechargeable battery with a voltage of 24 V and a capacity of 160 mAh. The battery is quite compact and lightweight, too, at a height of 16.5 mm, width of 20 mm, and depth of 10 mm. Another example: the Plantronics Bluetooth 27AAAM2BMXZ, which is an NiMH-type battery with voltage of 2.4 V and capacity of 270 mAh. The replacement battery is just as lightweight and compact as the original of the Plantronics M3000 Bluetooth headset, at 10 mm by 22 mm by 22 mm physical dimensions and weight of 8 grams.
Some of these batteries may only be available in online shops, so it is best to surf the Net. Just make sure that when you buy online, the vendor is reliable and safe because you might purchase an item that is not authentic. If you are not sure with what battery is better to replace for your Bluetooth headphones, it is best to ask to experts and read forums regarding your unit.
