The way to care your device’s rechargeable battery

 

Battery is a main source for an electronic devices. Without a battery the device can still be operated by using a voltage adapter. However, when we talk about device mobility, battery is required as the source to supply voltage. There are two common battery types; dry cell battery and rechargeable battery. Dry cell is the battery that is not rechargeable and you should replace a new one once it run out of charge while rechargeable battery is the battery that is able to be recharge. Normally the price for rechargeable battery is more expensive than normal dry cell battery. Therefore we should care the battery well to prevent wasting money buying a new one and indirectly we care our electronics devices.

If you wish to keep your electronic device in a long period of time, you are advised to remove the battery so that it is safe and still usable in future when you open the box. Without removing it, you will see there is something (in blue color this time) on the battery holder as shown in the lower most pictures above. What happen then? Yes…correct..your battery is no longer operate able. Hope this information is useful. Sharing is improving…
