Not charging


Hello,

Have try to use another similar charger to charge it to see if it will charge? If you have and yet it did not charge, it means the charger is not the problem.

The problem is the the charging port, the charging port of your phone is bad that is why it is not charging, all you need do is to change the charging port of your phone and you will see that your phone will charge.

Replace the charging port and you will see that the phone will charge.

Take care.

How many pc can i connect with usb connect 881


At least three--that's what I do. I have the 881 docked in a Cradlepoint router with a wireless access point. The 881 provides internet access to all. Been doing it for almost 3 years--no complaints.

Phone not holding charge with new battery


Hello,

Have you try to use another charger to charge and it doesn't hold charge? if yes., no problem because it be that your charger is bad. But since it does not charge with another charger, it means the charging port is bad.

The problem with the phone is the charging port, the charging port of your phone is not charging the phone that is why it doesn't hold any charge,

All you need to do is to change the charging port of your phone and you will see that your phone will hold charge.

Take care.

881 battery is dead. can it be charged or do i need a new battery


You have not mentioned how long the battery has been used. If it has been used regularly and charged frequently over a period of more than year or so then it is advisable that you use a new battery.

Phone won't charge


Hi, The Li-ion battery cahrging circuitary is some what complex. For most chargers, the charging procedure is divided into three main phases: ? Pre-charging phase ? Constant-current-charging phase ? Constant-voltage-charging phase In the Pre-charging phase, it utilizes low charging current to protect the battery. However,in most recharging situations, the charged batteries still have some voltage remaining, so the charger does not need to apply this action, and just passes it on to the next charging phase. The constant current and voltage charging phases are the main charging phase for recharging the batteries, where most of the charging energy is transformed into the battery. The maximum charging current for a battery depends on the battery?s rated capacity. For example, one battery rated 700 mAh usually can be charged at 350 mAh to 400mA, for faster charging effort. When the charged battery is Li-Ion, in the last charging procedure, the microcontroller normally maintains regular charging voltage while monitoring charging current to determine when the charging procedure should be completed. When the battery is fully charged, most of the electrical energy is converted to thermal energy, which can result in high battery temperature. In this case, the temperature monitoring function will be added for the solution. But since most Li-Ion batteries on the market also have an over-charging protection function, the temperature detect function is rarely used. So it is better to get your phone charging circuitary checked at a local store rather than to make a charger,coz both may cost you almost same. all the best my friend. regards sreejith
