Meter Battery Charger Information

Some Batteries Tips

1. The New Battery Isn’t Charging. Is it defective battery ?

New batteries are shipped in a discharged condition or with very low capacity and must charged before use. We generally recommend an overnight charge (approximately twelve hours). Refer to the user’s manual for charging instructions. Rechargeable batteries should be cycled (fully charged and then fully discharged) three to five times initially to allow them to reach their full capacity. (Note: it is normal for a battery to become warm to the touch during charging and discharging).

Note:
New batteries are hard for the device to charge; they have never been fully charged and are therefore “unformed”. Sometimes the device’s charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don’t worry; it’s perfectly normal.

2. How to discharge and charge laptop battery ?

A typical charge and discharge cycle is as follow:
1. Install your newly purchased battery into your laptop
2. Disconnect the AC adapter and use your laptop until it itself shuts down. In this situation, the battery is fully discharged.
3. Connect the AC adapter and your battery should start charging.
4. Charge until the battery is full.
Repeat this charge and discharge cycle a few times and your battery pack will be conditioned to perform at full capacity.

Note: Please do not overdischarge and overcharge your battery.

(2).Take out your battery and slide it into your battery charger.

(4). Fully charged and fully discharged or “cycled” as much as five times to condition them into performing at full capacity.

4. If your battery can not charge with our battery charger, what is matter with the charger?

(3). Your can release the top charging plate by pushing the hooks with two fingers.

(8). Re-connect the DC adapter and your charger should work.

Good luck and if there is still other problem, please don’t hesitate to send us a mail again.

5. What does the light indicator mean when charging battery ?

(1).Plug the AC power adapter in a wall outlet.
(2). Connect the AC Power adaptor supplied with charger to the DC in jack.
(3). “Status” indicator shows RED when the charger is ready and “Charger” indicator shows flashing Green when waiting for battery pack.
(4). Slide battery pack in the charger and “Charger” indicator goes RED when charging.
(5). “Charger” indicator show RED and GREEN alternatively when battery pack has more than 90% charged.

8.The laptop battery still reports 7 minutes of life when it is 100% charged, but the battery actually lasted about 2.5 hours. Are the internal electronics of this battery (the part that reports status ) are okey ?

New laptop battery has a self recognise process for the first time charge . After using a period of time, it will become normal.
Please set the minimum capacity for the computer to turn off in the power meter management. Disconnect the AC adapter and use your laptop until the battery is fully discharged. Then connect your ac adapter to fully charge the battery. Fully discharge and fully charge the battery or cycled about 3 to 4 times to condition the battery to its full capacity.

9. What are smart batteries?

Smart batteries have internal circuitry which monitors the battery condition which is displayed on a fuel gauge to indicate the remaining charge .

11. What is memory effect?

A condition that occurs when a battery is charged to the same level several times consecutively. The battery develops a chemical “memory” of that level and will not allow a charging past that point. You can avoid this through several complete discharge and recharge cycles.

12. We often meet this question “I have discharged the battery to zero volts, and fully discharge and fully charge as your instruction, but the battery can not charge to 100% capacity.” It is involved with overdischarge and overcharge .

Our battery pack is made up of several cells. If you discharge the battery to zero, what will most likely happen is that one or more of the cells will “reverse” because they are weaker than the other cells. The reversed cell begins to accept a “backwards” charge from the other better charged cells around it. This will kill the battery. So we should stop the discharge at one point, rather than letting the pack slump down to zero volts.

In the meantime, when the battery is at its full capacity, we should not plug the AC adapter to trickle charge the battery. It will overcharge the battery.
Note: Overdischarge and overcharge the battery will damage the battery.
