Canon BG-E3 DSLR Battery Grip review
After sold out the EF-s 18-55mm, I intend to buy a tripod, but finally meet someone sell BG-E3, the price is reasonable, so I put away the tripod temporarily to seize this rare opportunity. Most of the person can not understand that why want to buy a battery grip? The price is expensive, and seems not valuable, I also hesitate for a long time before I buy it. After I use it, I found the battery grip is really very useful.Now there are many battery grips in the market as Canon BG-E3 BG-E5 BG-E2N, Nikon MB-D40 MB-D80 MB-D200, Sony VG-B30AM and So on.Compared with BG-E3 350D, the machine performance improvement can be listed as follows:
Add the vertical photo function. It is quite suit for me, as I prefer to take photo vertically, previously, I have to hold up my hand to take photo, it is not only tried but also difficult to hold stable, the success rate is low, and arm is sore, if the camera lens is heavy, it Is easy to be disabled.
Increase the machine body hand feel. As the body design is very small, little finger has no place to put, it is often emerge un-stable situation, if with a grip, it will be more stable.
Enhance the power. 350d is quite power saving, according to my own using experience, it mainly can take around 400pcs photos, and the battery will show low power when it remains 20% power, but if the photo capacity is quite large and without charger, it is bad, BG-E3 can use 2pcs NB-2LH battery to supply power, the duration ability enhanced a lot, besides, if it is still not enough, then you can use 6pcs AA battery to take photo to solve the power shortage problem.
Enhance the brightness degree. It is due to your own psychological effect, after install the battery grip, it is brighter, but also heavy, the machine body and camera lens weight increase to 1200g, it seems like that I have to take more exercises, as the good photo not only need excellent technique but only healthy body. ===================================BG-E3======================================

Battery Performance
NOTE: For information about the Dell? warranty for your computer, see the Product Information Guide or separate paper warranty document that shipped with your computer.
For optimal computer performance and to help preserve BIOS settings, operate your Dell portable computer with the main battery installed at all times. One battery is supplied as standard equipment in the battery bay.
NOTE: Because the Dell 6400 battery may not be fully charged, use the AC adapter to connect your new computer to an electrical outlet the first time you use the computer. For best results, operate the computer with the AC adapter until the battery is fully charged. To view battery charge status, click the Start button, click Control Panel, double-click Power Options, and then click the Power Meter tab.
Battery operating time varies depending on operating conditions.
NOTE: Battery operating time (the time the inspiron 1720 battery can hold a charge) decreases over time. Depending on how often the battery is used and the conditions under which it is used, you may need to purchase a new battery during the life of your computer.
Operating time is significantly reduced when you perform operations including, but not limited to, the following:
Using optical drives
Using wireless communications devices, PC Cards, or USB devices
Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as 3D games
Running the computer in maximum performance mode.
NOTE: It is recommended that you connect your computer to an electrical outlet when writing to a CD or DVD.
You can check the Dell D620 battery charge (see Checking the Battery Charge) before you insert the battery into the computer. You can also set power management options to alert you when the battery charge is low (see Configuring Power Management Settings).
CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the Dell D630 battery only with a compatible battery purchased from Dell. The battery is designed to work with your Dell computer. Do not use a battery from other computers with your computer.
CAUTION: Do not dispose of batteries with household waste. When your battery no longer holds a charge, call your local waste disposal or environmental agency for advice on disposing of a lithium-ion battery. See "Battery Disposal" in the Product Information Guide.
CAUTION: Misuse of the Dell D620 battery may increase the risk of fire or chemical burn. Do not puncture, incinerate, disassemble, or expose the battery to temperatures above 65°C (149°F). Keep the battery away from children. Handle damaged or leaking batteries with extreme care. Damaged batteries may leak and cause personal injury or equipment damage.
Checking the Battery Charge The Dell QuickSet Battery Meter, the Microsoft Windows Power Meter window and icon, the XPS m140 battery charge gauge, and the low-battery warning provide information on the battery charge.
Dell? QuickSet Battery MeterIf Dell QuickSet is installed, press
to display the QuickSet Battery Meter. The inspiron e1705 Battery Meter displays status, battery health, charge level, and charge completion time for the battery in your computer.
Microsoft? Windows? Power MeterThe Windows Power Meter indicates the remaining 40D battery grip charge. To check the Power Meter, double-click the icon on the taskbar.
If the computer is connected to an electrical outlet, a icon appears.
Charge Gauge
Before you insert a DV1000 battery, press the status button on the battery charge gauge to illuminate the charge-level lights. Each light represents approximately 20 percent of the total battery charge. For example, if the battery has 80 percent of its charge remaining, four of the lights are on. If no lights appear, the battery has no charge.
Health GaugeThe battery operating time is largely determined by the number of times it is charged. After hundreds of charge and discharge cycles, DV2000 battery lose some charge capacity, or battery health. To check the battery health, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition, and more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, less than 60 percent of the charge capacity remains, and you should consider replacing the battery. See Specifications for more information about the battery operating time.
NOTICE: To avoid losing or corrupting data, save your work immediately after a low-battery warning. Then connect the computer to an electrical outlet, or install a second battery in the media bay. If the battery runs completely out of power, hibernate mode begins automatically.
A low-battery warning occurs when the battery charge is approximately 90 percent depleted. The computer beeps once, indicating that minimal battery operating time remains. During that time, the speaker beeps periodically. If two DV4000 batteries are installed, the low-battery warning means that the combined charge of both batteries is approximately 90 percent depleted. The computer enters hibernate mode when the battery charge is at a critically low level. For more information about low-battery alarms, see Configuring Power Management Settings.
Conserving Battery Power
Perform the following actions to conserve battery power:
Connect the computer to an electrical outlet when possible because battery life is largely determined by the number of times the battery is used and recharged.
Place the computer in standby mode or hibernate mode (see Power Management Modes) when you leave the computer unattended for long periods of time.
Use the Power Management Wizard (see Configuring Power Management Settings) to select options to optimize your computer's power usage. These options can also be set to change when you press the power button, close the display, or press.
Charging the Battery
NOTE: With Dell? ExpressCharge?, when the computer is turned off, the AC adapter charges a completely discharged Dell 1300 battery to 80 percent in about 1 hour and to 100 percent in approximately 2 hours. Charge time is longer with the computer turned on. You can leave the battery in the computer for as long as you like. The battery's internal circuitry prevents the battery from overcharging.
NOTE: If you want to use a 9-cell inspiron 1300 battery to obtain Dell ExpressCharge, you need to use it in conjunction with a 90-W AC adapter.
When you connect the computer to an electrical outlet or install a battery while the computer is connected to an electrical outlet, the computer checks the battery charge and temperature. If necessary, the AC adapter then charges the battery and maintains the battery charge.
If the battery is hot from being used in your computer or being in a hot environment, the battery may not charge when you connect the computer to an electrical outlet.
The Dell 6000 battery is too hot to start charging if the light flashes alternately green and orange. Disconnect the computer from the electrical outlet and allow the computer and the battery to cool to room temperature. Then connect the computer to an electrical outlet to continue charging the battery.

Laptop battery cant charge
Laptop battery cant charge
Hi guys, maybe we always face this situation: you own a Inspiron 6400 notebook for your business and work. you have finished work which must be reviewed by your customer or BOSS tomorrow, you accidently left your laptop in sleep mode and the inspiron 6400 battery discharged completely, then you charge your battery with AC charger, aslo your notebook OS reports that it is charging. After one night, you want to take your laptop to office, but the GD761 battery shows it is at 0% state-of-charge.
You try to charge it many times, but not work, that means your laptop battery cant charge. Why your laptop battery cant charge, it is caused by your laptop or your laptop battery or your AC adapter?
First : Try cleaning the contacts metal on the battery. Ensure that your notebook's power adapter connect the power, another paragraph has been connected with the notebook, and if the problem is not resolved. Would suggest that you remove the KD476 or TD347 battery power adapter only through your computer.
If you can not restart the computer, it should be a problem with power adapter, I suggest you replace the adapter.
Also if your battery is very hot when charging, it maybe cant charge. You'd better take the GD761 or TD347 battery out of laptop. After 1 hours, the battery temperature lower, then installed the battery to the laptop and charging.
There will be a large voltage electricity when charging the battery and plug in/out battery. The interface client often spark. In that time it is very easy to break the a1189 battery and mainborad. Generally the laptop battery cant charge after too many plug in/out times. So you should turn off your laptop when plug in/out battery.
The laptop battery also have a automatic battery protection CMOS chip to prevent over-discharge and other wrong operation. Some times the CMOS chip will automatically start the automatic protection and lock the battery to forbid charging. So you must store your battery in a cool dry area for about 3-5 days to unlock the battery. If it is cant work you must send your battery to repair center or change a new laptop battery.
Usually you must calibrate your battery every two months. You will find some useful info about How to calibrate your laotop battery here.
Please notice this : Take care of your battery, dont over charge-discharge your battery too many times. You'd better charge your battery at about 20% state-of-charge and store it at about 40% stat-of-charge.

Canon BG-E3 DSLR Battery Grip review
Canon BG-E3 DSLR Battery Grip review
After sold out the EF-s 18-55mm, I intend to buy a tripod, but finally meet someone sell BG-E3, the price is reasonable, so I put away the tripod temporarily to seize this rare opportunity.
Most of the person can not understand that why want to buy a battery grip? The price is expensive, and seems not valuable, I also hesitate for a long time before I buy it. After I use it, I found the battery grip is really very useful.Now there are many battery grips in the market as Canon BG-E3 BG-E5 BG-E2N, Nikon MB-D40 MB-D80 MB-D200, Sony VG-B30AM and So on.
Compared with BG-E3 350D, the machine performance improvement can be listed as follows:
- Add the vertical photo function. It is quite suit for me, as I prefer to take photo vertically, previously, I have to hold up my hand to take photo, it is not only tried but also difficult to hold stable, the success rate is low, and arm is sore, if the camera lens is heavy, it Is easy to be disabled.
- Increase the machine body hand feel. As the body design is very small, little finger has no place to put, it is often emerge un-stable situation, if with a grip, it will be more stable.
- Enhance the power. 350d is quite power saving, according to my own using experience, it mainly can take around 400pcs photos, and the battery will show low power when it remains 20% power, but if the photo capacity is quite large and without charger, it is bad, BG-E3 can use 2pcs NB-2LH battery to supply power, the duration ability enhanced a lot, besides, if it is still not enough, then you can use 6pcs AA battery to take photo to solve the power shortage problem.
- Enhance the brightness degree. It is due to your own psychological effect, after install the battery grip, it is brighter, but also heavy, the machine body and camera lens weight increase to 1200g, it seems like that I have to take more exercises, as the good photo not only need excellent technique but only healthy body. ===================================BG-E3======================================

It can put 6pics AA battery and 2 pics nb-2lh battery
