- Q: My new laptop and/or camcorder battery is not working at all! What's up?
New batteries are shipped in a discharged condition and must BE charged before use. We generally recommend an overnight charge (approximately twelve hours) for Ni-Cd batteries and a 24 hour charge for Nickel Metal Hydride. Refer to your computer manual for charging instructions. Rechargeable batteries should be cycled - fully charged and then fully discharged - 2 to 4 times initially to allow them to reach their full capacity. (Note: it is perfectly normal for a battery to become warm to the touch during charging and discharging).
- Q: How do you charge new laptop battery?
When purchasing a new battery, you may find that the battery is at or near 0% capacity. This will be due to the length of time the battery has been in stock and does not affect the quality of the battery. If the battery is at 0%, it may take up to 12 hours of continuous charging or, cycling the battery three times (see the Battery conditioning section below) to wake up the battery. If the new battery still does not have a charge after having been charged for 12 hours or cycled three times, it should be replaced. Standard warranty on all ThinkPad batteries is no more than one year as stated in the Statement of Limited Warranty that comes with the machine or battery.
- Set the power supply option to NEVER to the following:
- Turn off Monitor: Never.
- System Standby: Never.
- System Hibernates: Never.
- Turn of monitor: Never.
- And reset after you have completed the charge and recharge sequence
- Q: What is battery conditioning?
In general, rechargeable batteries store electrical energy through chemical reaction -- therefore, capacity will change by temperature, unused storage period, load condition, and number of cycles used.
- Q: How do you obtain the best battery condition to extend battery rundown time?
Once you have started charging the battery pack, do not use it until it is fully charged.If your battery is brand new and you are charging it for the first time, your battery may not be charged to full capacity due to characteristics of chemicals in the cell. To obtain maximum performance, all chemical materials in the battery must be fully activated. In order to achieve this:
- Cycle the battery (fully charge, then fully discharge) three times.
- Cycling the battery three times is also recommended if you have stored the battery for a few months.
- Do not charge the battery pack until all of its power is used. Partial charge or discharge causes a lack of uniformity of activated chemicals in the cell, and may cause performance degradation.
It is recommended that you deep-discharge your Ni-MH* battery every few months for optimum performance. Deep-discharge occurs when your ThinkPad system is used on battery power until the charge is at 0% (the system will automatically go into hibernation). At this point, attach the AC adapter and charge to 100%.
Note: Do not deep-discharge Lithium Ion batteries. Batteries can degrade when they are left unused for long periods of time. For some rechargeable batteries (particularly Lithium Ion batteries), leaving a battery unused in a discharged state could increase the risk of a battery short circuit, which could shorten the life of the battery and can also pose a safety hazard. Do not let rechargeable Lithium-Ion batteries completely discharge or store these batteries in a discharged state.
- Q: How do I identify my battery?
The first information to provide would be the make and model of the equipment that you require the battery for e.g. Toshiba Satellite Pro 400, or Compaq Presario 1283. There is also usually a label on the battery, and some of the information on the label will help our sales team to identify your battery quickly.This information includes the voltage of the battery pack (note: this is not the same as the voltage on the power supply), the capacity of the battery pack and the chemical construction of the battery pack e.g. Li-ion, Ni-MH or Ni-Cd. This information can be used to ensure the information you have provided matches the information we have about your battery. Many battery packs also have part numbers on the label; this can sometimes be used to help identify the battery. We would suggest that it is best to have all this information written down or close to hand before you call our sales team. This will help us deal with your call in an efficient manner.
- Q: What is the difference between Ni-Cd,Ni-MH,and Li-Ion?
Li-ion (Litdium Ion). This is one of the newest cell types. There are no known problems of memory effect with this battery type and it is the easiest battery type to care for. The downside of this battery is that it has the highest engineering costs and tderefore the price is usually considerably higher than other cell types.
Ni-MH (Nickel Metal Hydride). This cell type is the most common cell type currently available for laptop computers, (altdough Li-ion is rapidly becoming the most popular) this battery type is relatively cheap to manufacture and tderefore tends to be cheaper than Li-ion. This cell type is prone to memory effect,so it is important to take good care of your Ni-MH battery to ensure that you obtain the best runtimes.
Ni-Cd (Nickel Cadmium). This is one of the oldest cell types and is generally only found in older laptops. The main pro for this cell type is its ability to handle higher loads, and tderefore is more commonly found in portable power tools or devices that need a lot of power to work efficiently. The main downside of this cell type is that it is notorious for suffering from memory effect so good care must be taken with this battery type to ensure most effective use of battery.
- Q: How long does battery last?
the life span of a Notebook battery is about 1.5 to 3 years under normal conditions.As the rechargeable battery begins to die, the user will notice a decline in the running time of the battery.
- Q: The rating for battery?
V(olts): the voltage of the new battery should always match the voltage of the original.mAh:It standards for milli-Amp hours (1 mAh=0.001Ah), High amp-hour rating means a longer run-time and will not cause incompatibilities.
- Q: What is memory effect?
Ni-Cd batteries, and to a lesser extent Ni-MH batteries, suffer from what's called the "memory effect". What this means is that if a battery is repeatedly only partially discharged before recharging, the battery "forgets" that it has the capacity to further discharge all the way down. To illustrate: If you, on a regular basis, fully charge your battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of its extra 50% capacity which has remained unused. The battery will remain functional, but only at 50% of its original capacity. the way to avoid the dreaded "memory effect" is to fully cycle (fully charge and then fully discharge) the battery at least once every two to three weeks. Batteries can be discharged by unplugging the device's AC adapter and letting the device run on the battery until it ceases to function. This will insure your battery remains healthy.
- Q: What is a battery cycle?
Cycle life is measured by the amount of times a battery may be charged and discharged. Every time a battery is charged and discharged, it uses one cycle. Cycle life is very important in battery applications such as laptop batteries and emergency light batteries. A Ni-Cd battery has a cycle life of 500-1000 or more cycles.
- Q: What is the difference between USB 1.0, USB 1.1 and USB 2.0?
USB 1.0 can operate at 1.5 Megabits per second (Mbps). battery has a cycle life of 500-1000 or more cycles.
USB 1.1 allowed a maximum transfer rate of 12Mbits/second. USB mice and keyboards need only 1.5Mbits/s to function. That performance level is also named 'USB'. USB 2.0 has a raw data rate at 480Mbps, and it is rated 40 times faster than its predecessor interface, USB 1.1, which tops at 12Mbps. Originally, USB 2.0 was intended to go only as fast as 240Mbps, but then, USB 2.0 Promoter Group increased the speed to 480Mbps in October 1999. You can use USB device with USB 1.0, USB 1.1 and USB 2.0 as long as your PC or laptop has USB ports, but USB 2.0 device transfer data at 480 Mbps on systems with USB 2.0 support only.
- Q: Battery terminology:
- Battery: Two or more cells connected together
- Cell: An electrochemical system that converts chemical energy into electrical energy. .
- Capacity: this is amount of energy a battery cell or battery pack actually provides. The higher the capacity the longer the equipment will run on battery power. Usually measured in Amp hours (Ah) or Milliamp hours (mAh).
- Battery Charge: this is the process of passing electricity into the battery pack so the pack can be used to provide power when the user is away from mains power.
- Li-ion: Litdium Ion. This is one the newest battery types available. It can offer the same power as a Ni-MH battery in a smaller & lighter package. This type does not suffer from 'Memory Effect' but it is expensive to manufacture.
- Ni-Cd:Nickel Cadmium. This is one of the oldest battery technologies that are still in use. Usually found only in older equipment or applications that require a high power drain. Very prone to 'Memory Effect'.
- Ni-MH: Nickel Metal Hydride. This battery type has virtually replaced the Ni-Cd batteries. This type offers higher capacities, around 30% more than a Ni-Cd cell of the same physical size. this type is also reported to suffer less from 'Memory Effect'.
- Battery Float Voltage: A unit for measuring electrical pressure. All batteries provide DC (Direct Current) electricity. It is important to ensure that the equipment you are powering is being provided with the correct volt or else damage may occur.
