Laptop Batteries FAQs
What is a battery?
A battery is a device that generates an electrical current by electrochemical reaction.
What is a battery pack?
A battery pack is an assortment of two or more battery cells, configured in a predefined order - a series, parallel or a mixture of both - to deliver the desired voltage, capacity, or power density.
What is Volt?
Volt (V), short for voltage, is a measure of electrical force or electrical pressure. The terminal voltage, measured in volts, of a battery is the electrical potential difference across its two terminals. Battery cells of different chemistries have different voltages. A nickel-based cell, like NiCd and NiMH, provides a nominal cell voltage of approximately 1.2 V and a Li-ion cell provides 3.6V/3.7V.
The voltage of two battery cells, of the same chemistry, is always the same. Their capacities may be different, but the voltage always remains the same. Higher terminal voltages are obtained by assembling two or more cells in a series, parallel or a mixture of both. For example, a 7.4V, Li-ion battery would be made up of 2 cells connected in a series.
2 cells x 3.7V Li-ion cell = 7.4V Li-ion battery
It is important that the voltage of a cell or a battery pack always matches the voltage requirement of the device in which it is used. If there is any mismatch of the two voltages, the device will not function. Excessive exposure to a different voltage may also damage the equipment. Equipment users should take special care that the batteries they are using matches the voltage requirement of their device.
What is milliampere-Hour (mAH)?
It is a unit of measurement of battery capacity, i.e. the amount of power packed into a battery. It is obtained by multiplying the current in miliamperes (mA) by the length of time that the current is flowing, abbreviated mAH. Higher "mAH" rating means higher battery capacity, which results in longer battery life between charges.
Â
What is the "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.
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.
What is self-discharge?
Self-discharge is the loss of charge in a battery when not in use. Unused batteries lose their charge over time. The loss of charge, or self-discharge, is the highest right after charge when the battery holds full capacity. Other factors like humidity and temperature of the storage place also contributes to the rate of self-discharge.
All battery chemistries self-discharge. Li-ion batteries have the lowest self-discharge rate at 5% to 10% per month as compared to NiCd, at 20% per month, and NiMH, at 30% per month, under identical conditions.
What is battery life?
It is the number of battery cycles, a full charge followed by a full discharge, a battery can offer before it needs to be replaced. Li-Ion batteries generally offer around 300 charge/discharge cycles.
