Laptop Batteries Info | Notebook Battery & Laptop Battery FAQs
At Battery Giant, we want our customers to be happy with their laptop battery purchase. We achieve this by providing our customers with the information they need regarding laptop batteries. Below are basic laptop battery FAQs to help answer any of your general questions.
Q: How can I maximize the performance of a laptop battery?
A: There are many ways to help maximize laptop battery performance:
- Keep your laptop battery and the contact terminals as clean as possible. The contacts inside of batteries for laptop computers can be cleaned with a swab and most types of cleaning solutions.
- Avoid exposing laptop batteries to extremely hot or cold temperatures.
- Keep the laptop computer battery active. If possible, avoid letting batteries for laptop computers sit dormant for long periods of time.
- If a laptop battery is expected to be idle for a long period of time, properly store the laptop battery in a cool, dry location.
Q: What is the safest and most responsible method of laptop battery disposal?
A: We advise disposing of old laptop batteries to an organization that is established to handle and properly dispose of batteries in an environmentally friendly manner. Such disposal locations exist in most areas throughout the U.S. Additionally, many retail stores now offer laptop battery disposal services. Battery Giant promotes proper disposal of laptop batteries and can offer further insight regarding safe battery disposal and how to go about recycling a laptop battery.
Q: How long do replacement laptop batteries typically last? What is the lifespan of a battery for laptops?
A: The life of replacement laptop batteries is determined by the number of charge and discharge cycles the laptop battery can support. Depending on the type of laptop computer battery and how often it is used, many batteries for laptops can last up to several years. As a laptop battery nears the end of its life, the "stand-by" periods will be noticeably shorter.
Q: What if the laptop battery gets hot while being charged?
A: It is typical for some laptop batteries to warm a little while being charged. However batteries for laptop computers should not get hot. If a laptop battery gets really hot while charging, it may be a sign that the laptop battery is possibly defective. In this case, it is recommended to stop charging the laptop battery and to consider disposal.
Q: Can laptop batteries experience overcharging?
A: It is unusual for laptop batteries to experience overcharging. The advancements in batteries for laptops make it very difficult to overcharge the battery for a laptop. Protection from laptop battery overcharging is built into the power functions of most laptop battery charger systems. It is highly unlikely that leaving a laptop battery in a suitable charger will cause damage. A simple precaution to avoid laptop battery overcharging is to not leave laptop batteries on a charger for more than 12 hours.
Q: What should I consider when purchasing a replacement laptop computer battery?
A: There are some important factors to consider when buying a replacement laptop computer battery. While shopping for replacement laptop batteries, it is critical to consider size/application and warranty. Although it is recommended to consult the manufacturer's recommended guidelines in attaining the correct replacement laptop battery, below are some general factors to consider while selecting a replacement laptop battery.
First, you have to make sure the replacement laptop battery will fit appropriately. Check the physical dimensions and required voltage of the new laptop computer battery with that of your original laptop battery. Also, consider the warranty period of the laptop battery. We recommend choosing batteries for laptops with a warranty period that best fits your needs. In most cases, your laptop computer manufacturer will provide the exact replacement laptop battery specifications you need.
Q: How does a laptop battery work?
A: A laptop battery works similar to other common batteries. Batteries for laptop computers store energy in a chemical form that can be released on demand as electricity. Most laptop computer battery cells consists of positive plates, negative plates and an electrolyte solution. Laptop batteries produce electricity because of the chemical reaction between these elements.
Q: What causes laptop computer batteries to fail?
A: There are several factors that contribute to the failure of laptop computer batteries. Excessive heat can dry out the laptop battery cell. This is among the primary reasons for the failure of laptop batteries. Extreme cold weather can sometimes put a heavier drain on laptop batteries. This also is a common contributor to laptop battery failure. Other possible factors that can cause replacement laptop batteries to fail include corroded terminals or electrical shorts within the laptop battery cell. These are just some of the common causes of laptop battery failure. In general, laptop batteries can vary in composition, which can influence how laptop batteries depreciate.

The Memory Effect And Laptop Batteries
Many laptop batteries experience the "memory effect". You can overcome memory effect problems by recognizing certain laptop batteries and which ones are more vulnerable. The "memory effect" can be best presented by distinguishing lithium-ion laptop batteries (Li-ion laptop batteries) apart from nickel-cadmium laptop batteries (NiCd laptop batteries) as well as nickel metal hydride laptop batteries (NiMH laptop batteries).
The memory effect is common in nickel-cadmium laptop batteries (NiCd laptop batteries). The downside of the memory effect in NiCd laptop batteries is the battery's inability to fully recharge. In other words, nickel-cadmium laptop batteries (NiCd laptop batteries) are unable reach their full charge capacity after a period time.
How do NiCd laptop batteries experience the memory effect?
Nickel-cadmium laptop batteries (NiCd laptop batteries) are unable to reach a full charge capacity when the laptop computer battery experienced "voltage depression". Voltage depression is a common issue with both NiCd laptop batteries and NiMH laptop batteries. This occurs as the voltage in the laptop battery drops unusually fast as the laptop battery experiences discharge. The voltage drop in NiCd laptop batteries as well as some NiMH laptop batteries can occur from persistent overcharging and aging. Laptop batteries cannot counteract aging. The older a laptop battery gets, inevitably, the less capacity the laptop battery will have over time.
Fully discharging nickel-cadmium laptop batteries (NiCd laptop batteries) helps to counteract voltage depression. However, fully discharging whole laptop batteries may result in the "stronger" laptop battery cells reversing the charge to "weaker" laptop battery cells. This can be highly aversive for the weaker laptop battery cells, and can potentially drain a laptop battery abnormally fast.
Avoiding The Laptop Battery Memory Effect
There some precautions users can take in avoiding the memory effect with laptop batteries. Consider the following points to avoid the laptop battery memory effect.
- Find out which type of laptop battery is in your computer.
- Some laptops still use nickel metal hydride laptop batteries (NiMH laptop batteries). See if you can acquire a laptop battery upgrade to the lithium-ion laptop battery (Li-ion laptop battery).
- To help prolong the life of nickel metal hydride laptop batteries (NiMH laptop batteries), fully drain or "use up" the NiMH laptop battery. After the laptop battery drains and fully recharges, fully drain the laptop battery one last time, followed by a full recharge. Sometimes bringing the laptop battery to a full drain and then back to full charge capacity can help prolong the life of the laptop battery.
