Will a higher capacity (mAh) battery ruin my laptop?

Rechargeable batteries have a lower capacity than disposable alkaline.

It is quite common that some people think that a single use battery lasts longer than a rechargeable battery. The logical error here is "give and take" alkaline battery provides a charge long, while the rechargeable battery offers many short positions. This is false. Rechargeable batteries are made using the chemistry of nickel-metal hydride is greater than the alkaline manganese http://dell6000.blog.com/ zinc and use of chemicals oxide. A charge cycle of a rechargeable battery will last 3-4 times longer than a charging cycle of disposable alkaline battery. The real "give and take" here is that the rechargeable batteries cost much more than disposable alkaline, well, you need a charger too.

Verdict: False


Misleading battery terms: Batteries Super last duty instead of a battery of non-super destination.

Do you recognize any of the following steps in the packaging of the batteries? high strength, high strength Super, Ultra capacity, rapid charger, long life, the maximum load, etc.

Since there is no industry standard capacity of a battery from now, many companies use these words to market their batteries. The correct way to find the power of a rating to see the chemistry of the battery and made. To clarify things, a "Super Mega Heavy Duty" alkaline battery would have no chance against a standard lithium battery.

Verdict: False


Put the batteries in the freezer prolongs its life.

Keep Alkaline batteries stored at room temperature, "only gives them a self-discharge rate of 2% per year. Since the type of car is so low, it is not really worth going through the hassle of putting them in the freezer and take space that could be used for ice cream. Although the myth is technically true, it is likely that you put the batteries for use in less than a year.

But, if the batteries are stored at higher temperatures around 85 degrees Fahrenheit, the actual discharge rises to 5% and the increase of 100 degrees at 25%. So basically, do not worry about the batteries lose their charge unless the weather is very hot.

Verdict: (technically) True


It is best to recharge batteries slowly.

There are some people who believe that chargers overnight are best for rapid battery chargers because the slow transfer of energy does not diminish its capacity. In fact, there fastloaders adversely affect battery capacity worse than other chargers out there. The real cause of the loss of capacity is overloaded. When a battery continues to charge after reaching maximum voltage, the capacity will slowly decrease. Make sure the charger is a "smart" charger automatically shuts off when the batteries are fully charged.

Verdict: False


You must use a rechargeable battery until you are dead.

This is true for Ni-Cad and Ni-MH batteries. If not fully used their energy and the defendants will begin to develop a "memory." Decreases the total memory capacity of a battery. The more memory the more it loses develops a battery capacity. This is not true for lithium ion cells however. the lithium ion cells are not affected by the memory effect and can be recharged at any time.

Verdict: True to Ni-Cad and Ni-MH, Li-Ion False.


Storing a lead acid battery on the cement floor slowly download.

The storage, charging batteries or operate in the concrete is perfectly fine. The most important things to avoid:
1.Freezing. Avoid places where it is expected that the freezing temperature. Keep the battery in a high state of charge also prevent freezing. Freezing results in irreparable damage to battery plates and containers. [The freeze may occur between -19 degrees Fahrenheit (40% load) and -98 degrees (fully charged)]
2.Heat. Avoid direct exposure to heat sources such as radiators or heaters. Temperatures above 80 degrees accelerate the characteristics of the battery self-discharge.
3.Step storage step of the procedure: 1. Fully charge the battery before storing. 2. Store in a cool, dry place, laptop battery dell protected from the weather. 3. During storage, monitor the specific gravity (flooded) or voltage. Storage batteries should be given a quick charge when they show a rate of 70% or less. Fully charge the battery before restarting.

The best place to keep an SLA battery is in a cool environment with a battery supply. offers from the battery to keep the battery at a voltage of proper storage so that it retains the capacity. Some of them also improve their performance.

Verdict: False


Increased capacity (mAh) battery ruin my laptop?

Increased capacity (mAh) will not ruin your laptop. Extended batteries are those that have more capacity (mAh), or amps, to improve the device for an extended period of time. If your laptop has been driven by a lower capacity (mAh) battery, switching to a long lasting battery with more capacity (mAh) will not damage your laptop. The devices can only be affected if the stresses do not coincide.
