I have seen different battery cell types like 6, 9, and in some cases 12 cells, exactly what are they?

This number indicates the volume of individual cells utilized to make up a laptop battery. The more cells, the larger the capacity with the battery. Generally, the car battery with the lowest volume of cells will be the standard battery that was included with your laptop. The 9-cell or 12-cell batteries would be the extended, higher capacity batteries that may provide you considerably longer run-time for a passing fancy charge.

Before choosing a battery with additional cells, you’ll want to weigh up the advantages vs the other size and weight, notably if you carry your laptop around along all day.

Is the grade in the battery cells important?

In general, a laptop battery will supply between 400-800 life cycles determined by usage and battery quality. Lower quality or poorly manufactured batteries can provide fewer cycles, and also a shorter overall lifespan.

Highest Quality Batteries (Grade A Cells) - 12-1 . 5 years
Medium Quality Batteries (Grade B Cells) - 10-15 months
Low Quality Batteries (Grade C Cells) - 5-10 months

How long will the brand new battery power my laptop?

Actual battery run-time is dependent upon the power demands created by the equipment for example the applications you might be running and also your laptop settings. Our replacement batteries might last the same or over the original battery which came with all the laptop if this was fresh (at a similar capacity). Generally, an ordinary 4400 mAh last between 45-90 minutes. You can calculate just how long a higher capacity battery might last based on the mAh difference. A 7200 mAh battery provides you with 64% more run-time, along with a 10400 mAh gives you 136% more run-time compared to 4400 mAh for a passing fancy charge.

How long does a laptop battery last? When should I consider replacing mine?

All rechargeable batteries tire out with some time and usage. As some time and cumulative use increase, the performance will degrade. For the typical user, noticeable lowering of run time generally will probably be observed after 18 to two or three years. For an electrical user, decline in run time generally could possibly be experienced previous to 18 months. We recommend getting a new laptop battery if the run time isn’t going to meet your needs.

What are watt-hours, volts and milliamp-hours?

Every battery has three ratings that happen to be watt hours, volts and milliamp-hours.

Watt Hours (wHr) is often a unit of one’s equal to the project done by one watt acting first hour and similar to 3,600 joules. The wHr is really a calculation of voltage and mAh.

Milliamperes (mAh) is often a unit of measure electricity over time. It represents the total amount of your energy store inside your battery. The mAh rating can be another measure of the quantity of hours battery power may last. The higher an assortment’s amp hour rating is, the longer the car battery’s run-time will likely be. It is not uncommon for a lot of of our batteries to obtain higher or lower amp ratings. This will not cause any incompatibilities.

Voltage (V) would be the amount of electricity that’s delivered to your pc. The amount of your energy from your wall outlet is more than what your laptop has to operate. Therefore an electricity adapter includes a box like bar that could decrease the energy reducing the voltage rating. Each computer manufacturer designs their computers with the appropriate voltage requirement. Your battery power will then be engineered to suit the voltage with the power AC adapter. Laptop battery packs are made of several battery cells which are wired together in series. While the voltage in the Hi-Capacity battery most likely are not identical to the main battery, the voltages has to be within a reasonable range. Any replacement laptop battery ought to always be within +/- 1V. Anything above that range might result in incompatibilities.
