Uniwill 755CI0 Laptop Battery

Volts: 14.8v

Volts

Close

Voltage is different for ac adapters and batteries.
For ac adapters, there is a 1v tolerance in relation to what you actually need. For instance, an ac adapter shown with a volts rating of 19v, will be suitable for use with a laptop requiring 18v, 18.5v, 19v, 19.5v or 20v, but not 17.5v or 20.5v.

For laptop batteries, it is recommended that you use the same voltage as what your laptop needs, anything higher than the rating on your existing battery can potentially harm your machine, however there are exceptions.
10.8v & 11.1v batteries are fine to interchange.
Some 11.1v batteries are interchangable with 14.8v batteries but this depends on the mAh or WHr rating on the battery also.

If in doubt, call us so we can check and be confident that we supply the correct battery. Do not take the risk of choosing a product which has different specifications to your existing battery where voltage is concerned as you may not only damage your laptop, but you may also void your warranty on your laptop and also void the warranty from us.

mAh: 4400mAh

Battery Capacity

Close

Battery capacities are measured in mAh (Milliamp Hours) or WHr (Watt Hours).

This figure relates to how much power the battery is able to hold. Batteries with a higher mAh capacity will theoretically last longer without requiring a recharge, allowing you to use your laptop for longer.

It's impossible to tell from the mAh or WHr rating exactly how long a battery will last as it depends on how much of a drain your laptop places on the battery and each laptop is different. Screen brightness and Hard Disk activity are examples of things that will effect the drain.

To try and understand how long our battery will last compared to your original battery, it is really quite simple. If your original battery has the same capacity as ours and it lasted for 3 hours when it was new, our battery will also last for 3 hours.
If your original battery has a lower capacity than ours, our battery will last for longer.

Laptop batteries have approximately 300-500 charge cycles (charge & discharge), so the more you use it, the quicker it will need replacing.

The number of cells inside the battery are an indication of the amount of power it can hold.

Inside your laptop battery are a number of individual battery cells. These cells can vary dramatically in quality and capacity.
The number of cells inside the battery are an indication of the amount of power it can hold. and whilst different manufacturer's batteries may all look similar, the internal battery cells are very different.
All batteries supplied by laptopsandspares.com are manufactured to the highest quality using components from top brands such as Panasonic, Samsung, LG etc.

Cell type and cell quality should be considered when purchasing.

You will see many websites offering cheap batteries, but they are almost always of a very low quality and simply do not last. All of the batteries sold by laptopsandspares.com are manufactured using high quality, branded cells from manufacturers such as Samsung, Panasonic and LG and all come with a warranty as stated on the product page.

Type
Most laptop batteries today are Li-Ion (Lithium Ion). Li-Ion batteries will usually provide you with a longer charge and have a better weight to power ratio than older Ni-MH (Nickel-Metal Hydride) batteries which you rarely see in laptops now.

If your laptop still has a NiMH battery, upgrading will give you a lighter laptop and a longer life battery.

Quality
The quality of battery cells varies enormously.
