Tom’s Hardware has been running some tests to challenge the common assumption that SSD hard drives use power more efficiently than magnetic plate drives. Their results were quite definitive: not only are they not as energy efficient, SSDs actually use more power than conventional hard drives.

What they found is that most plate drives are at peak consumption (up to 4W) when accessing files fragmented across the media, which causes the actuator to move back and forth across the media several times. However, this is almost never sustained for extended periods of time; the actuator usually doesn’t move much when reading unfragmented data, and most plate drives are also capable of going idle when they are not in use.
Buying a replacement laptop battery is a lot cheaper than getting a new computer. Some people are of the opinion that as soon as a laptop battery is giving some form of trouble, that the laptop should be immediately discarded. Well, with the present global financial crisis, spending money on a brand new laptop is not a smart thing to do, especially when you can purchase a replacement laptop battery instead – and besides, a brand new laptop is not cheap. BatteryHeads stock great replacement laptop batteries from top brands, which can be purchased at a very reasonable price.
Here are some tips that will guide you when shopping for a replacement laptop battery:
i. Find out if the battery will fit your laptop

It is important that you know whether the replacement battery you are purchasing for your laptop will fit snugly. It will be quite frustrating to discover that your new replacement battery does not fit after it has been delivered to you. It is no secret that replacement batteries look great in online catalogs, but you have to first of all make sure that you do not make the mistake of ordering the wrong laptop battery. You should know the make and the model number of your old laptop battery in order to avoid “fitting error”. BatteryHeads stock replacement laptop batteries from top brands such as: Sony Dell HP Compaq etc
ii. Make sure the voltage matches
The need to ensure that when shopping for a replacement laptop battery that you look out for matching voltages – this simply means that the battery’s voltage must match your laptop. If you for any reason feel that a matching voltage is a little bit pricey, then try buying a new laptop – hmm, didn’t think so.
Although, there are some computers that will permit a little discrepancy between voltages (say, about 1 volt), it is always better to find and purchase an exact match.
BatteryHeads has a replacement laptop that has your name written all over it, and it will not cost you an arm or leg.
iii. Figure out the type of rating that you want

Replacement laptop batteries have various types of ratings, you can tell the rating of a replacement laptop battery by simply looking at the actual rating which is indicated in milliamp-hour or watt hours. If you are wondering what the ratings mean, they indicate how much charge a battery can give and for how long the charge will last – the higher the rating on your replacement laptop battery, the more power the battery will have.
BatteryHeads offers customers different types of replacement laptop batteries that come with different ratings.
Most SSDs on the other hand, only have two states: on and off. This means that when they are on, they are always at peak energy consumption. Though this number hovers around 2W for most of the SSDs they tested, over prolonged periods this can mean a great deal more power consumption than is immediately apparent, which can have short and long term effects on the battery life of a laptop. See the Tom’s Hardware article for benchmarks of specific products and more in-depth data.
