This is where a program like Battery Eater comes handy. It is a benchmarking tool for your laptop’s battery that tests your battery’s performance; estimates the minimum working time of a laptop, given all power saving options are turned off. The software is 100% free and the size of a download is less than 800 kb, so there’s no reason you shouldn’t try it ASAP.

Download and install the Battery Eater, and click on the “Begin test when disconnecting AC” option in the main window. Then, make sure the battery is fully charged and unplug the AC adapter to begin the test. The program will run CPU and GPU-intensive tasks until the battery of your laptop runs out which will give you an idea how many hours of operation you can expect from a laptop with a fully-charged battery. There are less intense tests as well, when the laptop is tested in “Reader mode” and “Idle mode” (these can be activated on the “Options” page). Upon completion, the program will generate a Discharge report and a log file that you can view and analyze.

In some cases the information you get may have an awakening effect on you, so much the discrepancy between the producer’s announced battery life and the real values will be. Hopefully, knowing the accurate information about your battery’s potential will motivate you to charge it more often and help prevent loss of any important data.

Now HP is given you the most effective solution of this problem. The battery is manufactured to give you enormous time to use laptop for your work. HP is offering its customers Sonata batteries, a like-new performance battery from Boston Power that would perform as well as it was brand new even after several hundred charges.

The battery is manufactured with a refined version of lithium-ion. These ultimate batteries may available for all customers from first section of 2009. The Sonata battery is recycling friendly and contains no heavy metals. HP will start making this option available to customers starting in the first quarter of 2009. No pricing information available at this time. I am waiting for these great batteries to move from problem of charging of laptop again and again. According to Boston Power, the first one thousand charges would give the laptop owners eighty-percent of its capacity before it starting to show tear and wear on the battery.

The device has a LED indicator that indicates the charging status of a laptop battery, a selection of adapters for a variety of most popular laptop brands and a connecting coaxial cable.

You can optionally add a back-up 12-volt lithium-ion battery to the charger, although it will definitely affect the overall weight of your hardware in a negative way. The device in folded form measures 170x170x45mm, and we doubt this charger will be compact and light enough to be carried around, but it might be your only choice if you are going to operate your laptop in unpopulated areas for a prolonged time. This is definitely a unique product for avid travelers and all the outdoor folks that can guarantee that they can use their laptops anywhere in the world.

The new technology allows to produce betavoltaic power cells that are small, thin, environment-friendly and non-thermal. Betavoltaics use radioisotopes as the energy source but, although they may sound nuclear, they are not. Neither do they produce any radioactive waste. The researches expect betavoltaic cells to appear on market in about 3 years.
