There are several important aspects to think about when you are buying a laptop computer. One of these aspects is the laptop battery life. Because laptop computers are so mobile, you will not always have electrical power. I used mine every night with my with wife as she was driving to law school. I can tell you that there is nothing more annoying than working on a project and having your laptop tell you that you have five minutes of battery power left. I have found that lithium mines ontario batteries work better than the Nickel Cadmium batteries. I have also found that you can actually 'train' your batter to have a good memory effect.
These can be found at your local PC repairs store in many cases. If they do not have them in stock, they may be able to find them for you. The best news of all is that they will likely be far cheaper than what you would have to pay with the manufacturer. For the most part, you will likely purchase a Lithium mines Ontario Ion battery for your laptop. This is extremely popular and the type used by most manufacturers to date. All you need to do is contact your local PC repairs shop and ask them about any laptop batteries they might carry or if they can get them.
LG cellphone batteries may contain the same amount of lithium and last the same amount of minutes but the built of the batteries also depend on the cellphone models that they go well with. If you are looking for information on LG cellphone batteries, then you should also read up on the standby powering issues. Now this is possible by checking as many websites as you can. Information is everywhere so you wouldn't be grabbing straws. But because the information on LG cellphone batteries can be found right and left, you shouldn't be overwhelmed.
When it's time to buy a new lithium ion battery, be sure you're buying one that's new (as in recently produced). Just like fruit has a shelf-life, so do batteries and just like you want to buy fresh produce, you also want to invest in "fresh" Lithium battery stocks ion cells. Check the date-code on the battery or packaging to ensure you're not buying a pack that's been degrading for a year on some shelf.
Memory effect will reduce the life of a battery. Modern Lithium-ion batteries do not suffer from memory effect, although it does occur in Nickel-Metal Hydride (NiMH) units when charged from levels other than 0% of battery capacity. If the (NiMH) unit was fully charged when initially at say 20% capacity, the resulting available capacity would only be 80% of the factory original. Of course every time you charged the battery, the total available capacity would reduce and eventually your mobile phone would prove to be increasingly useless. Nearly all new electronic devices are now powered by Lithium batteries. You should always condition your (NiMH) battery from new.
The odds that you will using the Lithium-Ion batteries are 99% ( that's if you are using the new breeds of laptops :) ). Just check the abbreviation that says LION or Li-Ion on your laptop battery label. There are still a few laptops that are using Ni-MH batteries these days and you might want to check with the manufacturer whether you can do an upgrade from Ni-MH to Li-Ion. Using unapproved batteries could led to dire consequences .... so do be very careful on this. If you have a higher budget you might want to check out SMART batteries. It has a power management circuitry and it will indicate to the user what is the current condition of the battery.
