Re: laptop batteries....

Using the laptop only with AC is generally fine, but you may want to get a UPS (some people think that this is silly, but a new OEM lithium battery costs $200+, and a laptop is 80% to 90% less expensive). In fact, this week, some of the major electronics chains have the APC 350va ups on sale for $19.95 after rebates. The considerations and arguments for getting one vs. not getting one are the same as for a desktop PC. Personally, I have come to the position of recommending that ALL PCs be powered from a UPS. For a laptop, the battery certainly is a UPS, it's just a very expensive $200+ UPS when a $20 UPS would work as well (better in fact, as the run time is a lot longer if nothing else is plugged into the UPS).

Thank you everyone for your advise. The laptop I will buy has a Lithium
battery. I have learnt the following are more efficient methods to prolong
battery duration:
-I will try and power my laptop the majority of the time by AC connection
(with the battery removed obviously). I will store my battery at above 50%
when not in use.
-I will not discharge my battery below 20%.
-I will not overcharge my battery
-I will avoid using the battery in intense heat

BTW, Can it harm a laptop to never use a battery and use it as a desktop PC
with an AC connection?

Thanks again,
Nick.

Hi People,

I am looking to buy a laptop but I really hate the fact we are in the 21st
century and laptop batteries last for about a max of three hours and have


a

lifespan of 3 years. I would like to know what people think about 

'tweaking'

your laptop to extend its operating time and its lifespan. I have listed
below a few points below that I heard would help optimise the battery's
performance.

- Disable background programs which use up power from the CPU and hard
drive.
- Disable network connections unless it's in use.
- Choose a laptop which uses a Centrino/Pentium M processor which alters
processor speed rather than a standard P4
- Reduce the brightness of the display. Turn off when not in use.
- Add more RAM so it reduces the usage of hard drive.

Am I right in thinking this will help prolong its duration? Does anyone 

have

any other pointers?

Also, can a someone confirm whether the statements below are true please:
"it's best to store batteries at about 40% charge"
"Never store them for long periods completely discharged or they might not
recharge at all"
"It's better not to fully discharge lithium-ion batteries " - note: I


heard

you should Fully drain and fully recharged your battery pack every few
months.

Thanks in advance,
Nick.
