The new MacBook Pros now all come with sealed batteries. This was just once the territory of the mighty 17 inch model. Not anymore. The recent refresh brought that technology to its smaller siblings, the 15 inch and the recent addition to the MacBook Pro line-up the 13 inch.

According to Walt Mossberg who had the chance to test both the 13 and 15 inch MacBook Pro and put it through the paces of his own battery test, both laptops performed well. The 13 inch lasted a slighty below the 5 hour mark while the 15 inch was 21 minutes above the 5 hour marker. This says well considering no power saving feature was turned on and the screen brightness was cranked up. In normal usage, expect battery life to be even slightly higher.

I for one was at first skeptical of the notion that I can’t replace the battery of my laptop. However looking back, ever since I’ve owned a laptop, I’ve never bought a spare battery. Hmmm… I guess I just like the thought that I could replace it if I wanted to. Mossberg cites in his article that only less than 5% of consumers actually buy spare batteries. This figure was from NPD, a research firm. I would believe that this figure is close to the truth.

I guess we just need to let go of our need to control things and trust that technology works. Apple was able to increase battery size and life in its MacBook Pro line of computers without adding weight or heft. I guess its a decent trade-off to the fact that you can’t replace it yourself. Apple also claims that their batteries will last up to 5 years. So by the time it’s time to change batteries it’s also time to change computers.

So we’ll see in the days to come if indeed sealed batteries are the way to go.

I recently got a new battery for my laptop. I’ve been working without a useful battery for quite some time now. I couldn’t even get all the way through an initial startup without getting a critical battery alert if I wasn’t plugged in. Now I’m happy to say I’ve got a new battery and can truly work wirelessly again.

After checking a variety of websites I ended up at DuracellDirect.com and purchased a replacement battery for my laptop. After receiving my battery, on the paper that was included with the packaging it gave me some tips on prolonging the life of my new battery. Among those tips were to not charge it unnecessarily. It recommended that when computing on direct power by being plugged into the wall, to remove the battery from the laptop.

I began to think that would be a great idea. That was quickly followed by asking why there wasn’t a software switch within my operating system to disconnect my battery from being charged when the computer was plugged-in. After typing that sentence I thought to myself why this couldn’t be automatic when the computer knows it’s plugged-in.

Does anybody know if this is an option at some point on some system in the future? If it really helps batteries, why wouldn’t that be a standard feature these days?
