I apologize if this post runs long. I feel these points must be made for you and for those pondering if they should move to internal battery notebooks.
but personally, would you consider getting a laptop w/ a sealed battery? I dunno if its just me but I'm kinda getting paranoid getting one.
My first impression of built-in batteries were obvious: I knew the dangers of lithium ion technology and the implications of a failed battery to any consumer electronic product. I resented the fact that the move to internal battery systems were due to the popularity of the unibody MacBooks, thanks to the majority of their less informed connoisseurs.
At least for Apple, they charged at premiums which allowed them to provide a sufficient amount of quality with their battery systems. You knew that at some point the money you spent went to the manufacturing quality of the battery, minimizing the risk of failure due to defects.
However, we also do know that even with stringent quality protocols, there are loopholes. Apple was once the subject of scrutiny due to the case of the exploding battery and the phenomenon even spread to their premium notebooks.
At the advent of the Ultrabook initiative back in 2011, I was introduced to the appeal that the popular movement reserved for itself, thanks to the Acer Iconia W700. Some time after, despite my apprehensions, I bought for myself a Z400 which would eventually be my firsthand experience with internal battery systems.
Internal battery systems, while technically no different from the removable battery systems (besides the obvious facets), do have their quirks:
- Internal batteries drain continuously even when shut off - up to the point that it dies in about a week of non-use.
- The non-encased internal batteries also radiate (or conduct, depending how close proximity it is to the rest of the system) heat more openly to the system.
- They do not possess any management circuit of their own; they rely on the power management circuit of the notebook thereby introducing power management transparency but also vulnerability if the power management circuit itself fails.
- They are removable, however; many manufacturers will void your warranty for doing so, even if it is advised to remove the battery if the notebook will not be used for more than three days.
For a while now, I've had less reservations against the idea, only to certain points. But reservations do remain, especially against use of polymer batteries when you're unable to visually inspect them for wear easily.
The following are the notebooks I own that use internal battery systems:
- ASUS X550LB
- ASUS T100TA
- ASUS G46VW
- Lenovo Z400
- MSI S20 v1
I've had no issues with any of them, although I have removed the batteries for the G46VW and the Z400 (voiding their warranties, of course) for long term storage. Every time I return to the Philippines, I do install the batteries again for charging and use. Like the removable batteries, the internal ones hold sufficient charge at about half their capacity for a good 6 to 8 months of storage.
The reasons to use of internal battery systems is diverse; but a main reason to use them is to reduce the thickness of the notebook. Encased batteries cost more, since some would require their own management circuits and plastic chassis. And with internal battery systems, there's little need to manufacture a surplus of spare batteries for replacement. Customers would need to send their units in for repacking.
Sadly, I cannot recommend trying such a notebook if it is your first. I would only advise such notebooks to veteran users who've had experience in maintaining their own notebooks. Experience with a removable battery will prompt you to reconsider your computing and maintenance habits when it comes to a new notebook sporting a battery you can't see or remove.
I'm just having a hard time looking for comparable laptop specs wise w/in the budget.
I completely understand your plight. Alas, it is not up to me to decide if the value of the notebook outweighs your obvious concerns.
