Why your computer really needs a battery backup device
Battery backup devices have been around for decades now, but relatively few computer owners use them. And based upon my experience, that is a mistake.
What are battery backups (and why do I need one)?
If you're unfamiliar with how it works, a battery backup unit basically sits idly by monitoring the power line for voltage drops and power outages.
When an issue with the power line occurs, the power source to the computer is switched virtually instantaneously from line power (electrical outlet) to the unit's internal battery. This prevents the computer from losing power.
Why is preventing your computer from losing power important? Well, there are several reasons:
1 - A sudden power loss can corrupt your Windows installation, resulting in the computer refusing to boot up again without a visit to the repair shop.
2 - Brownouts and power losses can weaken the internal components of your computer or damage them outright, again resulting in a trip to the repair shop.
3 - If your computer shuts down unexpectedly while you're using it you'll lose any unsaved work, which can be a huge loss if you've been working on an important project for an hour or two.
As you can see, running your computer on wall power alone is extremely risky just because of the problems associated with power drops and outages. But there is even more to it than that...
Power surges and lightning strikes can damage, or completely destroy your expensive computer equipment. And while a standard surge protector certainly helps, the surge suppression built into most battery backup units is generally a bit more effective at reducing or eliminating those dangerous surges.
What's more, the better (i.e. more expensive) battery backup units also contain line conditioning circuitry which ensures a steady supply of "clean" voltage at a rock solid 60 HZ.
Choosing a battery backup unit
Battery backups are rated in both wattage and estimated run time for different types of PCs (laptop or desktop) .
Note: Battery backup devices also have a "VA" rating, but I recommend choosing one based on the wattage rating since computers and related gadgets are typically rated in watts.
Since the wattage rating of most battery backup units is around 60% of the VA rating, if you select a battery backup based upon the wattage you won't really need to be concerned about the VA rating.
In general, the higher the wattage it can supply to the computer and the longer it will keep it powered up the better, therefore the wattage is the most important attribute to consider.
Personally, I won't purchase a battery backup that supplies less than 300 Watts because personal experience has shown that anything less is inadequate for powering today's PCs and monitors. The one that powers my "work" desktop system is rated at 900 watts.
Depending on your particular situation, you might even consider using multiple battery backup systems. For example, I use the aforementioned 900 Watt unit to power my "work" desktop PC and monitor and a separate 350 Watt unit to power my cable modem, router and wireless landline telephone.
That way when the power goes out I have at least a couple of hours during which my Internet connection and landline phone will continue to work. With any luck the power will come back on before that which means there will be no service outage.
How much does a quality battery backup unit cost?
The most popular consumer grade battery backup systems are made by APC and CyberPower.
Prices start at around $50 or so, but I recommend that you opt for at least a 450 Watt unit even though it typically cost a few dollars more.
Of course models with line conditioning built in cost more still, but I believe the extra investment is definitely worth it.
Conclusion
In my opinion it makes sense to spend just a few dollars more than you would pay for a quality surge suppressor in order to protect your expensive computer equipment from damaging power surges, brownouts and power interruptions with a quality battery backup device.
After all, a few extra dollars spent now will save a lot more of them later on, not to mention the aggravation you'll feel if you lose the fruits of your hard labor.
