[OT] Battery Backup for Laptop

If the laptop is that old, you might first try a new battery. As batteries age they hold less of a charge.
Someplace like Batteries Plus, might have a battery. You can also get different batteries that hold charges for a longer periods of time.

Subject: [Vantage] [OT] Battery Backup for Laptop



I've setup an old laptop on roving inspection cart. The built-in battery lasts maybe 90 minutes. We would like to get at least six hours. Rather than install a car battery and an inverter (and trickle charge overnight) I figured all this is built in to most UPS battery systems. But none of the run time calculators have an option for laptops.

Any idea what size (watt and volt amps) would be needed? The transformer pack says it draws 1.7A so about 204VA. But what determines run time? Watts in relation to VA?

Another thought is that UPS units are designed for sporadic use and not a daily "power outage" when the cart goes roving. I'm wondering if this will reduce the battery life.

Any thoughts, opinions or musing would be much appreciated. I just don't want to over buy on a UPS otherwise the car battery route could be less expensive.

Thanks,

While I don't know any of those specs or how to figure out how long it would
last.

One warning I have would be to make sure you can disable the alarm on the
UPS so you don't have to deal with the constant beeping while it isn't
plugged in.

If you go the battery and inverter route, use a deep cycle battery instead of a car battery. Car batteries are intended to provide a high dose of power for a short period of time. Deep cycle batteries are intended to provide a moderate amount of power over a long period of time. Deep cycle batteries are more expensive than car batteries, but will last longer if used for the purpose you describe. Deep cycle batteries are available at boat supply stores, and stores that cater to people who are setting up to live off the grid. Be careful when working with any electricity. Even the 13.2 volts from a battery can give you a big jolt if the amperage is high enough (still safer than working with 110 volts or more, though).

Great thought. If I do got that route I will also look for a 12V car adapter type power pack and skip the inverter if possible. But it's an old Acer laptop and finding the 12V DC input power might be difficult now, and a small inverter cheaper.

As for Ned's thought on UPS beeping...in our plant nobody will hear 45dba. But we had given though to clipping the sound maker.

I think I am going to start with a 800VA 540W APC unit and if it does not work out I can always use it on a desktop PC somewhere.

Thanks,
-Todd C.

And having experience living off the grid on a boat with an inverter, use (2) 6 volt golf cart batteries (connected in series) instead of a 12v deep cycle. Longer charge life and longer battery life. And you'll need a way to charge the batteries, some inverters are dual inverter and charger. To increase battery life further, get a 'smart' three step charger. Another option is to use a car charger and eliminate the inverter. Probably too much information....
