using truck battery on Toshiba notebook?

Don't do it. It will risk creating a fire. NEver mix batteries with laptops.

in the beginning, how previous is the battery? despite if that's greater effective than approximately 4 years previous, that's in basic terms wiped out and can get replaced. If that's greater recent, how do the terminals look? in the event that they are severly corroded, you'll be able to desire to might desire to eliminate and sparkling them (and coat them with a layer of dielectric grease to sidestep this interior the destiny). examine to work out that the cables themselves are not corroded. If the battery isn't maintenance loose, heavily open the caps and examine the water/electrolyte point. interior each and every hollow, the point might desire to be as much as the backside of the plastice "cup" that runs some million/2 an inch interior. despite if that's low, fill it with sparkling (ideally distilled...yet who has that laying around?) water, being constructive to no longer permit any airborne dirt and dust or crud to fall in and contaminate it. once you have accomplished all that, the battery will nonetheless likely desire a charge/leap, yet this time it could truly take the charge. in case you have a battery charger, use that for some hours and notice what happens. A voltmeter will honestly be powerful. a completely charged 12v battery might desire to truly study from 12.5 to 13 volts. With the engine working, the alternator might desire to save the voltage close to 14 volts, reckoning on the burden on it. If the voltage would not strengthen in any respect whilst the engine is working, the concern is interior the autos charging equipment (alternator, voltage regulator, wires, fuses, etc.) ideally, till between the straightforward ideas (water point, terminals, cables, etc.) artwork, the two the battery and the alternator might desire to be load examined. some autoparts shops will load try the battery for loose. i offered an low-cost ($30or so) load tester myself some years in the past, and use it each and every of the time. It provides a greater significant degree of the battery's difficulty than an trouble-free voltmeter.

Earlier poster is right, get a car adapter matched to your Toshiba. That can be pricey. So go to Radio Shack with the AC adapter you have and they can get you one of the DC adapter kits fixed up for about $30. You MUST get the voltages right, you'll find that info on the label of the AC adapter; then get an add-on 12v recepticle (female). Connect the wires from that to the + and - battery terminals. Dirty Harry says you have a 50-50 chance to get it hooked up right so you've gotta ask yourself "Do I fell lucky?", well do ya - punk? :-)

You'll have to get some type of enclosure for the battery, you don't want the terminals to touch any metal. Or duct tape some pieces of cardboard together so it will slide over the battery and just leave the handle uncovered. No strap? Old laptop bag straps can be fashioned into a sling. Do you have a hernia? Well, you will.

Too much amperage, will fry your computer

Buy a car adapter for your Toshiba, wire a data port or cigarette lighter receptacle to it and away you go.

I'm just dying to watch you go through security at the airport with the lash-up in laptop bag (LOL).

Good Luck

do it

the amperage is all wrong it would fry the laptop
