Robotics and Electronics Tutorial - 4 - Testing the Battery

[helipigg]

On my basic Craftsman digital multimeter there are 200mv/2v/20v/200v DC voltage measurements, and DC 1.5v/9v *battery* measurements. If I measure the voltage of a standard 1.5v AA battery using the 2v non-battery and the 1.5v battery measurements, I get a slightly different reading - probably 2-4% difference. Why is that?

So funny that he's saying to put the red on the + and the black on the -. You can switch those if you want, you'll just get a negative value.

r alkaline batteries u got....rechargeable?

[killer2611]

"black is negative" 

[daison5]

Thumbs up if you've licked the top of one of those batteries.

I got my probe out, I got my 9V battery out and I touched it on the tip. Now I have problems getting it up. What did I do wrong?

[Bladestorm687]

Please keep you videos going, i love them they are very detailed.

[360kal]

i have always thought that red was negative and black was positive

[007Neutrin0]

sorry, scrap my last comment, its a 9 V bat. not a 12 V.

[007Neutrin0]

wait, if you are using a 12 V bat, why would it say 9 V on your meter? makes no sense.

Thank you for the very clear-explained & visually-illustrated video!

[misty25girl]

thanks for your efforts .. and I hope you will post more videos :)

**Cough u....

btw, when u said, end of tutorial.. i thought it was over for good.... but a summary was after xD

[crazynoob11]

DUDE, you got alot of books on Scripting and ect. i saw them in the backround on the shelf. I can do for some of those @o@

[149328]

Tese are all very helpful. I'm new on the subject and there are a lot of sources out there that explain it in the most complicated, intimidating language possible. This video on the other hand, is very helpful and helps a lot.

[MrUnknown757]

Really gd vid learnt a lot thanks.

well done (Y).

[bodkin77]

why would you want to fill up the rubbish dumps with old alkaline batteries. You're robot will also have power for far longer at a time if you use other batteries. Use rechargable to avoid filling up the dumps and having to pissbolt down to the shops every 5 minutes

[ecn1984]

I like to use old batteries, in series, for testing purposes of my circuits.

[JunThailand]

I love the video because I am a newby....

[xpsniperguy]

hahah he's got a rubix cube in the back round XD

There's no cost comparison between rechargeable and non-rechargeable batteries. Rechargeables can be recharged hundreds of times. Unless necessary non-rechargeables should never be used.

i couldn't agree more.

2. yeaaaaaaaa lol great tut
