has this ever happened to you? you need batteries but you are always one short. well no more! this instructable shows you how to use one less battery and best of all.. its so easy and basic it hardly takes a minute. please note that this will decrease the life of the batteries as they are doing more work than usual. also this does not work if the batteries line up end on end.

Step 1: What You will need.

 -electronic device.
 -battery (please note that this hack works best if you use more than half the batteries required for the device)
-click pen
i will need to try this but will the remote (in this case) be powered by 1.5V, because 2 battery will make 3V
That's good.
That's nice!
I just tried it. Cool. I'm guessing that you might loose some range. But if range isn't a problem then cool go for it....
this is a great idea, and the spring probably will not make much resistance
One thing. Many devices require more than 1,5 volts. For example normal LED - witch can be found in many many devices- needs 'bout three volts. So 1,5 wont be enough. And looks like that remote used in this instructable connects the batteries in series so it makes it three volts, but maybe it then uses uses only 1,5 volts.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; One thing was pretty long :-D<br />
Are you sure this works?<br /> <br /> This is halving the voltage...<br />
I did this with my gameboy color back in the day... It works, but you kill batteries quick.<br /> <br /> It has potential to damage electronics. But that's pretty unlikely.
Interesting!&nbsp; Will have to remember this!<br />
ooh good
Use rechargeable batteries, and even then some devices don't work well, or long.&nbsp; Not sure what devices would benefit from such a hack, maybe if you just can't find enough batteries, and don't want to make a trip to the store any time soon.&nbsp; With fewer batteries, you tend to run them down much quicker. &nbsp;<br /> <br /> Guess this sort of make sense, if you have no other options, but really shouldn't be a substitute, since you aren't going to save money on batteries.<br />
I&nbsp;don't know if he changed the intro after you posted this, so I&nbsp;won't go at you for not reading the first line, but the idea is when you NEED&nbsp;batteries for something, but then turn up one short.<br />

It worked on a tv-remote I had, they don't require much, but anything else I&nbsp;don't know.<br /> Funny, I always have a spare battery lying around. Most of my kids toys need 3 AA batteries, but of course they're sold 4 in a pack ;-)<br />
