https://www.indiegogo.com/projects/batteriser-extend-battery-life-by-up-to-8x#/story

T
hese purport to extend the life of a battery by 8x, but it seems too good to be true...?

There is a little back story (conspiracy theory) about how the guy who invented them had the designs and prototypes stolen from his home blah blah blah. 

I've ordered some and will give them a go later in the year when they arrive. Has anyone else?

freitasm: It probably doesn't do anything. It is on them to prove it does. Just words on a website is not evidence.



yep, no real explanation on how it works either

This seems to disprove it (not going to attempt to embed the youtube)

Looks like a DC to DC voltage booster. Probably easier to just use rechargeable batteries and charge as required.

They will work with devices that don't include a built in voltage booster. Unfortunately most decent devices already include one. When you investigate the device you usually end up reading about this.

Maybe threads like this will shine some light.
http://www.candlepowerforums.com/vb/showthread.php?402188-Batteriser-Wonderful-Alkaline-Helper-or-This-Weeks-Smoke-amp-Mirrors

I have a Canon camera that is very picky about voltage and shuts down at times when there is still plenty of capacity left. If something like Batteriser maintains a fixed output voltage it would stop poor designs like the Canon refusing to turn on. Other equipment may not need a voltage booster.

This device is complete and utter nonsense.  

If it's not obvious from the fact that this is a DC-DC converter, which is going to have an efficiency probably about 80% and is likely as not to waste more energy, is going to mess with capacity detection (think safe shut down when writing EEPROM, FLASH etc), then Dave Jone's video above spells it out, and also his more recent one measuring AA capacity when depleted to various voltage levels.

Simply put, devices do not waste much of an AA's capacity, most well designed devices should get down to 1v or lower/cell loaded before giving up at which point there is so little energy left as your efforts are pointless, especially given the wastage of the batteriser itself in it's inherent inefficiency.  If you're losing 10-20% from inefficiencys in the boost converter to get that last 5-10% in the battery... probably not such a brilliant plan.

When you give them a go, remember this is geekzone, make your assessment more than just anecdotal.   Science!

Seems wasteful to duplicate the circuitry 4 times for a device that takes 4 cells.

If there was something that went around the entire series string of cells then perhaps it would be worthwhile, but that would just get really expensive kitting out devices that take more than one cell.

Yeah, i'm 100% sceptic on the ability for these to actually provide me with more power. However I do have a number of cheap chinese outdoor lights and whatnot that do appear to drain batteries quickly. I suspect it's just because they can't handle anything except full 1.3V but I should really do some checks on that. 

Either way, it's not a huge investment to give it a go and see if it helps any average electronics I have around the house.

It extends the usability of the batteries by running them down to 0V, but there is little energy left when they do get low.  With carbon zinc you will leak acid.  With alkaline you will probably leak some salts (but not acidic AFAIK).  I would not bother at all.




You can never have enough Volvos!

Cnahces are the cheap LED lights are like the marquee of lights I got in a letter shape, and a long string of little leds on some enameled wire, and just have 2 AA cells in series connected straight to the LEDs, so yeah those will probably be the only case that could benifit from the batterizer since it will hold a more constant voltage.

I stuck a USB plug onto it with a resistor and just use a USB powerbank to run them.

I offered them to run real life test by putting batteries [from the same pack] with and without "batteriser" in a device - e.g. XBox controller and run tests on my HV Battery Analyser which of course will prove that being a complete baloney. They did not take the offer.... And I have a feeling why. cool
