Batteriser pre-sale starts today

[vaskidmark]

Somewhere along the line I mentioned these when they were first announced.  Now the pre-sale starts at Indiegogo.

I have no connection with them and will not make a penny off any sales.

If you are interested, you're welcome.

If you are not interested, sorry for having disturbed you.

stay safe.

Just a warning to folks, the claims are three inch shy of a scam. There CAN BE improvements, but it is of a varying scale.

As I recall, (and yes I'm too lazy to look it up) there could be reasonably significant improvements for an odd subset of poorly designed devices.  Maybe enough to justify $5 a pop for a few of these things if they live up to the believable parts of the claims.  If they turn out to have microscopic cold fusion reactors inside to actually do what they say, then they're worth buying for all your devices.

Frankly, the ones I'd want would be the LR44 and CR2032 sizes...though especially with the on-key remotes these days, I can't see why the stupid remote can't charge from the car when it's slotted in.

A new $2.50 battery sleeve called the Batteriser, coming to Amazon this fall, promises to extend the life of your batteries up to eight times longer by drawing out their remaining power -- which you were about to throw in the garbage. The tiny, 0.1 millimeter-thick stainless steel Batteriser sleeve features an incredibly small circuit board, built to tap into the battery's remaining energy.

My old TI-55(?) calculator ran on a 9V 9UV battery, but I got a little inverter pack with it which would boost a A or AA cell to the 9 Volts to run the calculator, and fit into the regular batter hatch on the calculator.  But it required a little transformer in it as well.

So it's conceivable that "somehow," they fit an inverter in that sleeve (maybe in the bottom, negative side?) which would still fit in the battery compartment and take the "dead" 0.6 volts up to the full voltage of a fresh battery. 



Note I said "conceivable."  Over the decades, I've constantly been amazed at what can be done... like a laser gyroscope that can fit on your pinky nail, f'rinstance.

EEVBlog has posted a new vid examining how to calculate alkaline battery energy reserves.

Because pinky nails without gyro stabilization were a problem that just had to be solved.

When they say their gizmo can make batteries last up to eight times longer . . . they don't specify the device, duty cycle, or how many standard deviations away from the mean improvement their "eight times longer" actually is.

A healthy dose of skepticism is in order.

(1) When they say their gizmo can make batteries last up to eight times longer . . . they don't specify the device, duty cycle, or (2) how many standard deviations away from the mean improvement their "eight times longer" actually is.

(1) Good point.  Batteries (cells) do recover somewhat between uses, so duty cycle may be important... if it's not an outright scam.

(2) I doubt that most users would understand the standard deviation bit.

(3) Twue, twue, vewy twue.  I'd like to see some technical details, but my supposition above (Reply #5) about a teeny-tiny little inverter (or converter, more properly) still seems most likely.

Go to the EEVblog link above. He links back to his original Batteriser analysis (analysis summary: they're useless in modern devices).

It's about as solid of a claim as 'Could save you up to $500 on your car insurance!'.

Indeed.  Brad's linked video is very good at explaining it.  Now, I think that 'straight resistive loads' are more common than EEVBlog thinks - flashlights are a good example of one of those, and while it's only 1 type of load that takes batteries, it's probably the single most common.  But still...

You're probably better off doing the old 'trick' of once your flashlight is too dim, simply stick the batteries pulled into your remotes. 

Or the 9V from the fire alarm into your multimeter or stud finder.

The eevblog is dead on for this one.  This is worse than useless, and for even resistive devices, the higher current draw near battery EOL is bad for so many reasons, beyond the really bad potential safety issues.  The only time this would be useful is on a device with a really poorly designed hard voltage cutoff, that draws little to no power...in other words...basically nothing.

And even then, it's only the flashlights that aren't using regulated LEDs.
