Batteriser - Evaluating their claim to get 80% more energy from batteries


Recommended Posts

Hi there!

I think this new product called Batteriser is a bunch of marketing hype and won't stand up to any real tests.

I would not recommend anyone purchase this product and instead wait for the reviews to come out and to be very skeptical

It's a stainless steel sleeve that goes over a battery and has a micro DC booster to step up the voltage to 1.5V to "get 80% more out of battery" - they used to say 800% longer

Their website http://batteriser.com/

I try to keep an open mind and interested in any thoughts people may have. 

Dave Jones over at the EEVblog did a debunking https://www.youtube.com/watch?v=4iEshd6izgk

My thoughts:

  • No battery level monitor or low battery warning would be very annoying
  • Can it really keep up with the high current drain, can it really handle several amps?
  • Shorting risk, would not want to be shorting out D cells with these things
  • Battery leakage risk due to over-discharge
  • Cannot use with rechargeable batteries due to over-discharge reasons
  • Company is dodgy as, very shady testing methods. They said 1.4V - 1.35V for normal battery is considered "dead".. gimme a break
  • There is only maybe 10% of battery capacity left at 1.1V, and the boost converter will need to draw current from this 10% to operate and the efficiency will be terrible.. not worth it

One thing I don't know and would like to know is, would a product hit its "cut off voltage" and turn off if it dipped under that voltage of say 1.1V only for a moment? Say with a camera when it takes a flash and charges the capacity, there could be a voltage sag which takes it under 1.1V for a moment, but then would shoot back up. Would this Batteriser then be useful to stop this? With a new battery that voltage may only drop momentarily to 1.3V, but over time it drops to 1.1V for that very short period of time..

Interested in your thoughts!

I use AA alkaline cells only for very low current products where the idle current of The Batterizer is higher. Then it wastes more power than it saves.

I use AA Ni-MH rechargeable cells for high current products that The Batterizer cannot supply.

The marketing people know that many people are gullible and believe their lies.
