Why AA Rechargeable Batteries Don't Work In Some Devices - Part 3

This video is about Why AA Rechargeable Batteries Don't Work In Some Devices - Part 3

In this video I insert a pair of MAPLINS rechargeable batteries into an Apple Mouse to see if they are capable of powering the Apple Mouse.

In Part 4 I will test another pair of rechargeable batteries in the Apple Mouse, to test my theory that:  "the size of the battery and the tips dictates whether the rechargeable AA batteries will work as a substitute as an alkaline substitute"  #fixed1tRESEARCH #fixed1tMONEYSAVINGtips

Why AA Rechargeable Batteries Don't Work In Some Devices - Part 2

This video is about Why AA Rechargeable Batteries Don't Work In Some Devices - Part 2

In this video measure a number of Alkaline and Rechargeable Batteries to gain a detailed understanding of their size and shape, I then test the largest in an Apple Mouse to act as control.

In Part 3 I will test a number of the different sizes in the Apple Mouse, to test my theory.  #fixed1tRESEARCH #fixed1tMONEYSAVINGtips

1.2V Rechargeable Batteries Vs 1.5V Alkaline Batteries Which Is Best?

This question has arisen from comments to my recent video below on Why AA Rechargeable Batteries Don't Work In Some Devices:

Sadly its a common misconception, except in those circuits that have been deliberately devised to take advantage of the extra .3 volt. In reality the 1.5V battery doesn't stay 1.5V for very long as it drains the voltage goes down rapidly as does its current. It will reach 1.2 V pretty quick.  

The Rechargeable Batteries on the other hand retain their 1.2 volts under load and will do so until all the current has gone in which case the voltage dives down.  In fact I found a great chart:

In an excellent article by a fellow Radio Amateur Roy Lewallen. the link is at the end of this blog article.

The only time the lack of voltage has a real effect is where the speed of a devices is linked to the voltage in a cheap design, without constant current circuitry in place, and thats usually linked to a specific manufacturers devices. But the Alkaline Battery manufactures are more than happy for you to by their use once batteries, again and again...

But you don't have to believe me read this great article, it describes things better than I can here. I will increase your worldly 'geek' knowledge and save you money down the line.

Please share this Blog entry with your friends and relatives so they too can make the right decision.

Why AA Rechargeable Batteries Don't Work In Some Devices - Part 1

In this video series I investigate why some AA Rechargeable Batteries Don't Work In many Devices and Toys.  In this Part 1 video I look at the physical aspects of the batteries and how they make affect performance. In part two I will look more closely at the battery items. #fixed1tMONEYSAVINGtips
