Stack 10440 Li-ion 3.7 V

The inadvertent use of Li-ion battery 3.7 V 10440 can burn a toy or remote control! As they have the same appearance and size of a AAA battery (stick as know in Brasil), some unsuspecting can try to use them and not realize that each voltage is 3.7 V instead of the traditional V 1.5!

However, If you want to risk it may be that this battery works very well in location of a common. For this you have to use a pile of these in conjunction with a dummy 0V. The total voltage of a set of two batteries will be 3.7 V while two common cells add up to 3.0 V.

Most equipment does not burn because of 20 to 30% higher voltage. Of course there is this risk, But if everything works you can have great gain with the Exchange. Li-ion cells can carry a lot of power and will last as long or even longer than the alkaline. And are rechargeable!

Below the stack in a tester! She fully charged can reach 4V.

Tested here at home in a remote and walkie talkie and is working perfectly for months! Amazing! In a toy my son these batteries lasted more than 6 months with just a load, more than ordinary rechargeable batteries! Be aware, However, the tension is higher and there is a risk of burning equipment! I leave below link to these cells and to the dummy.
