Rechargeable batteries Mono-D
The thickest one we know is this Mono-D battery, also called LR20. It was invented at the time for equipment that used a lot of electricity, such as toys, doorbells, appliances with a motor, flashlights, etc.
Battery technology was to less advanced than it is now, so they couldn’t store much in them than they do now, so they had to be large.
Because it is thicker, more power can be stored in it. This means they last longer, making them more practical for some purposes. A good solution, otherwise you will keep changing batteries.
Nowadays they are not used much anymore, so they are more expensive. The version we supply contains 2500mAh or no less than 10,000mAh. But you can also use an adapter from an AA battery.
This rechargeable battery also pays for itself after charging only 3 times. Don’t forget that it will last for years, because it can be charged up to 1000 times! Once again proof that a rechargeable battery are cheap.
