You can get more use out of a 9 volt battery and save money.

A lot of times if you plan on using electronic devices without a power source batteries are a must. The great thing about buying 9 volt batteries is if you open them up they have small batteries inside that can be used for triple A batteries. So if you go camping and carry devices with you that require 9 volt batteries and triple A batteries, you can just buy 9 volt batteries and save some money.

 

I just keep enough rechargeable batteries on charge.

 

@Arkane I was saying that you won't have a power source, so how would you recharge the batteries when they loose power? The whole idea is to buy enough batteries of two different kinds without spending a lot of money, if you want to use your devices where there's no power source our outlets.

 

Never have thought of that, thank you for the tip. You can also make your own 9 volt battery if you have several spare 1,5 Volts AA batteries (6) and aluminum foil.

 

Nice thought indeed,electricity is one of the most important thing plan have an adequate plan about before embarking on any mission or journey. An individual is advised to have spare batteries as well as any chargeable gadgets to help create security or for visualization at night. Adequate preparation should be taken on what can help and support on a mission or journey not what has no value on what you want to do.
