Both batteries produce 1.5 volts of electrical current but after that the similarities between the two batteries stop. A standard battery has a capacity of 500-1000 mAh (milliamps an hour) which is equivalent to 5-1 amps an hour. Alkaline AA batteries on average have a capacity of 2400 mAh. What does this mean since an alkaline battery has a higher mAh?
The mAh capacity of a battery determines how long the battery will run for.
So what this means is that a 1000 mAh standard battery will run for under half the time that a 2400 mAh battery will run for. Both batteries are similar in that they do not run well in high drain devices such as cameras, MP3 players, etc., but you can buy high drain alkaline batteries to use in high drain devices which gives alkaline batteries an edge.
While many people are switching to rechargeable batteries to save money some people do not want to be bothered, but what do you do when you are in the middle of a game and your battery dies?
Batteries work through electrochemical reactions, and rechargeable batteries are able to reverse the electrochemical reactions to restore the components to their original state.
Standard batteries are not able to restore themselves to their original state at all, but alkaline batteries have the ability to restore themselves in small quantities.
Your alkaline battery will never be restored to its original state but after leaving it off for about half a minute you will have the ability to get a small quantity of power from it.
One of the major setbacks about a standard battery is that for some reason they tend to be more expensive than an alkaline battery. So make a smart decision to buy an alkaline battery, and if you are using it for paintball, purchase a battery specifically designed for paintball equipment.
