There are already 100 of times already that when I travel, I always forget to charge my battery at home and I tell you it is really pissed me off. It is indeed good if we always have an extra rechargeable battery in our bag so even we don’t get to charge our battery at home at least we still have one extra to depend on while traveling. So if you are like me who travels from time to time, you may want to purchase rechargeable aa batteries here, I am certain it could help you big time especially when the battery is drained and you were in your utmost adventure. If you are still not convinced why you need to have another rechargeable battery, I will site you an example of my one of my travels. I was with my daughter in one of her competition, we had to travel for that competition and when we arrived at the place, I was so excited to click the views in front of my eyes but I was so disappointed when the battery of my camera just didn’t work. It surely pissed me off!
