Is there a store or company that will replace batteries for digital watches?
Brownstone21 asked:
I have a digital watch I got from a friend of mine. He told me before giving it to me that the battery is bad and may die soon. Now it has died and I am wondering if there is a store or company (I am willing to ship the watch for them to fix it) that will fix my watch. I would also like to know the cost of this. Thanks!

How much does a battery weigh that can store a million joules of energy?
jim m asked:
If a good energy storage system was available electric cars would be a lot more useful. Batteries do store energy so how much do they weigh per megajoule of storage?
