Battery problems with Nikon Coolpix L100 Camera?

I bought it off Ebay so i cant return it and get a new one from a store etc etc. The firmware is updated to 1.1 and the option for rechargeable batts is on. But when i put in brand new fully charged batts it shows that the battery level is low.

is there anyway i can take it some where and they can install a different battery (like a battery pack?)

Im using this to help shoot my honeymoon and with batterys that die so fast im not sure what to do. I just bought it and my honeymoon is 2 weeks away so returning it and finding a new one and getting it here wont work.

Any help?

Waterproof cameras: which is better for the price, Panasonic or Nikon?

I'm trying to decide between two waterproof point-and-shoot cameras:

PANASONIC LUMIX DMC-TS5 BLUE + BUNDLE $320
Shape is easiest and most comfortable to hold, but not as streamlined and would be bulkier in pocket. Heavier than the Nikons. I was told this one is 'the best' by two different sales people.

NIKON COOLPIX AW110 + BUNDLE SPECIAL $260
This one is last year's model on clearance and includes Photoshop Elements 11.
Feels lighter and has a slimmer design that would be easier to slip in and out of my pocket.

My purpose would be 99% land use, especially landscapes, nature, outdoors, but also people, indoors, night pics, etc. I may use when traveling, hiking, trekking, snorkeling or doing other activities where the waterproof/rugged features as well as GPS would be handy. I don't plan on diving for needing deep underwater pics, but who knows, I am in the future. Camera must be easy to use as I am usually active and only have one hand free when taking photos.

I'd like good quality pictures because I share them online and often print them.

So, do I get this year's Panasonic Lumix DMC-TS5, touted as 'the best waterproof camera', or save some money and get last year's Nikon Coolpix AW110, the 'second best waterproof camera'?

Where can I learn how to use digital cameras?

I currently have a Nikon Coolpix P80. I recently have really gotten into photography and I would like to get a DSLR camera during Christmas sometime. However, by the time I get the new camera I want to know how to use my current camera very well so that I can know how to use the new one proficiently as well. I am at a very beginner level currently. Where can I learn how to become a good photographer. I know I have to learn though experience but I am very willing to spend hours taking pictures. Where can I learn what all the terms mean and how to adjust them to do what I want them to do. Thank you!

Why does my point and shoot camera have such a big zoom compared to a DSLR lens?

A while ago I was into photogrophy and I got a Nikon Coolpix P80. Recently I have gotten a lot more into taking pictures and I have been looking at a lot of DSLR cameras and their lenses. Why does my Coolpix have an 18X zoom and is 27-486mm, while a normal DSLR kit lens is 18-55mm. The Coolpix has a much larger range. Why is this? How can they do that on the Coolpix normal lens? Sorry this is a beginner question, but as I said I am just getting into it all.
