New battery re-charged but still wont fire

Check wiring again if it was running normal before ya changed battery

your title says camera ? but your post is in pride mobility ? but this will apply for any rechargeable batteries. the batteries could be at the end of there life ( they only charge so many times ) but cold and other things can drain them. heres a fix to try and get the full charge to stay full. you might have to do it a few times. charge batteries over night untill fully charged,prop the scooter up and jam the throttle on and just let it run flat ( anything else with full charge do the same.power on and let them run flat ) once there flat recharge again but drain the battery so it wont even light the lights.try it to see if the next charge holds ? if not try the same thing again. this is called calibrating..you might find after the first try it will hold half of its charge but will get better the more time you calibrate it. if that dose not work you will need new batteries. also try leaving them out of the item not in use to see if they drain on there own,this could give you a clue as to something being left on when there inside ? hope this helps

The Kindle touch and the Kindle FIre are great devices for your reading needs. However, there are times when it becomes unresponsive and freezes on you. Amazon says it is because the battery isn't charged properly or does not have enough power on it. It is advisable to charge your battery first before trying to reset the Kindle touch/Fire. If theKindle still has issues, then try the steps below on how to reset your Kindle touch/fire.

has spark? has fuel going to carb? if you smell gas from the muffler or carb then it not burning check for spark pull plug touch away from the hole so you don't ignite the vapors on the engine look for a great blue red spark

check for ignition fuse blown

It is possible that your Kindle Fire's battery has died. If you noticed the battery life diminishing before it wouldn't turn on at all this may be the case. Here is a site that has replacement batteries for the Kindle Fire:
3555A2L Battery for Amazon Kindle Fire D01400

Sounds like your power cord is dead and that it's not charging. If it's new bring it back to the store you bought it from and get a new one.

most camera are sold with "flat batterys" in them (its a fire hazard thing) so you need to fully recharge the batterys before use or the camera will just turn its self off,,,look at the hand book for charge times? dont try using it on half charged batterys you only kill off the battery that way,,,

My old 84 GPZ was similar,
sometimes start straight away
sometime spin until the battery was flat.
occasionaly start just as you let the start button go.
roll start straight away.
I believe the battery was putting out enough amps to spin the bike over but the voltage was down to 11.5 volts, this wasnt enough for the electronic ignition which needed nearly 12v to fire.
The reason it would start as the button was released was a slight voltage rise while the engine was still turning and it would fire.
I cant explain why it wont start after charging

A new battery solved it, plus I ran some battery conditioned called INOX in the electrolyte.
I'm in Australia, not sure if you can get this product .
Your bike sounds like a similar problem, hope this helps
