What could be wrong when you insert a fully charges battery onto the blower and it begins to work but not with the speed it should and then dies out.

sounds like defective. personally I would return it to HD for a new one. HD money back 90 days from purchase.

Batteries are capable of telling lies and fooling a charger, even a modern so-called intelligent charger. The only reliable way to test a power tool battery is testing the voltage under load.

2 years old and it is now the third winter your snow blower is seeing and two summers - I wonder what you did with the battery during those summers?
Batteries hate being less than fully charged and a battery that is less than fully charged for many months will emerge less than optimum and even possibly useless.

Modern lithium batteries don't like being completely discharged because when recharged with a fast charger they get quite warm and it is the heat that tends to shorten their lives...

If any of this seems familiar - your battery is probably faulty.

Rosa, I think the only thing you did was get out the batteries and tried to charge them and then jut put them back in the camera.
Only a few things could have gone wrong.
One or more cells could have died, during charging. It can happen, special with batteries that have a uneven use. Like once or twice a year the camera comes out the box and then the batteries are charged. Even when you don't use he camera, make it a habit to charge the batteries every few months.
Then it could be your batteries are still in good shape and fully charged, but you put in one or more calls the wrong way around.
Please check carefully if all the cells are inserted correct.
If nothing works, and you can't check the voltage of your batteries, try another set of batteries.

Bike has magneito (thats spelled wrong ) On line youtube veido shows how to fix that.

Please make sure that the battery is clean and also the terminals within are clean. If you had been using the camera prior to the charging then the camera must work unless if the battery was spoiled by wrong charging. If you can use a multimeter to check the voltage which must be as specified on the battery label. Now make sure that the battery gets good contacts into the camera when inserted. If this wont work then it possible that there are errors within the camera and you need help from the nearest Nikon center.click the link below

This is what you experience when you battery is gradually becoming completely dead and cannot store enough power. It usually happens if you have been using it for quite a long time.
If you keep experiencing this kind of problem, then you may have to change the battery.
In other secondary and more complicated cases, you may be experiencing a partial contact between the battery and the terminals.
This could cause the battery not to deliver sufficient current as it should and it would prevent the device from working at full speed too.
In summary, you have to change the battery and make sure that the new battery charges fully before you begin to use it.
Hope this was helpful? Please comment for more information

If it is new Nano Li-ion technology- try to fully charge battery, they work FULL power until they discharge, so they die instantly, NOT like Nickel batteries go slower till they die, so maybe that is only your first impression that it shorts...

you most likely "over charged" your MP3 player...

A friend that worked for GTE advised me some yrs ago to do this and I have NOT had a problem with another battery since
when you get any new Battery charge it plugged in to the ac AND phone jack for a minimum of 24 hrs without using it.
all batteries have some memory and deminish power over time but if it was NOT fully charged to begin with as a yr goes by so does the battery life. hope this works,

This happened to me. The cause was the battery did not fit into the case, This led to poor connection of the battery. After I fixed the loose battery , it worked perfectly till today.
