New ultrafire 18650 4000 mah li-ion battery. How do I let it charge for

This side tells you everything about charge and discharge of the ultra fire gold, but red is almost the same. Test of UltraFire BRC18650 4000 mAh Brown Gold

Tip #1: Wait at least 15-20 minutes after you drain a battery to charge it.
This allows the battery to cool down before each charge cycle. I would make sure the battery is cool to the touch before charging it again, but 15 minutes should be alright.

Pointer #1: If the battery is hot after use, then it is a good sign that your battery is getting old.
Anything warmer than about 140 degrees is dangerous; if your battery is this warm after flying, it's time to replace it. I wouldn't use it anymore so it doesn't explode. This is a good indication that in the near future you should look to getting a new one. I would recommend a higher quality / mAh battery (keep the same voltage, though) if the battery running out is a stock battery.

Tip # 2: Wait at least 15 minutes after charging a battery to use it.
Once again, this is to let the battery's chemical processes have a break.

Pointer #2: Battery terms to understand when buying a RC battery.
mAh: Milli Ampere Hour. This is basically the electric charge transferred by a current of one milliampere for one hour. I'm no electrical genius, but the higher the mAh, the longer a battery will last per charge. This is the one part of a battery that you can change without damaging the heli.
Volt: The electrical pressure. Basically this determines how much power can flow to the motor. For lipo batteries the voltage comes in multiples of 3.7 volts, or 3.7 volts per cell.
Cell: An independent 3.7 volt battery.
If you would like a little more in-depth explanation, I found this howstuffworks article helpful.
Litium-Ion (Li-Ion): a type of battery that has a rigid cell structure and shape. It is safer than a lipo battery, but not as efficient.
Lithium-Polymer (Lipo): a type of battery with a flexible cell structure and shape. Lipos can catch fire and explode if mistreated or dropped on a hard surface. BE CAREFUL! Although more dangerous, they are more efficient than li-ion batteries and can come in practically any shape with the same cell count.
Look below to see how the li-ion (on the right) has two defined cylindrical shapes in the package, whereas the lipo to the left is just a rectangle with no visible curvature or cells.

wait, do you have Li Ion batteries or Ni MH?

I think that Kodak recommends Li Ion batteries which have a higher voltage on them.

I got some generic Li ion battery packs off of Amazon.com, with better specs. than Kodak, and they work fine for my Easyshare z1485 IS camera.

It cost me like $80 to get the charger and two battery packs that are Li Ion, but it's worth it.

My battery packs are rated at 2000 mAh 3.7 Volts each. It's the voltage that counts. You see, if you would split that in half, the voltage for each AA battery is 1.85V which is much higher than the 1.5V that regular Alkaline or Ni MH batteries are rated at.

I tried Alkalines, and Ni MH to no avail. But, the Li Ion batteries, did the trick for me.

Good luck on this 'repair' or battery upgrade.

Try cleaning the battery contacts in the camera first with a pencil eraser and then with a cotton swab lightly dampened with rubbing alcohol.

From the link you gave its seen that its comparatively lower than the other series.. Brand: HP Laptop BatteryBattery Info: Li-ion, 4400 mAh, 11.10V, Black, 310.00(g), 205.15 x 59.20 x 37.50 mm Rating:
