Trying to charge and not fry my batteries

[cdwb77]

I did some searching, and couldn't find an answer specific to what I need to know, so I apologize if this isn't the right forum for asking this question. I'm trying to label my cords so I only use them with the appropriate batteries, so I won't fry the batteries or burn down my house. Here goes:

I have 4 different batteries, all with 510 threading:

• Joyetech 510 standard auto 220mah
• mini Ego 350mah
• Ego 650mah
• Ego 900mah

I have 3 USB charging cords, with 510 threading, that all say "Input: DC 5V", so I assume these can all be plugged into either my computer or a wall-plug that says "Output: 5V". Please tell me if that is incorrect.
My USB cords OUTPUT say:

• DC 4.2V 150mA
• DC 4.2V 200mA
• DC 4.2V 420mA

I know the 420mA cord would fry my 220mah battery so I won't try that, but will it be fully charged with the 150mA cord? Is the 200mA cord ok to use on the 220mah battery also, or should I use it only on the 350mah ego? Do I need to set a timer?

Should I only use the 420mA cord on the 650mah and 900mah batteries? Will they get a full charge, and do I need to limit the amount of time that they charge?

Thanks in advance for any help!

These you should be able to charge with the same charger:
[*]mini Ego 350mah
[*]Ego 650mah
[*]Ego 900mah

The 510 cig-a-like probably came with its own charger and I would use that one for it.

Use a file label or piece of masking tape to write what charger goes with it for future reference.

As for limiting the amt. of time they charge, NEVER leave a battery on the charger overnight, or when you can't be around to monitor it, and ALWAYS take batteries off the charger as close to the time as they show fully charged as possible.

Also, let the "rest" for an hour or so before using them---that is best practice .
