| When looking at these batteries i notice 1600 1700 and a varioety of other numbers... what does this mean? How does it tie into what charger you must use if at all? |

Looking at the numbers you give, they must be the total charge of the batteries, when fully operational. Nominally it is the number of milli-amps times hours (mAh) that the things theoretically can deliver. So, higher numbers mean longer lasting time on the job. Mostly the instructions that comes with the batteries will tell what currents they want to be charged with. Imagine a fully discharged battery of 1800 mAh, at a theoretical efficiency of 100% it would take 1800 hours to charge it with 1 milli-amp per hour. You can figure it out.
By the way, for AA-batteries 1800 is about the max that you can buy these days.
The other numbers probably relate to voltage (1.2 or so, instead of the 1.5 that non-rechargeables give when fresh).
Does this help? |

| I think so... so the charger as long as it is a Nimh charger can work on any of these? |

I think so. I'm using the same kind of batteries in my camera and I'm really happy with them. They last longer than I expected between charges. I have 3 sets and I have never used my camera enough to wear out all three sets at without having time to charge a set. I think you'll be happy with them.

| 1800 mAh are the best you can buy. Monster power makes some great ones, I highly recommend them. As far as the charger goes, you need to make sure that the charger is capable of fully charging the 1800 mAh batteries. I have had bad luck mixing 1600 mAh batteries with an 1800 mAh charger and vice versa. I am not saying this is true with all, but be careful. Hope this helped. |
