RCU Forums - Battery Testing

The resistance is in Milli Ohms, not Milli Amps.

Here's a good article on this: http://www.rogershobbycenter.com/lip...po_discharging

This begs the question: how low should it be? Unfortunately, there's no easy answer for this. It's all dependant on your use case and battery. What is great for one battery may be terrible for another. Based on my online research, combined with my own experience and findings, I would say, as a general rule, a per cell rating of between 0-6 mΩ is as good as it gets. Between 7 and 12 mΩ is reasonable. 12 to 20 mΩ is where you start to see the signs of aging on a battery, and beyond 20mΩ per cell, you'll want to start thinking about retiring the battery pack. But this is only a guide - there is no hard rule set here. And if your charger doesn't give you the per cell measurements, you'll have to divide your total count by the number of cells in your battery to get an approximate per cell rating.

Those readings are per Cell, not battery...many chargers only give you the per battery resistance, not individual cell ratings, so verify the readings before condemning a battery.
