We’ve looked at the AA Ansmann rechargeable battery, and were pleasantly surprised. We’ve looked at the performance of Ansmann rechargeable battery packs and their R/C line of products, all with great interest and delight. They have proven themselves time and again to be the hot new kid in town. We wanted to see if they could keep this trend running; so now we’re setting our sites on the larger rechargeable battery sizes: C and D cells.
Back to the Drawing Board
To the casual observer, it might seem repetitive to continue checking similar products from the same company, but nothing could be further from the truth. The power draw and usage of C and D cell batteries is significantly different than that of AA. For those of you that live and die by your rechargeable batteries, this is not news. However, for the uninitiated, we’d like to take a moment to explain.
A standard AA battery usually has an capacity of 2000mAh with a 50mA drain rate at a standard measurement of 1 amp. To determine how long a battery is going to last, you use the following formula:
Capacity (mAh) / Drain rate (mA)
The 50mA is the number of milliamperes a battery puts out over the course of an hour. The mAh is the overall capacity the battery has. So, a AA with a 50mA drain and a 2000mAh capacity will last an approximate 40 hours of continuous use (2000/50 = 40). Continue reading ‘Ansmann C and D Cell Rechargeable Batteries’
