I've seen a web page with informal tests done on NiMH batteries in GPS receivers and under those conditions, there is little difference in performance between 1600 to 2000 mAh AA batteries. I've also found a web page that measured the true capacity of these various batteries and found that they often end up around the same regardless of rated capacity. It seems that some manufacturers are overly optimistic while others are conservative. I have 1600, 1700 and 1800 battery sets and while I haven't measured anything, I haven't noticed a difference that stands out. Rather than pay a premium for 1800-2000 mAh batteries, good 1700s or 1600s are a better deal. If you don't want to mail order, Wal-Mart and Home Depot have decent prices in my neighbourhood. Mike PS - I don't have the web URLs for the above. The first was a GPS enthusiast's and the second, I think, was a digital camera review site. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

As with many things, it's most economical to buy somewhat below the current state-of-the-art, so at the moment the 1500 - 1700 mA-hr cells are usually the best deal. However I wouldn't use any NiMH cells for an EPIRB since they slowly discharge when left unused for long periods. They're fine for a month or so, but the capacity decreases substantially with longer storage. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
