+Prime Suspect Posted March 19, 2002 Share Posted March 19, 2002 New Rayovac battery developed - 4 times the charge of an alkaline, and it can be recharged in 15 minutes. See the story here. Quote Link to comment
+GOT GPS? Posted March 23, 2002 Share Posted March 23, 2002 Long wait for the new batteries, wont be available till mid to late 2003. Till then, the only battery that makes sense, is the Nickel Metal Hydride Rechargable Batteries. Quote Link to comment
+Hawk-eye Posted March 23, 2002 Share Posted March 23, 2002 Still a little skeptical ... quick charge hasn't equaled output and battery life so far ... and if it's that far out ... sounds like they're still a way off perfecting it. Looks more like they're trying to up stock value by press releases. Whew ... do I have an attitude this morning or what? Quote Link to comment

+Renegade Knight Posted March 27, 2002 Share Posted March 27, 2002 I must be blind. There didn't seem to be a part that said anything about the storage rating of the battery. Speaking of that. I've got 1600mah NiMH Panasonics. I've seen 1800mah NiMH's but I've never found out what the rating of the typical alkaline battery is? Anybody know? Quote Link to comment

They're usually about 2800 mA-hr which looks really high, but needs a caveat. The mA-hr ratings are done with a very low current load - usu. only 20 mA. Alkaline cells can deliver their total charge very efficiently when the current is kept that low, but with their high internal resistance, they can't deliver nearly as much total energy when the current draw increases. At the typical GPSR current drain of 100-150 mA, the alkaline cells have a capacity of around 1800 mA-hr, or about the same as the better NiMH cells. And at the even higher currents of 200-500 mA of some digital cameras the capacity of alkalines drops even lower to significantly less than 1000 mA-hr. That's why NiMH cells are frequently advertised as outperforming alkalines in uses such as digital cameras while they're about equal per charge in GPSRs. Quote Link to comment
+rdw Posted March 29, 2002 Share Posted March 29, 2002 I was in the local Wallyworld a few days ago looking at FRS radios and noticed that Energizer now has 1700mAh NiMH batteries. They are not the old blue and gold, but rather green and silver. I think they were at the same price as the 1600mAh, a 4 pack for $11.97 Just thought I would pass the word. rdw Quote Link to comment

This -may- be an error on Fry's part since the Fry's sticker says they are 1700's but the batteries and their packaging says they are 1800's Quote Link to comment
