Handhelds and alkaline batteries
I have an Icom transceiver and have no problems with batteries. I too
use the alkaline batteries. Ross Ross Oliver wrote: I recently purchased an Icom A23 Sport handheld transceiver, which uses 6 AA alkaline batteries rather than the rechargable NiCad. I chose the Sport model because I plan to use it primarily as an emergency backup, the alkalines will hold a charge much longer than the NiCads. The radio receives great, but it will not transmit at all. Even with brand new name-brand batteries, the "low battery" warning comes on as soon as I key the PTT, and the transmission is so badly clipped that it is unreadable. I'm guessing that the alkalines simply cannot provide enough current to adequately power the transmitter. Has anyone else tried transmitting using a handheld powered by alkalines, either the A23 or any of the other brands? I'm thinking about trying the Sporty's model next. It uses 8 AA rather than the A23's 6. Ross Oliver |

Alkalines have a problem when you get to the power levels we are talking about
for transmit. They last a mercifully short time in most HTs. We've found that popping for the NiMH cells is far better from a time and life point of view. Try www.thomasdistributing.com Probably the best price in the country.

I have had a JRC and I have the new Vertex. Both work great on alkaline

I use alkaline batteries in my A22. They have worked for over a year or
so. But I only use to get clearances and check ATIS without powering up the plane. jerry Has anyone else tried transmitting using a handheld powered by alkalines, either the A23 or any of the other brands?

I don't own Energizer (ENR) or Duracell (G) stock and I don't think Jay does
either. We just stopped by the closest battery booth and that's what was readily available for alkalines. "mike regish" wrote in message news:UOcYa.54566$cF.19421@rwcrnsc53... Bet he owns stock in Energizer... I use Duracell in everything. (And no, I don't own any stock) mike regish "Greg Burkhart" wrote in message news:YocYa.81797$o%2.37792@sccrnsc02...

We've found that popping for the NiMH cells is far better from a time and life point of view. For an emergency only radio, NiMH are about the worst battery to use. They have a self discharge rate of 10% per day. The Lithium Ions are the next best then NiCd. Of course the self discharge rate of alkaline batteries are a lot better than any of the rechargeable but they don't do well with high current loads that some electronic equipment need. The non rechargeable Lithium batteries are the best in that regard, they last a long time, lowest self discharge rate of any battery and they can take the high current loads, the only down side is they are expensive, especially if you go to the corner drug store where they some times will charge $8 or more each, if you look around on the internet you can get them for less than $2 each. Of course that doesn't do much good if your radio doesn't have a pack that will take the CR123 lithium batteries. -- Chris Woodhouse Oklahoma City "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -- Benjamin Franklin, 1759 Historical Review of Pennsylvania |

See? Already I'm thinking like a politician. Normally, I would have said,
"Bull$#it", but instead I'm saying, "Isn't that an interesting untruth." {;-) Jim Chris W shared these priceless pearls of wisdom: - -For an emergency only radio, NiMH are about the worst battery to use.

Looks like I was wrong NiMH batteries have an even worse self discharge rate than I had remembered and NiCd are next and then the Lithium Ion http://www.allegromicro.com/techpub2/cadex/index32.htm -- Chris Woodhouse Oklahoma City "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -- Benjamin Franklin, 1759 Historical Review of Pennsylvania |
