Thanks Jay.

I had a bad run with them in the early 2000's in some UHF CB's so have avoided them since, these days I use ones from JayCar which seem to work well. The last batch of alkalines I got from Kmart have not been great either.

But this discussion about Duracells is a completely different thing because in the past few years they have been known to leak even when new and definitely before they were used up, which is something we haven't seen in other batteries.

Re: List of *Official* UltraLight radios?

Paul Blundell
 

Hi Peter,

Here is a link to the list, it is from 2010 so many of those radios are no longer for sale and many new ones have come on to the market.


While these are the guidelines, nobody is going to lose their mind if you use one that is slightly outside these specs, we might need to look at updating the list.

Thanks all.

I have been looking at these:

https://www.jaycar.com.au/aa-alkaline-eclipse-batteries-pk-4/p/SB2425

I use NiMH cells (Eneloop) exclusively.

If I *had* to get non-rechargeable (because I forgot to bring extra
NiMHs!) I would only get alkaline cells. I'm surprised that
carbon-zinc cells are still sold - it's obsolete battery chemistry.
I'm sure there is some niche where they fit but ... go for the
alkalines if you don't want to do rechargeables. If you are really
worried about leakage (which is a real thing and damaging), get in the
habit of popping one out when you are done for the day. The cells are
almost always in series, so popping one out breaks the circuit.

I did have my PL-606 apart the other day (I should post that video)
and found that even with the AAs out of the radio, there is a
capacitor or something in there that holds up the clock and the
thermometer. I was confused for several minutes!

Hello. Agree totally with Jay. I’ve had Duracell batteries leak more than once. Actually several times,Never had a single issue with Eveready  batteries.. That’s all I buy now! A couple years ago wrote a letter to Duracell regarding the problem and NEVER  got an answer. It’s amazing that such problematic batteries still keep selling.

Hmm I had a Ozzipole (Buddipole) I was making for HF... It could easily be adapted to FM freqs. You got me thinking.

Directionality is a great advantage for MW and FM chasing.

Thanks Timothy.

I did try a few different angles. I have also just purchased a second set and an extension cable so I can try a few side by side comparisons with another radio.

Re: FM Aerials

First session with the $7 rabbit ears has produced two new stations logged. I have tracked down somebody locally who has a few of these to give away and some cables, my plan is to get a pole setup to give myself some more height.

If you live near an Ikea, their Ladda 2450 mAh AA batteries are made in same factory as Eneloop Pro’s.

Paul,
Eneloops are rated at a minimum of 1900 MAH. Some of them are rated higher (2200 MAH I believe), but the trade off is that they self discharge a bit faster and do not give as many cycles. Self discharge is not an issue if you just top them off before use, or use them within a week or so of  using them.
Most alkaline batteries are around 2500 MAH. But the voltage on alkaline cells  drops faster and will nosedive under high current drain. . Meaning that they also are pretty bad for  anything that draws much current.
Often the NiMH batteries actually last longer in any given application. 
BTW, there are many brands of NiMH cells, often cheaper, but fully serviceable. It seems that most of the test/review sites rate the Eneloops at the top of their lists.

"Battery capacity ratings are meaningless when used to compare different types of batteries or to compare the capacity of batteries powering different types of devices.

This means that you may not be able to predict how long your electronic device will run just by looking at the capacity rating of a battery. For example AA alkaline batteries typically have a capacity rating of over 2,500 mAh and AA NiMH batteries have rated capacities of only 1,200 to 1,900 mAh. But when it comes to actually powering an electronic device like a digital camera, the NiMH batteries will often run the device for three or four times as long.

This is just something I found in a quick search. Lots more info is out there if it is of any interest to you.

That is good to know, I have not used them for years, mainly using rechargeables or cheap one from Kmart or Jaycar.
