Battery power for LDG Z-817

 

Hi all,

merry xmas and enjoy relaxing event with relatives together.?

Could someone help please?
Z-817 tuner arrived this year as xmas gift for my son.?

I am worrying how to power it from inside battery pack ¡­? Is it possible to use recharchable AA cells or the alkaline AA needed only? In the manual the recharchable are strongly avoided cause of low voltage operating level and ATU improper operation in that case¡­

Is it really only alkaline AA cells with 1,5V needed or NiMH 1,2V could work please?

if LDG say alkaline AA needed only then i would go with what they say, they know best, i use alkaline AA battieries and they have been in their for over 2 years and still going strong

Hi Petr

NiMH cells would probably work, at first !? Their voltage is lower than AA alkalines, drops off even more with use, and are not recomended for that reason. Also the "shelf-life" (time to self discharge) of alkalines is measured in years, much longer than that for NiMH cells

I agree with Mick, use alkaline AA cells.? They worked well for several years in my Z-817.

All the best for 2023

Ok guys. Thanks.?

How you are preventing from the leakage alkaline cells damage inside the tuner? I have very bad experiences with leaked AA alkaline cells and damaged Mizuho radios and other electronics after longer time in¡­

With the amount of alkaline batteries that have leaked on me in the past few years (much more than in all years past) I would remove them if you know the tuner will not be used for a while.? Store them with the tuner so you don't forget them on a trip.

Take care,
Mark

The LDG Z-817 uses latching relays. Just wonder how little power is required between tunings.

Alkaline versus zinc-carbon cells seem old fashioned. They are both "cheap" and poorly sealed.

Suggest non-rechargeable lithium AA batteries and paint the battery ends and contacts with a light dab of vaseline or equivalent anti-oxiding coating. The coating is to avoid humidity driven bimetallic corrosion or similar metal corrosion between the battery contact and the spring contact. "A little dab will do ya! "

I use the lithium batteries in outdoor weather sensors and everything I can. I have never had a non-rechargable lithium cell leak. There are only two lithium (non-rechargeable and name brand) manufacturers I trust. Beware of look-alike fakes !

I was going to say the LDG-Z817 uses latching relays, so it saves battery draw versus other tuners that do not use latching relays.

Depending on how you operate your mileage my vary..

I did however set my FT-718 with internal battery pack in my sock drawer after field days, then Christmas even pulled it out to listen to a Santa net with friends in the living room where the fire place was making it nice and cozy.. Had to resort to a wall wart power? because the NICAD pack in the FT-817 would not even turn on the radio.. But the wall-wart saved the evening as the group that was over simply wanted to listen to the Santa Clause net..

Anyone that is anyone in Ham radio spends a lot of time playing with BATTERIES.. Matter of fact.. I can recommend 2 things...

#1. batteryuniversity.com ... The best place to learn and ask questions regarding batteries.

#2. My article on building a Battery Analyzer in MAY QST 2022 page34...

Amen to that!? We have been specifying and testing cells of different chemistries for quite a while here and published the results .

I would much prefer leaking alkaline batteries than leaking acid batteries. I find that a Q-tip or two with plain water (add a bit of vinegar or lemon juice if desired) will clean up an alkaline battery leak with no damage. Best to check any battery pack periodically to assure leakage has not occurred. This is particularly true for a pack enclosed in expensive electronics. I put my battery pack in a small case outside of the tuner and it can be a throwaway if damage beyond cleaning (or put it under the faucet and then let dry).

I change alkalines once a year regardless. Never sorry that way. I also silicone battery holder contacts and often the cell contacts too. External holders like Rich stated are disposable. Whenever I send for holders I get two or three instead of just one. Spares for the future and extras for new projects. They're cheap enough.
