Anything strong enough is likely to require case modification.

Thanks Dave, but powerworks.com is a renewable energy company ...

Ideally I'd like a supplier in the UK.

Yes there is I have the battery and the plug for my 817 qrp rig. From Powerworks.com ??

Is there a dc powerpole adapter for this radio that will fit through the hole in the leather carry case?

Dave,
I have an LDG Z11 tuner as well and bought the interface from W4RT called the one touch.? It has a loop through for the data port so that you can use rig control, N1MM logger, etc.? However, I don't think W4RT is still in business.? I have seen used one touch interfaces on ebay and other sites.? It works well.? I can't find W4RT website.

My LADDA cells arrived today and you're right about them being oversize. I'm not happy trying to force them into the tray so I will use them to make an external pack and charge it with an airsoft charger.

I took a good tooth pick with a very small amount of "Crazy Glue" on the end. I stuck in and after about 1/2 a minute or so, pulled out the tip.

I purchased a 817ND recently and it had the same problem. It was stubborn but I was able to pull it with a very fine "dental pick" type of tool. No harm no foul on the sale, but the rig wouldn't power up when I received it. Now it's working fine as my portable satellite uplink rig. 73

Thank you Ronan, I had forgotten that the whole cell case apart from the circular bottom plate is positive and I have the LADDAs in there right now. That was a forced option because the '818's battery pack has withdrawn its cooperation, and a replacement 1900 mAh pack is simply not fiscally justifiable for myself.

The LADDA cells are a tight fit in that plastic tray, right enough, but I've not had any issues with them not making connection. They are pressed quite firmly to the cells in the adjacent rows though so it is wise to check the integrity of their plastic wrap when fitting..... Things could get a little toasty if it gets damaged....

Your mention of Eneloop cells is interesting, Steve. There has been much chat elsewhere (candlepower forum, I think) to suggest that the LADDA cells are rebranded eneloops as they are made in the same factory in Japan.?

I also have had the experience that many NiMH cells, especially the slow self discharge/pre-charged cells are larger in diameter than their alkaline counterparts and will not fit in some equipment.

Another gotcha is the button height. If you compare any alkaline cell next to a NiMH rechargeable you will see that the case on the NiMH is longer and the positive button height is shorter.

This proves to be a problem on devices that have battery compartments with a recessed contact.

I have soldered #2 brass washers in places or used little bits of foil to mitigate this problem in some things.

The worst is older equipment that was made decades ago before a lot of these cells were even available. (Think Radio Shack CB walkie-talkies)

Happy tinkering!

I'm aware that I wasn't anything like the first, but I flagged up the IKEA Ladda cells some time ago, probably on the groups.io Elecraft KX group and was indirectly rebutted by some foreign correspondent for suggesting that folks should consider anything other than Eneloops in their expensive radios. So what? I hear you saying ... Well that's what I thought too, but in addition "your loss Mate".

I just wanted to advise that these most excellent Ladda cells (probably like most NiMh LSD rechargeables?) are nominally 14.3 mm diameter, while standard alkalines are a tiny bit smaller. There may only be 5 or 6 thou' in it, but miltiplied by four rows it is sufficient to resist the cell holder's spring forces. Since the cell holder will only install without all the cells in-situ, this means that cell continuity is a lottery and although you may get lucky, the radio mostly won't power up in my experience. You can push two of the rows of cells in one direction, but the other two rows are difficult to pull in the other direction using just finger tips. Moreover, for what is essentially a portable radio there is the nagging doubt that once working, they will dislodge with loss of power.

I have neatly cut away the central rib in the cell holder by repeated scoring on each side with a home made miniature metalworker's adjustable back marking gauge and using a scalpel (Exacto knife?) at each end followed by repeated flexure and it was actually quite easy to make a neat job of it. This has ameliorated the issue to some degree but it is not a total solution. Of course this may be confined to my own use case but I expect not. If anyone else has experienced this with LSD cells I'd appreciate a heads-up for any "cure". I cannot point my finger at Yaesu this time because they never intended ths radio to be used with rechargeable cells, but they've forced the issue by refusing to investigate superior power options. Even an accessory replacement battery compartment door with a pressing that would allow 18650s would be a start. It's shameful.
