Eneloop D adapter help

I've switched some of my devices to Eneloop AA's in Eneloop D adapter cells. The problem I'm having is that sometimes the cells don't seem to be making good contact with the device battery terminals. It's not corrosion, the positive terminal on the Eneloop D is quite small and I believe is the culprit causing intermittent if not positioned correctly. Is there anything I can do to improve the positive Eneloop D adapter contact with the device positive terminals?

You're going to laugh at me but... seriously, consider crumpling up a bit of aluminium foil.

I've done this in a similar situation where the tip of a cell didn't reliably reach the contact.

No, that's actually what I did, but I have shorting concerns. Some of the electronics are moved around so there is the possibility of foil shorting.

I'm not real happy about the positive side of these cell adapters. Seems it's tiny and almost recessed.

You can add a solder ball to the contact, but this will negate the plating and require periodic redressing of the solder to keep a good contact.

Tried cleaning up the terminal and putting a blob of solder on it ?

Or how about just shelling out on a proper rechargeable D cell ? - although I know for a fact that some of them are just AA cells wearing a D sized overcoat. The capacity figures are usually a giveaway.

Also, I dont know if its relevant in this case, but on the page at

theres a comment in the review section saying:

"Please note, to an AA to D converter with a Maglite you may have to insert a piece of metal, eg a 5 cent coin, into the spring. That prevents the back of the AA from shooting through the spring"

Ummmmm.....

I do not understand! An adaptor in this application is by its very nature a kluge. Use the right tool for the job. If you need D batteries, purchase D batteries. If you need rechargeable D batteries, then purchase those - al ong with the appropriate peripherals, of course. Similarly for 9-volt, A, A A, AAA, C & N batteries. Even lantern batteries, comes to it. They are all 'out there'.

I would not undertake to cut down a tree with a scalpel, nor would I wish t o do surgery with an ax. That is the level of discussion applicable here.

Of course, you will get all sorts of advice and offered all sorts of soluti ons with the full understanding that this venue exist to give bad advice an d bad solutions to simple problems, then discuss those same bad solutions a cross dozens of posts.

My solution turned out to be modifying the actual D cell holder itself and not touching the battery adapters. I simply screwed in a couple of bolts with head sizes larger in area that the original positive terminals. Then, cut off the thread part of the bolt ends and sealed off with liquid electrical tape to offset any short possibility. Problem solved.

By the way, some suggested using the right battery for the right job. To my knowledge, Eneloop doesn't make a D cell. Others do, but I only trust Eneloop. They do have multi AA to D adapters, but for the small amount of current drawn, I went with a single AA to D this time around.
