- Eneloop D adapter help - 5 Updates
- switching most of my batteries over to Eneloops, but..... - 3 Updates
| Hem Jung <hemjA@netco.net>: Mar 06 08:38PM -0500 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. -- _____________________________________________________ Knowledge may be power, but communications is the key dannyb@panix.com [to foil spammers, my address has been double rot-13 encoded] |

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've done this in a similar situation where the tip of > a cell didn't reliably reach the contact. 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 https://eu.nkon.nl/aa-naar-d-converter.html 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" AT |

The ones I'm using are the Amazon Basics Ni-MH variety. I didn't notice they had Li-ion ones as well when I bought a set. |

Don't you get tired of having to recharge it ? > I didn't notice they had Li-ion ones as well when I bought a set. ** Not Li-ion, non rechargeable lithium. There are lots of sub types of "lithium" - most commonly they are 3V cells. So three inside a 9V unit. https://en.wikipedia.org/wiki/Lithium_battery#Sizes_and_formats .... Phil |
