I was fast asleep when these came up for discussion....
My problem is the alarm system for my daughter's dead 1997 VW Golf GTi contains 5 AA size cells soldered in series. The installed cells are Varta NC 2000. Naturally Varta no longer admit to such an item or any specification. Is a replacement available? The charger forms part of the alarm circuit and I have no idea of it's intelligence level but assume it would never understand NiMh. Any thoughts? regards -- Tim Lamb |

IIR the early Golf was factory fitted with a Gemini alarm unit but in the
late 90's they used Cobra,both consisted of volts drop sensors via the courtesy light and sonic "air " sensors along with Ignition cut out and indicator flashers. The Gemini system is 3 part; control unit inner bulkhead ,air sensors behind radio and sounder under bonnet whilst the Cobra was a single encapsulated unit under the bonnet both had 6V Nicad packs as you describe used primarily to run the sounder in case of 12v failure. If you get really stuck repost and I will rummage through my old car gear for a pack but it may be as bad as yours.I do have 2 6 stick sets you can have if you want to butcher 1 cell out. Let me know but am going on jollies in 12hrs be back next week. CJ "Tim Lamb" wrote in message ... I was fast asleep when these came up for discussion....

I have some dead power tool batteries which might still have some working cells. Not AA Get those Sanyos. Use plumbers flux and a BIG hot iron to solder em. Physical size not much of an issue as these are just wrapped together in heat shrink plastic and cable tied to the cct. board. regards in which case go to a model shop and see if they have a 6v nicad pack for a model plane or car. -- To people who know nothing, anything is possible. To people who know too much, it is a sad fact that they know how little is really possible - and how hard it is to achieve it. |

Yes. Does Hertfordshire have one? There used to be one in Hatfield Road, St. Albans but long gone now. I'll have a dig around. regards -- Tim Lamb |

My problem is the alarm system for my daughter's dead 1997 VW Golf GTi contains 5 AA size cells soldered in series. The installed cells are Varta NC 2000. Naturally Varta no longer admit to such an item or any specification. Is a replacement available? The charger forms part of the alarm circuit and I have no idea of it's intelligence level but assume it would never understand NiMh. Any thoughts? Hmm Thats a standard RC nicad size.. I THINK they are still available. The sanyo KR 1000 cells are VERY good indeed.. only 1000mAh but that's all you can get in NiCd - for 2000mAh you need NiMh so if the 2000 is capacity, they ARE NiMh. Clearly says Ni-Cd on the cases. I guess the lower capacity would simply reduce the time an alarm sounder would run. My problem is persuading the engine management system that the alarm is not triggered so they might do. OK a google suggests its actually a 260mAh part - its an NC-2000 260. regards In that case why not get some poundland AAAs, up the charging resistance and try it. Surely VW must have a buyable fix for the problem. a new alarm system I expect Wont necessarily cost that much if its from Brazil etc. |

Must have the slowest site in the world. 6V, 700mAh £9.99 ordered. regards -- Tim Lamb |
