Reparing a "La Crosse BC-700"

[hiuintahs]

........During charging, the battery has overheated. Thermal protection did not work. The hot battery melted the bc-900 charger housing. Is it possible to buy a small housing for this device. in a la croose company or in another. For aesthetic reasons. I did not notice any damage on the PCB G216D1V09 board

Throw away electronics world. You won't be able to purchase just the chassis. The least expensive you could do is to buy someone else's non working unit but in good cosmetic condition. I see there is a "for parts or not working" sale on ebay. Price seems kind of high for a non-working unit, but you could make an offer. Also you could put in a search on ebay for what you are looking and allow email notifications. It might take some time though. Probably best just to get a new charger.
