Satellite phone Battery

We purchased a cheapie from ebay a couple of years ago for a 9505a and all good.
Contact the seller for an explanation.

I also bought a cheapie on ebay for our 9500, still working ok after about 5 years.

Thanks for the replies, contacted the supplier says it must be a one off and to return it. on the box it says for a 9505 I questioned them on that but they say its the same battery for both I think I will just pay the $155.00 And buy a genuine one. Ouch! Leaving in 10 days time so don't want to be without if they are late sending a replacement.
Thanks again.
Sue.
