Hi everyone,

Just bought a Naki Solar Pak, this accesory is from 1993 and seems that the rechargeable battery is dead.
Did anyone already open one of these? It says it has 4 NI-CD 500mAh on the sticker so want to replace them with new 2450mAh Nikel-Metal batteries, but can't find how to open it without breacking it =/
Any help?
