Storing the hp50G

[zx_spectrum]

recently i got my self a new hp50G.
i am not intending to use this it right now as i really cannot apart with my beloved 48G.
so i need to store it to be used later when my 48G dies eventually.

1- What is the best way to store the 50G?

2- i have heard people saying that it may be better to store the unit with the keyboard facing upward so that when the internal battery (memory back-up battery) leaks, the acid would seep out through the AAA-battery door and not damage the internal PCB. so why not to store it without the battery all together, hence why not to remove the memory-back up battery before storing the unit since it will eventually die and leak and the machine would remain without a battery anyway ????
