Lorn,
My indication of a low battery the fuel flow stopped indicating while in 
flight. After landing, the unit would not power up.
I don't know about the EPI-800, but you reset the VM1000 by holding certain 
buttons and then powering it up. The instructions are in the VM user manual.
Bucky

I have an EPI-800. I replaced the battery about 7 years ago.

Does anyone know what the indications are of the battery needing 
replacement?

On the EPI-800, the tach hours goes to zero with this replacement. I think 
that that is all that is reset. Vision Micro sent me a piece of equipment 
that I could reset the tach hours with. I sent it back when I was finished. 
Does anyone have or know about this piece of equipment?

Lorn
