I use two neptunes. One as an audible and one as a wrist-mounted altimeter --both as logbooks. I bought the first one three years ago at DeLand. It worked the first time and every time after that. I replaced the battery about every 150 jumps, or six months. I mainly used it as an audible and a logbook.
I loved it so much that a year ago I ordered a neptune2. It worked fine, at first, but then it started shutting off when tapped. So I had some freefalls with just my neptune in my helmet. Turns out the battery went bad, fast -- in like a month. So I replaced it with the extra battery that came with it. It too went bad pretty fast. So replaced it again with a battery from Square 3. It went bad in about a month too. So now I went to radioshack and bought a generic bettery, maybe it will work better?
When I talked to alti-2 they said the normal battery life is 3 months.
So I have one good neptune and one not-so-good neptune2. I don't know what they did in-between, but I prefer the older one. Still works great.
