how many jumps on protrack B4 batteries die?

[judedre 0]

i think i am getting about 45 jumps average on my pro track before i get the new batt warning then about 5-10 more before i have to replace them just wondering if thats the same for others.?

Sounds about right to me. Especially when you are always changing the break off altitude (freefly or RW).

Or if you look at your speeds every jump that burns them up fast and so does the Jumptrack option.

I think I get a ton more than that on mine. Do you look at it a lot? Leave it in eco mode? Shut it off at the end of the day?

on my skytronic i am getting 110 before battery warning..

if fun were easy it wouldn't be worth having, right?

I got about the same, even when I turn it off at the end of the day. I emailed L and B and they said if I get the same again, send them the protrack for a free service.

There are a lot of factors and I don't think just jump numbers is even the main issue. More like is it in the Economy mode or not and how many days the unit is fully awake.

Also, the display eats up more juice when it's on, so if you're at home looking through the log, you're also burning energy for the thing.

That said, at rate of about 400 jumps per year, looking at the display once or twice per jump day and logging jumps on a weekly basis I get about 6 months between battery changes.

Well, I've always had mine in economy mode and turn it off after I have finished jumping and I am on my second set of batteries that probably haven't lasted 60 jumps without giving the low battery warning.

So, 60 jumps in how many days? Not to be too flip, but I know at least one skydiver that has been jumping for about a year and still doesn't have 40 jumps. ;^)

Are you certain you're always getting fresh batteries?

Sounds like something is wrong.

The batteries that I am using are the ones that came with the pro-track. I bought it around jump 30 or so, back in December 2001 (or sometime close to then). I have since replaced the first set, and am now getting a low battery warning on the second set, some 140 jumps later.

I was still doing student stuff at jump 30 so I didn't turn on or start using the protrack until around jumps 50 - 60.

I had the same problem with my pro-track batteries - the ones that came with it didn't last long. Get some brand spankin new fresh ones, and they'll probably last a lot longer.

I've also noticed different types of betteries last different amounts of time, Newtons 3 months, Panisonic 6 months.
