FlashTrax battery question

[Joseph Tainter]

I think some pdml*ists have this. Do the instructions say to run the 
battery all the way down before recharging?

Some rechargeable batteries need to be fully discharged before 
recharging. If they are recharged with, say, 1/4 of a charge left, that 
will become the new "bottom." The next time, the battery will only 
charge to that point. This can be reversed, but it is a nuisance.

Let's say your FlashTrax has only 1/4 charge left. What do you do? It 
may not last for a day's shooting. OTOH, if you recharge it, the battery 
develops this memory problem. It seems to me that replaceable batteries 
would be better.

Anyway, I am considering the FlashTrax and wonder is someone can answer 
this.

Thanks,

Joe
