Triumph 2 & HPT435 BT Pairing

Nate, I got a feeling that you are right about the battery. The ground is frozen solid up here and 20 degrees is not the wind chill reading and I do not pay a lot of attention to making sure the battery is fully charged, because the battery is so big. I got it charging right now. I will let you know. Phil
Just a side note, I have had my LS "lockup", (due to software and sequence/camera issues).
I can hold the on/off button down, (forced shutdown), and restart it.
It ALWAYS has reconnected to base radio, without a hitch. (no need to return to, or restart base).
Move radio closer to base, (I wish it had long range bluetooth!)
And, get a nice biG well charged battery on base. Marine, or sla.
My choice is 50 ah sla.
As Matt says, if it drops below some predescribed voltage, (9 volts, in this case) and, it takes you 45 min to travel back to the base, then during this "break" or time of no load, on the battery, it can "recouperate". So, battery voltage goes back up to say 10.5 volts. Now, you restart the base/radio combo. And, it can run another hour, before voltage drops again.
I recomend SLA (sealed lead acid) batteries, or, if in a hurry, a large marine battery. (cannot wait for battery from online source).
Stanley makes a 2 amp charger, that can run indefinitely. It will take care of your base battery.
I should not have said car battery. I actually use the battery that came with my 35 watt radio Javad system. I would just charge it now and then for a hour or two, so I think I was not charging it enough. I will find out tomorrow in the field. I appreciate the help from you guys. Sometimes I am not thinking too clear and overlooking the most simple and obvious.
Nate, it was either the terminal connection not quite tight or the battery. I bought a charger like you have and it said battery was fully charged and not dead, but it went out after a hour or so, but I had another old battery and that one worked. I ordered another new battery so I will have 3 and probably the first battery is done for. Thanks Phil
Phil, it's a good practice to keep a ESV (Expanded Scale Voltmeter) in your work wagon.
After workin, but before unhooking the power to the radio, just look at battery voltage, (while it's still under load).
This keeps you "in touch" with this general problem, which, in fact never fully goes away.
I get a new base radio battery, every 1 to 3 yrs.
Base batteries are like a cow: useful, necessary, and unpredictable.
But, the milk is good!
