I use 1.5 Volt Energizer Titanium AA's from Sams Club. Only had one problem with the old handsets and Kevin gave me some tips to avoid the issue... (Pull the spring out a little, wire brush the threads and clean the contacts with an eraser at regular intervals.) After that I did that I never had a problem in warm or cold water.
I have the new handsets now, but won't get to use them until April.
Question... Is there a battery tester that can not only check the voltage, but also check them under load to see if they OK to use?

not that I am aware of.. and for that case all testers test for a constant load, which is NOT the case on a device like the HH... a reading with a constant drain around 40ma would show very bad cells, but otherwise would not identify cells that cant deliever on surge.. The voltage monitor on the HH is effective during the dive once you see how it responds over a period of time..
a low resistance short will identify alot of cells as bad that would be perfectly acceptable since all the surges are just pulses not a constant hi current draw..
