In the days of NiCd and NiMH batteries, a backup was necessary on longer trips. However, with a Li Ion battery, the need is not so great. The lithium batteries do not self discharge at an appreciable rate. The M72 also has a 2AH battery and that will work full time for quite a while. As long as you don't intend on monitoring channels continuously on a trip, you should be fine. I used my M1V for several minutes a day checking weather on an almost two week trip and barely drained the battery. The M72 has about 25% more battery capacity than the M1V. I also figure that if I will be in a situation where I will definitely need a backup, I can use an SLA + charger or charge off my pump battery. A solar PV panel is also a long-term option, though a second VHF battery is cheaper. The PV panel allows charging camera and other gadgets too.
