There is, of course, another way, and that is to use your DPV on a regular basis, keep your batteries charged/maintained, and pay attention to how she's running in the water. You basically know how long your battery should last, so go ahead and replace it/them at the start of the season you know it's going to go.
It's worked for me for the last 12 years.
