+GreedyRogue Posted April 4, 2011 Share Posted April 4, 2011 I just bought a Garmin gps V for a decent price. My question is regarding battery life. I used a set of alkaline batteries and the battery life was great. I put in a pair of fully charged nimh's, and the unit said low battery and shut off after 10-15 minutes. I tested the batteries at home and they all register over 1.19v. I made sure that the battery type was set to nimh, even tried the other three options and the unit still powers off in under 2 minutes. I have read others having success with the rechargeables back when they first came out. Any idea why it loves the alkalines but hates nimh? I can't afford to get a better unit right now so I need to get this one up and running. Any suggestions would be appreciated. Quote Link to comment
+S&G.Davison Posted April 4, 2011 Share Posted April 4, 2011 There is an option in setup to change battery type to NiMH.. This sets the unit to accept the lower voltage of NiMH without shutting down like your seeing Quote Link to comment
+GreedyRogue Posted April 4, 2011 Author Share Posted April 4, 2011 As I posted above, I already tried setting to to nimh, and still same issue. I also tried setting it to alkaline, nicad, and lithium and same issue. Quote Link to comment
+phantom4099 Posted April 9, 2011 Share Posted April 9, 2011 NiMh nominal voltage is 1.20 volts, when fully charged they should be higher than that. The different battery settings on the V only changes the way the battery level is displayed and won't effect the running time of the GPSr if it is set to the wrong battery type. Wyatt W.
