6 AA vs 8 AA

Jake · 2012-07-08T19:48:29+00:00

I have an electronic GPS datalogging device that is designed to be powered through a 9v battery. It runs the battery down in about 2 hours, and because it goes through batteries so quickly, I have been looking for solutions to make it last longerI have had success in replacing the 9v battery with a 6 AA battery holder with attached 9v clip and this powers the device for significantly longer with 2500 mAh rechargeables giving 7.2v.I have seen 8 AA battery clips available, that would give me 9.6v but I am concerned about overvolting and damaging the device. Is the extra 0.6v likely to cause damage?

simple dropper resistor and shunt zener. You are better off with the series diode (as suggested), 0.6V per for silicon, 0.2V for germanium (if you can find one with sufficient current rating).
