Easy Charging System For Garrett GTA/GTI/GTP Detectors With 2 x 4 "AA" Battery Clips

I am using the charger I got from Garrett for the Infinium. The pic should pretty well explain the hook-up.

PLEASE! Make sure you have the correct battery polarization!

The 8 batteries are in series giving a fully charged battery pac (8 x 1.5 volts)of 12 volts, equalling the output of the charger. The charger states "ALLOW 8 HOURS FOR FULL CHARGE"

This setup should speed up the process of charging those batteries, and also save some wear and tear on the battery. holders.

Rechargeable NiCads/NiMH produce 1.2 volts per cell not the standard 1.5 volts. Eight rechargeables yields a total of 9.6 volts, considerable lower than the specified 12v. I don't know how critical the lowered voltage is for effective operation of a MD using rechargeables? There are alkaline battery chargers available, with some DIY schematics on the I-net. Alkalines most definitely can be recharged in stark contrast to the myth that they cannot! The crucial thing to recharging alkalines is to monitor temperature and current draw over a specified time. The benefit is getting the full voltage potential from alkalines.
