NiMH 12V D Cell Battery Holder

thingiverse

To craft twelve-volt rechargeable dry cell batteries from one point two volts Nickel Metal Hydride D cells, start by bending and placing small copper strips - preferably fairly thick copper is advised - in the grooves for external and internal connections. Ensure you obtain genuine ten-amp-hour D cells, as using twenty-four amp-hour AA cells packaged as D cells may compromise your endeavor. A stack of three trays is sufficient to begin powering a small vehicle. In my practical experience with an eighty-five Toyota Tercel 4-runner, the car's standard charging system effectively replaces the NiMH D cell batteries, rendering them a seamless replacement - albeit users of newer models are advised to exercise caution as their charging procedures may differ significantly.
