Universal No Power Aa Dummy Fake Battery for Shell Placeholder Cylinder Conductor Replace for Lithium Iron Phosphate Bat

I got these mainly so I can use 3.2V LiFePO4 AA sized cells in some devices that are made to use 2 or 4 AA batteries. One of these dummies paired with a 3.2V cell is equivalent to two alkaline 1.5V cells. The advantage over NiMH is that the LiFePO4 cells (paired with a dummy) have a voltage level that is a close match with fresh alkaline batteries. The lower voltage level of NiMH batteries can confuse some devices. The advantage over alkalines is rechargeablility and far less likely occurrence of leaking caustic chemicals. These dummy cells fit my devices, appear to be durable, and were fairly priced (40 cents per dummy, shipped). It took a while to get them, but I wasn't in any hurry and the delivery estimate was accurate (the tracking was useless though). Read more

Measured 4 to 5 milliohms resistance with 2 amps of current through these AA dummies. I measured 4 and they were consistently in the range above. Takes longer to be delivered but great price if you can wait. I would buy again. Read more
