![]() Of course the conspiracy theorists said the non-rechargeable battery companies were paying the gadget makers to do this deliberately, but the reality is that it's simply been the growing prevalence of low-dropout linear, and switch-mode, power supplies that allows gadgets to work down to much lower cell voltages. Back in the old days, though, when a lot of electronics gadgets weren't designed to operate to < 1.0 V, the gadget fitted with NiCad rechargeable batteries would malfunction &/or shut off prematurely, and gadget manufacturers would warn customers not to use them, and to use non-rechargeable carbon/alkaline cells. When this is the case, it doesn't matter that NiCad & NiMH rechargeable cells have that lower terminal voltage, they'll still deliver all their energy. Well designed electronics powered by AAA/AA/C/D cells should be designed to work down to well under 1.0 Volts, ideally down to about 0.8V to extract the most energy form the cell - any cell chemistry type. However, every battery chemistry has different characteristics including voltage across a discharge cycle and open-circuit voltage.Įach type of battery chemistry yields quite different characteristics, including terminal voltage.Īt the opposite extreme are Lithium cells in AA & AAA format, but Lithium-based batteries have a 3.x Volt terminal voltage - how do the manufacturers get a 3.x V lithium cell to output 1.5V? They put a tiny switch-mode voltage regulator in the cap! 4PCS NiMH aaa rechargeable batteries in a box, Voltage: 1.2V, Capacity: 550mAh. ![]() 1.2V was a round number close enough to the typical voltage of those three chemistries and thus became the voltage on the label. 1.2V 550mah 6Pack NiMH AAA Batteries for Panasonic Cordless Phones. In conclusion, the 1.2V is only nominal voltage. Ni–Cd cells have a nominal cell potential of 1.2 volts (V).a Ni–Cd cell's terminal voltage only changes a little as it discharges.Ī fully charged cell supplies an average 1.25 V/cell during discharge, declining to about 1.0–1.1 V/cell.the starting voltage of a freshly charged AA NiMH cell in good condition is about 1.4 volts. The open-circuit voltage is 1.4 volts, dropping to 1.2 volts during discharge. So, excerpting the relevant sections of Wikipedia: According to Wikipedia, the following rechargeable battery chemistries have cell voltages of 1.2V:Īt a glance, it would appear that nickel is the common denominator, but this is not the case, as nickel-hydrogen and nickel-zinc have voltages of 1.5V and 1.7V, respectively. Our 24 hours online after-sales service will help you settle your problem until you satisfied.Not all rechargeable batteries have a nominal voltage of 1.2V it is specific to a few chemistries that happen to be popular.
