Charge (solid lines) and discharge (dashed lines) curves at different fixed current densities of 0.5, 2, 4 and 7 mA cm-2 for (a) A-TNO and (b) V-TNO electrodes are shown.

And, NiMH batteries have a higher self-discharge rate than lithium-ion batteries, which means they can lose a more significant portion of their stored energy when not in use.

Dallas Semiconductor introduces the DS2715, a versatile NiMH, battery-pack charge controller. The DS2715 can be optimized for a variety of charging scenarios for either removable or embedded battery ...
