Identical capacity does not mean interchangeable.QV-606090PL and QV-6060110PL both have 5000mAh capacity, but their rate capability and impedance differ completely, so selection follows actual discharge rate requirements. QV-124065 is a polymer lithium-ion battery and not part of the solid-state range, and is described separately from solid-state models.
