No-nonsense Modes
There are total 6 operation modes ('Break_in' for NiMH/NiCd/Eneloop batteries only, 'Storage' for Li-Chemistry batteries only).
Charge the battery at the selected rate. Suitable for frequently used batteries. Discharge the batteries at the selected rate. Suitable for batteries stored for more than two weeks but less than 3 months or the batteries showing poor performance. This mode can also determine the battery capacity for battery matching. Battery forming is a charge-discharge-charge cycle which forces a full charge into the new batteries and those stored for more than 3 months at a very low rate to activate the batteries. Performs charge-dicharge cycle for up to 99 times. Cycle mode can remove memory effect of rechargeable batteries. Charge/Discharge a lithium battery to a voltage which is, theoretically, better for storing a long time while maintaining the maximum of its lifespan.
