Page 8: How To Confirm Charging Current
Expert said to suffer from memory effect. They prefer complete cycles; fully charge then use until empty, do not recharge before storage-allow them to self-discharge during storage. NiMH batteries have less memory effect than NiCd. • The Lithium battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided if possible.
Page 9: Charge Mode Selection
LD300 charging current would be 2000*5=10000mA; therefore, the maximum charging current is 10A. For lithium battery, if it can not confirm the supported charging C value, please set the Program settings charging current below 1C for the sake of 15.8 A Battery type safety.
