lead. They arered, positive (+)and black, negative (-). Since the charger cannot detect
the difference betweenthe internal resistances of the battery pack, cable resistance
and connector transferresistance, the firstrequirement if thecharger to workproperly
is that thecharge lead shouldbe of adequateconductor cross-section. And also high-
quality connectors (normallygold-contact type) mustbe fitted toboth ends.
Refer to theinformation provided bythe battery manufactureregarding charging
methods, and verifythe recommended chargecurrent and chargetime. Especially for
Lithium batteries, youhave to followthe charge instructionprovided by the
manufacturer strictly.
Do not attemptto disassemble thebattery pack arbitrarily.
You have to pay attention to verifythe capacity and the voltage of the Lithium battery
pack. It maybe composed ofparallel and seriesconnection mixed. In parallel link the
capacity of thebattery pack ismultiplied by thenumber of cellsbut the voltage remains
the same. Thatkind of voltageimbalance causes a fire or explosion during charge
process. We recommendyou compose theLithium batter pack in series only.
Discharge
The typical purposeof discharge is to determine the residual capacity of the battery,or
to lower thevoltage of battery to a defined level. When you discharge the battery you
also have topay attention onthe process same as charging. To avoid thebattery
becoming deep-charged, setthe final discharge voltage correctly.Lithium batteries
should not bedeep-charged to lowerthan the minimumvoltage, as this leads to a rapid
loss of capacityor a total failure. Generally,you do notneed to dischargeLithium
battery voluntarily.
Some rechargeable batteriesare said to have a memory effect. If theyare partly used
and recharged beforethe whole charge is drawn out, they remember this and next
time will onlyuse that partof their capacity. This isa memory effect NiCd and NiMH
batteries are saidto suffer frommemory effect. They prefer complete cycles; fully
charge then useuntil empty,do not rechargebefore storage-allow themto self-
discharge during storage.NiMH batteries have less memory effectthan NiCd.
The Lithium batteryprefers a partial rather than a full discharge. Frequent full
discharges should beavoided if possible. Instead, charge the battery more often or use
a larger battery.
The brand-new NiCdbattery pack ispartially useful with its capacity until it has been
subjected to 10or more charge cycles in any case. The cyclicprocess of chargeand
discharge will leadto optimize thecapacity of battery pack.
Those warning and safely notes are particularly important.
Please follow theinstructions for amaximum safely; otherwise
the charger andthe battery canbe damaged violently. And also
it can cause a fireto injure a human body or to lose the property.
