-Never attempt to disassemble a battery pack.

-It is imperative that you pay attention to the capacity and the voltage of the Lithium 

battery pack. Lithium battery packs may be composed of parallel and series connection 

cells.  Cells  in  series  multiply  the  voltage  of  each  cell  by  the  number  of  cells.  Cells  in 

parallel multiply the capacity of the cell. Most Lithium packs will have information stamped 

on the outside of the package. It is your responsibility to understand the configuration of 

your battery packs.

Discharge

Discharging  a  battery  pack  is  used  to  determine  the  residual  capacity  of  the  battery, 

or to lower the voltage of battery to a defined long storage level. When you discharge 

a  battery pack you should pay close attention to the voltage levels to avoid the battery 

becoming deep-discharged. Lithium batteries should never be deep-discharged to lower 

than the minimum manufacturers recommended voltage. Generally, you do not need to 

discharge Lithium battery packs. 

-Some NiCd and NiMH batteries are said to have a memory effect. If they are partly used 

and recharged before the whole charge is drawn out, they ‘remember’ this and next time 
will only use that part of their capacity. 

BLACKMAX

 offers a Charge/Discharge cycling 

algorithm to assist in maximizing the life of your NiCd and NiMH battery packs.

-A new NiCd battery pack requires several charge/discharge operations to reach it’s full 

capacity. The cyclic process of charging  and discharging will optimize the capacity of 

battery pack. 

- Lithium battery chemistry is better suited to partial rather than a full discharge. Frequent 

full discharges should be avoided if possible. Instead, charge the battery more often or 

use a larger battery.

Warnings and safety notes are important. To avoid 

injury, loss of property or damage to the charger 

please follow the instructions.
