HB lithium rechargeable batteries are environment-friendly
rechargeable batteries that can be reflowed (automatic
mounting by Pb-free soldering) with lead-free solder.
Pb-free refl ow mounting is achieved by a reinforced heat-
resistant structure.
The HB414 features high capacity and a long cycle life
with a wide charge voltage range.
*1. Value measured using AC (Alternating Current) method in the fully charged state.
*2. Counts of charge and discharge repetition that maintains about 50% of the minimum guaranteed capacity
*3. A constant voltage charge is recommended, but due to a limit in charge current, it is necessary to insert a resistor to regulate charge
*4. D.O.D. : Depth of Discharge
