Panasonic introduces a new line of NiMH cells that are superior to standard NiMH products in applications with low-rate
charge at high temperatures. Improvements were made in existing Panasonic NiMH cells to the negative plate alloy and,
separator fiber density. A new electrolyte composition was achieved to improve performance.
Superior long-life characteristics can be achieved when combined with appropriate intermittent charge control circuitry. The
intermittent charge consumes 1/30th the electricity compared to trickle charge and more than doubles the expected life of
the NiMH cells compared to NiCd cells that have been trickle charged.
Features
Applications
• Higher capacity in a smaller size and lighter weight than other battery back-up solutions
(Lead-Acid, NiCd)
• Efficient Charging at high temperatures (up to 60°C)
• 8-12 year expected life when used with the proper charge control circuitry
•

NiMH “H” Series Recommended Charge System for back-up power applications
(Applies to HHR60AAAH, HHR210AH, HHR370AH, HHR250SCH & HHR300CH Cylindrical cells)
The optimal charge system for the NiMH “H” Series for
back-up power applications is an intermittent timer
charge. An intermittent timer charge improves charge
efficiency, extends battery life (-vs- trickle charge) and
reduces electricity consumption up to 30% compared
to *trickle charge.
Intermittent Timer Charge: (see diagram) At the
beginning of the charge, an IC timer is started and
charging is activated at a current of 0.1It until the
timer stops and the charge is terminated. When the
batteries self discharge down to a set point (1.3V),
the timer charge is re-activated.
*Trickle charge is not recommended for NiMH
batteries. Please consult Panasonic on any NiMH
applications requiring trickle charge.
• Example of intermittent timer charger system:
Average Charge Current: 0.1ItA
Re-charge Time: 16 hours
Pulse charging can be used

Need specially designed control system
Control System:
dT/dt cut-off; 1 to 2°C/min
-UV cut-off; -UV per cell = 5 to 10 mV
T-control; T=65°C
Rapid charger timer; 2.4h (at 1.25a)
Trickle timer; within 2h

With control system
Battery performance and cycle life are strongly affected by how they are used. In
order to maximize battery safety, please consult Panasonic when determining
charge / discharge specs, warning label contents and unit design.
Note:
[It] was previously expressed as [C]. [It] is an IEC standard expression
for the amount of charge or discharge current and is expressed as:
It(A) = Cn (Ah)/1h.
• [It] is the reference test current in ampres
• [Cn] is the rated capacity of the cell or battery in Ampere-hours.
n = the time base [hours] for which the rated capacity is declared
