Cell size references UM1 – R20 – D
Electrical characteristics
(typical values relative to cells stored for one year or less at + 30°C max.)
Nominal capacity 13.0 Ah
(at 15 mA + 20°C 2.0 V cut off. The capacity restored by the cell varies
according to current drain, temperature and cut off)
Open circuit voltage (at + 20°C) 3.67 V
Nominal voltage (at 2 mA + 20°C) 3.6 V
Pulse capability: Typically up to 4000 mA
(4000 mA/0.1 second pulses, drained every 2 mn at + 20°C from
undischarged cells with 10 µA base current, yield voltage readings above
3.0 V. The readings may vary according to the pulse characteristics, the
temperature, and the cell's previous history. Fitting the cell with a capacitor
may be recommended in severe conditions. Consult Saft)
Maximum recommended continuous current 1800 mA
(to maintain cell heating within safe limits. Battery packs may imply lower
level of maximum current and may request specific thermal protection.
Consult Saft)
Storage (recommended) + 30°C (+ 86°F) max
(for more severe conditions, consult Saft)
Operating temperature range - 60°C/+ 85°C
(Operation above ambient T may lead to reduced capacity and (- 76°F/+ 185°F)
lower voltage readings at the beginning of pulses. Operation with
current continuously above 1 A may restrict upper T range. Consult Saft)
