Caracteristici tehnice:
Tensiune: 12 V
Capacitate: 20 Ah
Dimensiuni:

– Inaltimea totala (cu terminale): 167 mm
Greutate: 6.2 kg
Pentru o descarcare in siguranta si pentru a prelungi durata de viata a bateriei, tensiunea finala de descarcare nu trebuie sa scada sub valorile urmatoare:
– la un curent de descarcare cu o valoare de pana la 0.1 * capacitatea bateriei (A): minim 1.75 V
– la un curent de descarcare cu o valoare intre la (0.11 … 0.2) * capacitatea bateriei (A): minim 1.70 V
– la un curent de descarcare cu o valoare intre la (0.21 … 0.3) * capacitatea bateriei (A): minim 1.67 V
– la un curent de descarcare cu o valoare intre la (0.31 … 1) * capacitatea bateriei (A): minim 1.60 V
– la un curent de descarcare cu o valoare peste 1.1 * capacitatea bateriei (A): minim 1.3 V
De asemenea, o incarcare corecta va prelungi durata de viata a bateriei. Este necesar un control precis al tensiunii de incarcare, astfel:
– in asteptare si tampon (floating): 2.25 si 2.3 V/element, la o temperatura de 25 C
– in functionare ciclica: 2.35 si 2.45 V/element, la o temperatura de 25 C
Curentul initial recomandat este de maxim 0.3 * capacitatea bateriei (A).
Valoarea tensiunii de incarcare trebuie compensata cu temperatura: trebuie crescuta usor in cazul temperaturilor scazute (iarna) si scazuta in cazul temperaturilor crescute (vara) ( +/- 3 mV/ grad Celsius/ element in modul standby sau +/- 4 mV/ grad Celsius/ element in modul de operare ciclica).
Rezistenta interna (acumulator complet incarcat, la o temperatura de 25 C): 12 mOhm
Efectul temperaturii asupra capacitatii bateriei:
– la + 40 C: 102%
– la + 25 C: 100%
– la 0 C: 85%
– la -15 C: 62%
Autodescarcare (la 25 C)
– capacitatea dupa 3 luni de depozitare: 91%
– capacitatea dupa 6 luni de depozitare: 82%
– capacitatea dupa 9 luni de depozitare: 64%
Ambalare: 4 buc./carton
