Batareyaning sig'imi batareyaning tashqi tomonidagi yorlig'iga, zaryadlash oqimi esa zaryadlovchida belgilangan kirish oqimiga bog'liq.
1. Zaryadlash oqimi batareya quvvatining 5 foizidan kam yoki teng bo'lganda:
Charging time (hours) = battery capacity (mAH) 1.6 ÷ charging current (mA)
2. Zaryadlash oqimi batareya quvvatining 5 foizidan ko'p va 10 foizdan kam yoki teng bo'lsa:
Charging time (hours) = battery capacity (mAH) 1.5 ÷ charging current (mA)
3. Zaryadlash oqimi batareya quvvatining 10 foizidan ko'p va 15 foizdan kam yoki teng bo'lsa:
Charging time (hours) = battery capacity (mAH) 1.3 ÷ charging current (mA)
4. Zaryadlash oqimi akkumulyator quvvatining 15 foizidan ko'p va 20 foizdan kam yoki teng bo'lsa:
Charging time (hours) = battery capacity (mAH) 1.2 ÷ charging current (mA)
5. Zaryadlash oqimi akkumulyator quvvatining 20 foizidan ko'p bo'lsa:
Charging time (hours) = battery capacity (mAH) 1.1 ÷ charging current (mA)
