Sealed alkaline nucleotidase (NiCd) and Nickel-metallgidridnye (NiMH) batteries are finding increasing application not only in industrial devices but also in home appliances, replacing batteries size AA and AAA. But these batteries, like any other, eventually “emptied” and require charging. To recharge, as recommended by the instructions for use and marking of the batteries themselves, through them must pass through the current ICT = 0.1 mA from the numerical value of the nominal capacity C for 12 — 16 hours.
But what if a suitable current or “smart” electronic charger and a simple transformerless available charge current differs from the value of batteries? To estimate the charging time is definitely unlikely to succeed. And if you define it by eye, when incomplete charging capabilities of the batteries will be limited but if excessive shortens the life and even the possibility of their explosion!
So that when you use not native charger, in which the charging current Iz is different from the standard (0,1), we offer a charging time t s to determine using a special formula. At its conclusion based on the following main points:
