Charger circuit designed by lm358

Its features:

1. The open circuit voltage is 1.5V;

2. The working temperature range is wide between -20℃~60℃, suitable for use in alpine areas;

3. The capacity of large-current continuous discharge is about 5 times that of acidic zinc-manganese batteries;

4. Its low temperature discharge performance is also very good.

The number of charging times is within 30 times, usually 10-20 times. It requires a special charger and it is extremely easy to lose the charging ability.

Generally, the discharge stops at 1.2v.
