Hi Mira.Ibrahim,

 

 

Aside from electrical ratings it is also important to specify the battery chemistry.

 

 

Best regards,

12 В, 9 А, 60 Вт.-???!!!
12 х 9 = 108 Вт
60 / 12 = 5 А

Могу предложить простую схему автоматического зарядного устройства.
Состав: трансформатор 100 вт, 220/18 в, два диода, тиристор, 2 сопротивления, стабилитрон. По мере приближения зарядного напряжения к окончанию, зарядный ток уменьшается и прекращается вовсе. При дальнейшем саморазряде аккумулятора схема вновь включается и дозаряжает аккумулятор до максимума.
