Battery Charger Size Chart (Buyers guide)
What Is C-rate? C-rate is the amount of charge/discharge current relative to batteries rated capacity. For example, if a battery is rated at 120Ah, 1C means 120A. Similarly, 0.5C means 60A, 0.2C means 24A, 0.1C means 12A and so on. Charging C-Rate
Is A Higher Ah Battery Better? Does Higher Ah Equal More Power?
Does a higher Ah battery give more power? Power is measured in watts and watts equals current in amps multipled by battery voltage. This means that higher amp-hours will inevitably mean more power. Examples: 12 V 50Ah battery power = 50 x 12 = 600 watt-hours. 12V 75Ah battery power = 75 x 12 = 900 watt-hours. Deep cycle vs auto …
