For example, a 12V lead-acid deep cycle battery at 100% capacity will have a voltage of around 12.7V, while a battery at 50% capacity will have a voltage of around 12.2V. By measuring the voltage of the battery and comparing it to the chart, you can estimate the remaining capacity of the battery.
The weight of a 120Ah battery depends upon the battery voltage and the technology used to produce the battery. For instance, the weight of a 12V 120Ah dry battery is around 33.5kg, whereas the weight of the 12V 120Ah lithium-ion battery is 10 kg. Whereas the weight of a 24V 120Ah day battery is 103 kg.
The maximum permissible charging current of a 12V, 120Ah dry battery is 30A. But the recommended charging current is 10 to 18A. How long does it to charge a 120Ah battery? A 100% discharge 120Ah battery can take up to 8 hours to 80% charge at a Charging current of 12 A.
Charging current for 120Ah Battery = 120 Ah x (10 ÷ 100) = 12 Amperes. But due to some losses, we may take 12-14 Amperes for batteries charging purpose instead of 12 Amps. Related Posts Battery Charging Time: Suppose we took 13 Amp for charging purpose, then, Charging time for 120Ah battery = 120 ÷ 13 = 9.23 Hrs. But this was an ideal case…
The tentative dimension of a 12 V 120Ah battery is 407mm (L) x 177mm (W) x 225mm (H), whereas the dimension of a 150Ah battery is 556mm (L) x 130mm (W) x 296mm (H). If we compare a 120Ah battery with a 200Ah battery. We will find that a 120Ah battery stores a lesser charge than a 200Ah battery of an identical terminal voltage [that is 12V].
It can supply 1.5 V, but I don't see any information about the current (in A) or the power (in W). Where can I find this information? You should look in the datasheet of that AA battery and check the discharge curves. That gives you an indication. Note that the highest discharge current that is mentioned is 1000 mA = 1 A.
Battery Charging Time: Suppose we took 13 Amp for charging purpose, then, Charging time for 120Ah battery = 120 ÷ 13 = 9.23 Hrs. But this was an ideal case… Practically, it has been noted that 40% of losses occurs in case of battery charging. Then 120 x (40 ÷ 100) = 48 …… (120Ah x 40% of losses) Therefore, 120 + 48 = 168 Ah ( 120 Ah + Losses)
For example, a 12V lead-acid deep cycle battery at 100% capacity will have a voltage of around 12.7V, while a battery at 50% capacity will have a voltage of around 12.2V. By measuring the voltage of the battery and comparing it to the chart, you can estimate the remaining capacity of the battery.

According to Battery University, a respected online resource, a conventional lead-acid battery should be charged at a rate of 10% of its 20-hour capacity.This means if your battery has a capacity of 50Ah, you should aim for a 5A charging current. But what about deep-cycle lead-acid batteries?
How much car battery mAh capacity does your standard automotive have? First, you need to know the size of your battery. It would be best if you also considered what it would take for your vehicle''s demands and needs.
