Following are some tips to be followed while charging Lead Acid Battery: Always keep the battery in a well ventilated space. Do not keep any inflammable liquid like Petrol near the battery. The charger should be plugged in to the AC socket only after it is connected to the battery. Observe the battery while charging.
For example: In a 12V 45Ah Sealed Lead Acid Battery, the capacity is 45 Ah. So, the charging current should be no more than 11.25 Amps (to prevent thermal runaway and battery expiration). Importantly, if you have other equipment connected to the battery during chargning, it also needs to be powered, so you need to add that to your calculations.
Last example, a lead acid battery with a C10 (or C/10) rated capacity of 3000 Ah should be charge or discharge in 10 hours with a current charge or discharge of 300 A. C-rate is an important data for a battery because for most of batteries the energy stored or available depends on the speed of the charge or discharge current.
The charging current for AGM batteries generally should also stay within 0.20C to 0.3C of their capacity. For a 100Ah AGM battery, a charging current should ideally range from 20A to 30A. Higher charging rates can lead to gassing and damage. Manufacturer recommendations play an essential role in determining maximum limits.
The charge current for small lead-acid batteries should be set between 10% and 30% of the rated capacity (30% of a 2Ah battery would be 600mA). Larger batteries, such as those used in the automotive industry, are generally charged at lower current ratings.
