Charge your battery in a well-ventilated location. Select a location like a garage or large shed. Open a door or window if you can. Good ventilation is important because, during the charging process, a mixture of gases builds up in your battery, and if the battery is overcharged or shorts out, these gases may vent out of the battery.
As a reminder, these are the 3 stages or modes applicable for normal charging of lead acid batteries: Bulk mode: Charging current is limited up to a "safe" value, while the battery voltage increases. It is a constant current (CC) mode.

Charging Current vs arging Time Shown is the current needed to charge a battery from 0% to 90% state of charge in a given time. Or time required to change a battery from 0% to 90% state of charge at a given current. For example, to charge an 8G8D (curve H) to 90% in 3.5 hours, 100 amperes are required; at 35 amperes, it would take 10 hours Hours
There are two main methods for determining the state of charge for lead-acid batteries: Terminal Voltage - The open circuit voltage (no current flowing) of a fully charged cell depends on its type but will be 2.1V to 2.3V (12.6V to 13.8V for a 12V battery).

The charging rate depends very much on the battery''s chemistry – Lead-acid, Ni-Cad, NiMh, Lithium-ion, etc. The maximum charge rate for wet cell lead acid battery is about 10% To 15% of the amp hour rating and 30% for Lithium-ion batteries. Suppose you have 12v 120 Ah battery (assuming it''s lead-acid) should be charged at 12 to 24 Amps max.
The maximum charging current for a lead-acid battery is 50% and 30%. But recharging your battery at this much high amps will decrease the battery life cycles. The maximum charging current for lithium-ion battery. Lithium batteries can handle current up to 100% of their capacity. For instant, 100 amps for a 100Ah battery.
