Charge a 12V 90Ah led acid battery using 12V 20A SMPS
How can someone make this kind of SMPS to be able charging a lead-acid battery? The following setup approaches the recommended settings for a 2-stage Lead-Acid Charger: Use a small-value and high-power resistance; the use of 2…4 headlight lamps in parallel (each 12V 50~60W) can create an inexpensive power resistor.
When a lithium battery is full, trying to charge it more will cause damage. Conversely, in a car the "12 V" lead-acid battery is usually just charged with a fixed voltage of about 13.6 V. At that voltage it will take a small amount of charge current even when full, but unlike with a lithium battery, this does the lead-acid battery no harm.

$begingroup$ @HoussemOuni I think lead-acid batteries are less commonly used with BMSes because the batteries are more robust. E.g. slight overcharge is no problem (it is converted to heat) and the battery doesn''t explode. Also why they don''t come with balance ports - you just trickle-charge for a while and then you know all the …

The battery provides 0.1 amps for 20 hours, giving the 2 ampere-hour rating. The curve marked "0.6CA" would have the battery subjected to a constant current load of 0.6 * 2 or 1.2 amps, and the battery provides this current for about one hour, so at this rate the battery provides 1.2 ampere-hours (the data sheet table says 1.25).
