How does a charger prolong battery life, I have a smart charger and my battery is now 21 months old and seems to be in.good condition pa, brand is Emtrac
the battery plates break down faster (sulfation), if kept for longer times in under-charged condition.
these plates break down more slowly, if they are kept in fully-charged condition.

Ideally, yes. Some automatic chargers might not stop charging when the parasitic load is interfering with its measurements. But for practical reasons, no need if you're just topping it off.
I don't trust this charger enough to leave it on indefinitely. I got into this with my eyes wide open.... I know it's not a CTEK, so I won't expect it to behave as such.
While parked waiting at Meralco compound i decided to check the charging voltage of my gs. 14.1V lang with engine on idle. Mababa di ba? Dapat at least 14.5V? napa-order tuloy ako ng smart battery charger sa lazada, yung Foxsur na100 amp model. Di ko nakita agad yung 150 amp e yun sana pero for shipping na kasi nung makita ko. Anyway good naman na for 3sm yung 100 amp. Di pa dumadating. Sana oem.
13.8V is the float-charge for 12V system
4.2V for 3.6V system
42V for 36V
55.2V for 48V...
I had the opportunity to observe more how CTEK works. Once the battery is fully charged, it will stay at a minimum voltage of 12.63 V for a few days.
After a few days, and I don't know how many days, CTEK will "play" charging the battery between 12.63 to 13.18 V. I forgot to measure the time interval.
Once I left the car for about two months and when I started it, it was the first time for me to hear it cranking forever. It was when I didn't use CTEK. It must be noted that I am using a "cheat version" of battery. This is an ordinary battery by Motolite, given free by my friend. I never experienced this with the stock battery, not until it died.
Right after turning on CTEK, voltage will climb slowly, for about a minute, up to 14.05 V.
This is a little lower than the charge coming from the alternator at 14.46 V.
I do not know what is my stock battery, if it's an EFB or AGM. All I know is the brand, Yuasa. It is unfortunate that I wasn't able to observe CTEK on my stock battery, the way I was able to observe it now.
Regular car chargers, including smart chargers, usually have minimum 5 amperes of current. The higher the current, the faster the charging. While, battery maintainers have only 1 ampere, more or less, of current since it is only aimed for maintaining the "charge" at full.

iirc, tatlong beses ko pa lang yata nagamit ang MXS 5.0 i bought last year. one time na na drained ang battery ng kotse and yung tractor ko sa farm, so far ok naman. you will know din if palyado na ang baterya dahil it will remain na lang sa level 3 yung led indicator light niya. i tested charging one spare battery na pinagpalitan.
ang gamit na gamit ko yung freebie na power bank[emoji1787]
