How many said so ... with numbers. Any reply that does not say why - with numbers - is best ignored. Now how many replies exist?
Battery life expectancy is determined by numerous conditions and parameters. For example, a battery left discharged has a reduced life expectancy. If a charger maintains voltage too high or is overcharged, then water can evaporate causing damage to electrodes. That voltage is best adjusted even for temperature. Does your charger do that?
Even 60 years ago, batteries were removed and stored in a well ventilated room with a trickle charger to protect battery life expectancy.
Does not matter what other chargers do. Or what others say they do. Only matters what your charger is doing. For example, what voltage does your charger remain at. Or even better, does it leave the battery alone (no charge or discharge) for most of the day?
