It's a joke. The thing is a 1.5 amp trickle charger. Something with
that low an output doesn't need 3 stages.

You can leave a 12 volt car battery hooked up to an "always on" 1.5
amp charger indefinitely without causing any harm. It will maintain a
charged car battery, but it probably couldn't charge a dead one.

Walmart sells an excellent name-brand (schumacher) 3 stage smart
charger that has custom settings for flooded, Gel and AGM batteries.
25 amps max. Less than $50.

If it is over 13.3v 1.5a will ruin a battery, You dont know how high
or or what voltage the charger puts out, it may be the other case
where it never puts out enough. Until something is tested with a meter
you wont know.
