Can you put two trickle chargers on a battery?
As long as both charge a 12 V battery then it’s ok – as long as the output of each charger is at 12 volts at all times that it is connected.
Can trickle chargers damage battery?

Can you charge two batteries with a battery tender?
If the nominal battery voltages (i.e. 12V, 8V, 6V) are the same on each battery, and if the batteries are the same lead acid type (flooded, AGM, or Gel Cell), then yes, the Battery Tender® Plus battery charger can be used to charge more than 1 battery simultaneously when those batteries are connected in parallel.
Can I leave a trickle charger on all the time?

Can you charge two 12V batteries at the same time?
An example method of charging batteries in parallel is to use one branch of the parallel circuit to charge each battery with a single charger. Connect the positive output of the charger to the positive terminal of the first battery, and connect that positive terminal to the positive terminal of the second battery.
Will dual batteries hurt my alternator?
The first is if both batteries are low on charge then that would be too much for the alternator, but if only one is low then it would be fine. The second thing is linking the batteries will cause more problems. If you run the inverter from battery in the back then you run them from both.
