Battery tender or trickle charger
Which is the best option for keeping batteries charged? My daughter just bought a battery tender for her motorcycle...I had never heard of it. We have a trickle charger that we have used for the truck...

I use a variety of battery charging devices around the homestead. Everything from a wheeled shop charger to wall transformers. My go-to charger for maintenance of stored batteries is a 12V power supply. Since it is not adjustable (could make it so), I connect it to a stored battery and monitor the voltage until it reaches 14 V or so. I then disconnect it and move to the next battery. Currently, I have 3 X 12V auto batteries in storage and in the Winter will add the lawn tractor battery to the pile.
FWIW, I have a Diehard SLA battery connected to my emergency sump pump system. The sump pump controller keeps it charged with current from a wall transformer.
That battery has been in service for 10+ yrs and still does the job if the power fails and we have a large storm.
