Solar Lead Acid Battery Charger

Alexander Said:

what is the dirrerence between maintenance free battery and non maintenance free 12volt?

We Answered:

Non-maintenance free can be topped up with distilled water. Maintenance free can't. That's all the difference there is.

You can charge the non-maintenance free at higher currents as they are not "sealed" so any gas can escape. Your leisure batteries should be used at the "maintenance free" setting as they are designed for slow charge and slow discharge. Car batteries are designed for rapid charge and rapid discharge.
