Do you use battery charger and which one?

[sinto607276]

I use the datatool make of the optimal,
I've always used it, never to charge, just to trickle and keep the battery in top notch condition, I've never had to replace any battery that I've had connected to either this or the optimate version.
And yes the battery charges as you use it, as previously stated, but I've never just ran a battery without using an optimate or the datatool one, so can only say my experience
