Ridgid drill/driver kit with 2, 2.0AH batteries

[sternwake]

Did some more Ridgid battery charging while closely watching inline ammeter via wall wart.

While it started at 20.43v unloaded, after refilling 2.23ah into a 4.0ah battery, which measured 18.01 immediately before, it was hitting as much as 2!.37v in absorption.
When it quit charging, checking voltage immediately, 20.71v. Hot wall wart at this point.

If i pulled battery from cradle, while it was stilll accepting 1.09 amps at 21.21v, the pluggeded battery back in, it did nothing for a few seconds, then flashed green light and refused to continue charging.

Different battery, with warmed/hot power supply no load voltage 21.37, 2.0 amps raised voltage to 21.37, and when amps tapered somewhere under 0.23, green light , no more charging. Measure battery V ure Dmm on terminals, 20.73.


While i can, and will use a dc to dc power supply to recharge, faster than 40 watts,, and formerly stated the wall wart is just a dumb power supply, there appears to be a bit more logic involved the charge algorithm, or i am mistaken, again.

I have been trying to attempt to prevent 100% recharges anyway. Seems my dc to dc voltages booater set above 20.499 v causes an orange flashing error LED, the oem wallwart will go as high as 21.38 and amps tPer to nearer zero, ajd it quits/green lights at a higher resting voltage.

If/when i move back i to Van the ridgid batteries are coming, the maKita batteries staying.

If i already had a good PSW inverter and a 12vdc nominal charging surplus, it would be a slightly more difficult choice.

The itty bitty toylike Rdgid comlact jobsite blower is way more Van sized than the Makita blower, but the Makita puts all my other DC fans to shame, and they make one with nearly 2x the volume.

All hail sheer velocity, and finger trigger speed control.
