I've used my charger on lead acid, (( check with distilled water ), and gell, and maintenance free and it's still doing the job. I have had to replace the charger, though . to charge your batteries you must have 24 volts and about 20 amps. Most chargers begin at 30 some amps then drop to 15 and then finally 3 or 2 before they stop charging. Always at 26 to 24 volts. most electric multimeters can test them. the pi symbol is what I've never seen. It must mean something . maybe 1 battery has a dead cell? Best wishes , John s .

My chair is real old also 7 years plus and trying to get a new one because my back-up chair is shot and this one is beginning to develop problems also.

After about 4 miles, my chair has 2 out of 5 bars left of power. Then really gets bad even on a small ramp. Chair stops, charge bar meter flashes and I have to turn it off and on. The last 3 weeks or so, after a few miles, the charge meter on the joystick flahes the Pi sign, TT one wavy cross on top. The chair repair shop, nor Invacare, can figure out the flashing Pi sign. Neither have ever seen it before. My chair is old and I'm just starting the new chair prosses. But is there anything that an old chair can do to cause batteries to go out fast. Or draw to much power? Just called to try and get the battering replaced. Greg
