A defective battery can hold 12 volts and then some. However, the same defective battery will fail a coil load test. And that is how we test a battery's integrity. Batteries that have vents can release dangerous gases as the battery is charged and if the battery should become overcharged, because it is not holding amperage the liquid acid could vent and spill out of the battery onto metal of a carpeted floor.

The safety issue with the gell batteries is with flying . If acid batteries come in contact with salt water they give off poisonous gas. Since AGM, advanced glass mat,, batteries don't vent, I don't see how they'd be a problem. The law was written before AGM batteries became available. I really think that you have described a dead cell. It's not common but it does happen . I think when you get them tested one battery will read 8 volts or something under 12. I do wish you the best of luck with it.

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
