2010 Tomberlin Vanish - charging oddity

[beynon]

My vanish is working fine for light use. I went to use it after it had been sitting for a couple weeks and the battery discharge meter showed (30%) the two lowest bars flashing back and forth, which means it needs to be charged. I put on the charger overnight and in the morning the charger showed solid green (full charge complete). Upon inserting the key I expected to see the battery discharge meter to show the 100% bar. Instead it's still alternate flashing the two lowest bars that means 30%.

The batteries are < 2 yrs old and have been watered each time they are charged.

Any suggestions what this means and how to diagnose?

Thanks,
Mike.

Gauges in those things are not very good. Try a hard reset- (Disconnnect battery power, wait a couple of minutes, then reconnect) , Or disconnect the wires, from the back of the gauge

After disconnecting and reconnecting the batteries the gauge showed it was full. Then a few minutes later the discharge meter showed (30%, the two lowest bars flashing back and forth) again. Sigh.

Other than just ignoring it, is there an aftermarket meter that I could install instead?

Thanks,
Mike.

Mike, I prefer the analog gauges. The needles do jump a bit but it seems easier to follow what's happening. Based on the ages of the vanishes, your batteries are probably near end of life (assuming you've checked them for water levels as low water would also do as you've described-appear fully charged but not last very long at all)
