2 Stage vs 3 Stage

Found an interesting article, stating that 3 stage charges can actually harm your battery while it has a load on it, as it reads the load as a lower battery and over charges. (remember you can only get a true voltage/level messurement of a battery when it's at rest with no load.)

Wonder if the charger/converts for RVs are actually smart enough to disconnect the battery and charge it issolated. Thought it might be of interest.

    Just keep your water level up and overcharging will not harm your battery. May make it boil some water out faster than normal but keep it full by checking once a month or so and replenish as needed.

    HHHUUUMMM, make me wonder how my OEM Deka battery lasted 9 1/2 years on my OEM IOTA 55amp converter? I am plugged in 24/365.

    HMMM I just bought a small volt meter at wal mart that had separate test positions for 1 1/2 volt and 9 volt batteries that had a different load built in for each voltage.
