 Dear lord, those poor batteries. New folks [[electrical:batterycide|kill batteries]] without even knowing it.  It's usually due to [[electrical:12v:psoc|chronic undercharging]] but people will claim they were ripped off, got old batteries, whatever soothes their soul at night.  Dear lord, those poor batteries.

 +Belief that reaching 12.7v means lead batteries are [[electrical:12v:charging|fully charged]];  they certainly are not. Deep-cycled lead batteries typically take hours at Absorption voltage (usually in the 14s) for full charging.  From beginning to end this takes about 5.25 to 6 hours for a battery in good health, and much longer for batteries in poor health.

 Belief that x-thousands of watts in [[electrical:inverter|inverter]] capacity means you have x-thousands of watts to pump into it.  It's not true;  **the inverter could pull x-thousands of watts but that doesn't mean your battery can provide it**, or provide it for long.  And you **still have to stuff those x-thousands of watts back into the battery before sundown**.((plus charging inefficiencies)) Belief that x-thousands of watts in [[electrical:inverter|inverter]] capacity means you have x-thousands of watts to pump into it.  It's not true;  **the inverter could pull x-thousands of watts but that doesn't mean your battery can provide it**, or provide it for long.  And you **still have to stuff those x-thousands of watts back into the battery before sundown**.((plus charging inefficiencies))
