I need about 100 Ah, so Im thinking 2 12v 120 Ah connected in series. Is that in the right range?
The total charge going into the battery is equal to the current multiplied by the time, so multiply the numbers and you'll get a value of about 800—900 mAh.
If you look into our 12 Volt Smart Battery Chargers: Smithsonian Books, 2010. But there is a wide range of chargers with different charge rates on the market - from 2 to 10 amps. The cheapest, crudest chargers use either a constant voltage or constant current and apply that to the batteries until you switch them off.
The light is supposed to turn green when the batteries are fully charged but I have to keep stopping as the batteries are bubbleing and getting hot? The normal consumption is probably only 600w. I have monitored the charging cycle and see no evidence of a 3 step process whereby the regulated voltage is dropped back as the battery approaches full charge.
Is my charger working properly? Thanks, Patrick.
Full Name Should contain only letters, numbers, and ' -. C-rate is equal to battery capacity , which is measured in Ah.
Again, the battery itself claims its capacity is lower than this 1000mAH. Although lithium-ion batteries don't show a memory effect, they do degrade as they get older. From time to time, batteries like this have to be topped up with distilled water not ordinary water to keep the acid at the optimum strength and at a high enough level to cover the plates. If its charger is rated C, it will provide a current of 2.
Start Watching. Or 10 amps total of all three banks? Yes, you're going to be just fine. They do that by heating up and building up pressure inside, which can make them rupture, leak chemicals or gas, and even explode.
Ideally, when almost all the electrolyte of the battery is restored, the supply of current should stop. For reference this is what the CPAP machine says under the electrical version of the manual, and this is where I get a little confused though I have had others tell me they use this battery and inverter with their cpap just fine — but they use a 3 panel 45 watt solar charger which is unfortunately out of my price range.
