Jamaican Slang. Always changing, never ordinary! To keep current with Jamaican slang, you need a teenager. So that's what I did for this page. I asked about ten teenagers to brainstorm (no, I didn't actually say brainstorm) with their classmates to come up with the latest expressions.
Most solar panels are 12 volt so use the same equation to find out how many amps the panel makes. 80W = 12V * X Amps 80/12 = 6.67 amps A 50 Amp Hour battery takes 50 hours to charge at 1 amp, 25 hours to charge at 2 amps, and 50/X hours to charge at X amps, just like the discharge calculation above.50/6.67=7.5 hours.ow most CFLs are 120 volts AC and not 12 volts DC like the battery, so I assume you have an inverter to make 120V AC power from the battery. The inverter will not be 100% efficient so the lights will last a little less than the full 23 hours.
RE: How long does a car battery charger take to fully charge a battery? My car broke down on me again and weâve been charging the battery on an external charger for a couple of hours now so we can see if it was the battery or my alternator.eport Abuse. Depenind on what type charger you have Shops use commercial chargers Properly charging an automotive battery goes like this. Charge at a rate of 30 amps for 30 minute intervals and recheck. This can take up to 8 hours to fully recharge a battery.
