battery knowledge
Term | Definition |
---|---|
who invented the battery | james volta 1800s |
first battery was made of | zinc, saltwater and silver |
advantage | portable,reliable |
disadvantages | short life, energy use small and expecsive |
how batterys work | chemical reaction inside frees up electrons that travels from negative(anode) to positive(cathode) |
postive is | cathode |
negative is | anode |
inverters | dc to ac |
bigger battery means | more current (amps) |
hydro-meter | checks a sealed battery condition of electrolyte |
wet cell info | secoundary, chargeable, 2v per cell |
dry cell info | primary, nonchargeable, 1.5v per cell 1.28v means its good on a hydro meter |
battery | group of cells |
types of batterys | lead-acid, nickel-cadmium, lithium, nickel-metal, alkaline-zinc, zinc-carbon |
battery maitntenance | 1.keep dirt out of battery 2.keep it charged 3.add water when needed 4.use distilled water if needed before chargeing 5.use tickle charger for long term storage 6.clean terminals with wire brush and bakeing soda 7.wear proper PPE |
batterys in series | produce an increase of voltage |
batterys in parallel | increase life share the load same, voltage |
how to charge a dead car battery | (dead)+, to (good)+, (good)-, FRAME! |
ion | charged partical |
batterys dead when | no change in potential |
bigger batterys mean | more current, lasts longer |
chargeing | reverse currents |
