purpose of battery electrolyte

charged particles travel through

what can pass through fibrous paper (the dividing layer of battery cell)

current

cathode is positive or nagative

negative

anode is positive or negative

positive

how do ions self distribute within the electrolyte

like charges repel

what is the key marker of battery health

internal resistance

what effects how fast a battery discharges

load

what is a battery string

batteries connected together

how are batteries wires in order to create higher potential

series circuit

how full should batteries be filled (if required)

not all the way

why do industrial plants have redundant battery chargers

in case one fails

why us a special battery tester needed to verify battery health

to test the inside of the battery

what would cause a battery to be hot when not in service

the fiber wall is deteriorating

what would cause a battery to be hot when in use

overcharging

hat is release when a chemical battery gets excessively hot

hydrogen gas

what happens to a battery when fluid is too low

it burns

what happens if a battery is filled too high

damage the case of the battery

what causes “green mushrooms” to form on battery terminals

combination of electrolytes plus oxygen

what can be a concern d a bettery is charges too fast

cooking liquid out of the battery

why does a battery preform poorly in cold weather

electrolytes freeze up/not allowing ions to travel properly

what is a concern if multiple batteries of different sizes are connected together

smaller voltage battery wont be able to handle it

what is Ah

amp per hour/ 300 ah = 300 amps in an hour

how are multiple batteries wired together if higher potential is needed

series

how re multiple batteries wired together if longer run time is needed
