4
New cards

purpose of battery electrolyte

charged particles travel through

5
New cards

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

current

6
New cards

cathode is positive or nagative

negative

7
New cards

anode is positive or negative

positive

8
New cards

how do ions self distribute within the electrolyte

like charges repel

9
New cards

what is the key marker of battery health

internal resistance

10
New cards

what effects how fast a battery discharges

load

11
New cards

what is a battery string

batteries connected together

12
New cards

how are batteries wires in order to create higher potential

series circuit

13
New cards

how full should batteries be filled (if required)

not all the way

14
New cards

why do industrial plants have redundant battery chargers

in case one fails

15
New cards

why us a special battery tester needed to verify battery health

to test the inside of the battery

16
New cards

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

the fiber wall is deteriorating

17
New cards

what would cause a battery to be hot when in use

overcharging

18
New cards

hat is release when a chemical battery gets excessively hot

hydrogen gas

19
New cards

what happens to a battery when fluid is too low

it burns

20
New cards

what happens if a battery is filled too high

damage the case of the battery

21
New cards

what causes “green mushrooms” to form on battery terminals

combination of electrolytes plus oxygen

22
New cards

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

cooking liquid out of the battery

23
New cards

why does a battery preform poorly in cold weather

electrolytes freeze up/not allowing ions to travel properly

24
New cards

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

smaller voltage battery wont be able to handle it

25
New cards

what is Ah

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

26
New cards

how are multiple batteries wired together if higher potential is needed

series

27
New cards
28
New cards
