i youtubers jeff cote here

with another session of ask pys we've

got a fellow boater

asking a question about batteries

trays and battery boxes so the question

is

jeff i've watched several of your pys

youtube videos thank you

in which you detail the need for a

battery either tray or box depending

also about you mentioned about properly

securing the box and methods can you

tell a little bit more about this

especially in regards to spilling

battery asset

okay good question

so this is probably one of the most dis

concerning um

faux pas big word here

that installers or do-it-yourselves

make on boats and that is installing

batteries

especially flooded lead acid batteries

so batteries that could leak

right either they're going to leak

because they're being overcharged

they're going to leak because as they

age when we charge them

they sort of basically vent electrolyte

through the vent caps

and or the crack right battery i've seen

batteries crack

because of maybe cold temperature

when you have a flooded lead acid

battery it's absolutely

essential okay and you can forego this

advice

but you will suffer the consequences

it's just a matter of matter of time

you want to make sure that the battery

is in a liquid

tight container unfortunately a lot of

these battery boxes that we buy

from battery suppliers don't come with a

manual there are no instructions

you're simply buying a battery box you

get this battery box and you're thinking

oh

must be like ikea they must have given

me everything i need to install this

battery box

no of course not because it's a boat and

it's not easy

you want easy i tell this seller rent a

hotel room

go on a trip all-inclusive boating is

not easy

so you got a battery box but a lot of

boaters are seeing those battery boxes

and they have no idea of how to stop it

from moving

so what do they do they drill holes from

within

right and they defeat the very purpose

of buying the box but they don't know

that

because the battery box doesn't come

with a manual so it's not their fault

they just haven't been informed so this

is me sharing with you the pain that

i've seen

other boaters go through so when you buy

a battery box you've got to make sure

that it's absolutely

liquid type if you have a flood lead

acid battery

so you're going to actually hold the

battery from the outside and

you're going to stop that battery box

from moving you're going to make sure it

doesn't go up and down

but you cannot fasten it from within the

battery box because that compromises the

battery box so that's the first thing

and you do that with flooded lead acid

batteries now what about seal

valve regulated lead acid batteries

five big words seal valve regulated svr

and what are the examples of that agm

absorb glass mat or gel

agm and gel batteries do not have the

liquid electrolyte

the electrical light is either in a gel

format or an absorbed glass mat

those batteries can't leak you could

literally

saw them in half you could drill a hole

in them doesn't matter there's no

going to be no leaking of electrolyte

question is should i have a battery box

with those batteries too

well if you can fit a battery box it's a

good idea because what you're doing is

you're putting

a top a lid on top now the battery will

never leak and you could actually

screw inside because it doesn't matter

there's never going to be any

electrolyte sloshing in there

but a battery box is good because it

keeps all those positive terminals on

top of the battery protected from

an accidental short and that's something

that we as boaters always have to worry

about

is that nobody ever gets complacent and

sees a positive and negative post on a

battery

and for inadvertently puts a metal like

a it could be a prawn trap it could be a

tool it could be

anything that's metallic and conductive

on top of a battery

so that would be a good reason why you

would put a battery box with an agm

battery

or a gel battery now

in some instances battery box can't fit

in and so if a battery box can fit in

and it's an agm battery then make sure

you use protective boots on top of the

positive post and also even on top of

the negative posts

because yes if half of it is there then

you shouldn't worry but might as well

cover both the negative and the positive

posts

so that you can never have an accidental

short so battery boxes are a good idea

if you can fit them in

you have to have one if it's lead acid

battery flooded

if it's not a flooded lead acid and it's

a seal valve regulated battery either

gel or agm

then you can have it in a box which is

preferable it doesn't have to be liquid

proof

it's okay but it's really nice to have a

lid because over time

people tend to forget the batteries are

good

but also very dangerous so great

question

and if you've got battery boxes on your

boat

look and if you're asking yourself how

is this battery box magically held in

place

unfortunately someone probably actually

fastened it from within

and you'll have to replace the battery

box and do it all over again

remember rule number one it's never easy
