have you ever asked yourself the question which is more cost effective petrol or battery well
we're going to answer it right now welcome back to machinery nation in a previous video we tested to
see how much it would cost to charge a 5 amp hour battery and it cost 12 pence so we thought why
don't we put 12 pence worth of fuel into a petrol strimmer and see which one lasts longer right
let's work out how much petrol we need and crack on with the test all right carrot crunchers i'm
norman and today i'm going to show you how we work out 12 pence worth of fuel for this trimmer yeah i
am i am oh at the moment fuel is 1 pound 80 liter yeah it is blooming expensive in it i know never
you thought we'd see like in my lifetime anyway if we divide that by a thousand which is how many mil
there is in a liter you come out with 0.0018 that's right that's how many ever pence that
is per mil well we then go and times that by 67 that's right 67 you'll get hang on we'll get 0.1
pence ah i know my brain's hurting now but that's how we get we need 67 mil a fuel to go into this
trimmer to be the same equal amount of money in each machine right back to james right so norman's
gonna mix the fuel for me and then he's gonna come out and fill up this trimmer with 67 mil of fuel
james has asked me if i get my hand as well to do this i'm going to suck out 67 mil of fool out
of this and take it out to him yeah here he goes squeezing norman there he is oh cool he's a bit
stiffer to be marital aid he is yeah it's like um like back on the farm to us yeah yeah oh 67.
hang on at 65. there we go a bit more and that's smaller than the area 67 we're there 67 millif
come on norman all right james i'm coming you're up i'm coming with you there he is here let's go
oh yes give it a little bit of an injection there we go push it all in let's go oh 60 millimeters
that's beautiful this is gonna be better james right oh all done so the ego has 12 pence worth
of battery power within it and the petrol strimmer has 12 pence worth of petrol in it so yes they've
both got 2.4 millimeter line on the bottom and it's as equal as we can possibly make it so you've
got any other ideas how you like to test stuff please put it in the comments but anyway we're
gonna go with the petrol streamer first see how far we cut on the timer and then we're gonna do
the battery swimmer and see how we get on i don't know which one's gonna last longer and nor do you
let's crack them on all right that's primed choke on that's all fine one two three oh there we go
good
oh oh engine's changing
there she is she's out she is out how long was that i have no idea
oh five minutes what a tiny job though look at that i don't think i've been doing it before
right battery time yes switch hoover time for a battery streamer
right battery trimmer time same up through there follow the same line obviously it's a
loop handle that's a cow horn this is fine let's just go for it right ready oh that started well
so
oh there she is oh no that's her she is out she is out we have a red light flashing
oh yeah in actual fact i'm quite pleased that's out cause i'm knackered i'm knackered my arms
are pumping yeah right one two three four five five and three quarter rows against one
let's round it up if you want the conclusive results i think that's pretty much as clear as
it's gonna get the petrol machine done one strip that done what five and a half and what about
three times four times as long on time-wise so if you've ever asked a question whether petrol is
cheaper to run than battery hmm i think you better ask that question again anyway we're machinery
nation thank you very much for watching please like share and subscribe we'll see in the next one
