Hello again, I’m starting to delve into the confusing world of leisure batteries and would love some recommendations. We are thinking that we’ll be on grass pitches for most of our future holidays and will get a 12v inverter at some point. My main confusion is, when I search for a NCC Class A battery and click on the link, invariably after some scrolling it turns out to be a C or B. Is it possible to get a decent Class A for under £150? Many thanks.

Oh okay, I was thinking of the inverter to do the phone charging and the occasional toaster. I shan’t over complicate things then. Thank you Colin, I’ll have a look at the link.

…and I’ve not even attempted to look at the fridge and how to operate it yet!!

got exide gel es1300 from a motor factor who is a dealer for them it was specially ordered in. was cheaper than online
its taller than old battery yet has more ah than old, we use solar and inverter

the es1200 may fit in your under seat space better however

all depends on what do with power

there are solar chargers lifepo4 with sinewave inverters built in, chrome van city van life in ca just reviewed one
they are a eyewatering cost
unless keep looking like black friday or prime day,
bluetti, jackery, ecoflow, anker, many more brands and sizes

they welded steel narrowboat on youtube with the huge anker!
huge ecoflow drove electric narrowboat motor

the old style gel battery info is page 7 if helps https://www.tayna.co.uk/docs/catalogues/...ry-Brochure.pdf

I would forget the inverter. Get a usb port something like this. https://www.amazon.co.uk/Charger-Waterpr...896416531&psc=1. That would take care of phone charging. Maybe a blowlamp for the toast.

I use a 300W inverter driving an 18W domestic Samsung 21" TV. The inverter claims to be 95% efficient. Even if it was only 90% efficient the power draw would be 20 Watts.
The 12Vdc Avtex TV draws about 30 Watts so guess which one is more efficient when off grid?

Also the Avtex is about 3 times the price of a standard domestic TV.

You can use your hob to do toast with a Ridgemonkey.

we have a 500w inverter (its factory fitted) and wired in such away in to bip, powers all the sockets. power also goes through charger so is an electrical loop, there may be loss have never found to be an issue, however the solar helps there. you learn to charge use power, when its daylight. we turn off when not needed because has a easy to use remote switch. the solar keeps the battery in a charged state so lasts for 18 years in our case
also have a 1500w inverter belt and braces its not connected unless needed so no drain on system.
we a have 240 led pendant light with lampshade, this works really well for 2 reasons very bright 2 stops us walking into rear low roof, that does hurt in case not aware.
eye strain also hurts.
pure sine wave is kinder to sensitive electricals like a laptop.
watch a few van builds on youtube, they always have solar a battery system and inverter. some are now going with the solar generators.
narrow boaters have solar and victron battery bank
some house holds are also buying solar generators to run items to save the electric bill.
everything has a negative, whether weight or some power loss, investment costs
the positives are can go anywhere, there wont be a need to pay for electric on site,

my advise is simple choose the way you want to go or not.

Thank you everyone for your detailed and useful replies, I’ve only just seen them! We are thinking that simple is best. Purchased the 12v USB charger sockets and like the idea of the Ridgemonkey toaster! We've borrowed a battery from our local garage to give us an idea of what we need, I think we're slowly finding our feet. I'm six foot four, so have clonked my head on the rear cupboard many, many times!!
