Looks like 9 Ah is the new 7 Ah. Ebay is full of them.

They do not get any gas from Russia AFAIK, whatsoever. Please correct me if I'm wrong though.
So how come prices are skyrocketing there? The UK is not even part of the EU anymore, so it's not a matter of decisions from the EC either. What is it? I'm curious and not the only one wondering, so if some enlightened people can explain this to us.
The OP's title looks quite right.

I have come across a different view of why the gas price is so high. It's an international market with international prices. The reason it's gone nuts partly the Ukraine war. But not entirely. The war caused a shock to the price, which started the price bouncing under volatility. The number of companies trading in the international natural gas market went from 9 when the market was stable to over 200 when it destabilised. These are option traders and speculators, buying low and selling high. Their entire goal is to keep that price volatile so they can scrape the profits off of it.
Worst though, the energy companies are whining about the RISK cause by the price bouncing, so they lift their consumer price to protect themselves. However they also purchase energy futures to offset their risk. The net is, when the price is down your utility company are making record, bumper profits. The price is bouncing massively.
It's correct the UK don't import gas, oddly, Ireland is a net exporter of natural gas.
So it does bear a question.... why can't the UK and Ireland take it's gas off the international market and sell it to us for sensible "localised" prices.

Well that will never happen for two reasons:
1) It is a sensible idea
2) The rich wont become richer.

Netherlands has the same issue, we pump up 20 billion m3 a year and export 17.5m3 for a price twenty to thirty times lower than the current market price.
And the inconvenient truth here is that our government or whoever they assigned the rights to signed very long lasting contract to other eu countries.
Morons, short term profit seekers. The only country I know of who was smart enough to put thecearnings from their gas fields into a mutual fund and now earns billions per month is Norway.

Either way, at the rated load, you'll get less than 5 minutes of inverter time to do a controlled shutdown (assuming you're protecting a PC). Realistically a PC running at say 200W, you'll get probably thirty minutes or so depending on the low battery voltage shutoff settings. The batteries aren't going to be very happy in any case though.[/color][/size][/b]

9Ah is the most common size of SLA battery I've ever encountered, they're the same external dimensions as the 7Ah type. Of course in UPS duty you don't get anywhere near that rating, which is for a far slower discharge.

Never seen one here in 30 years in the business. Sounds like it's a 7 that's just been qualified at a different, lower, discharge current. Either that or it's a Chinese "9Ah" like those 900,000mAh power banks and 5000mAh 18650's on ebay.
