Re: Requesting Battery Backup

Just out of interest, are these battery back-up units for the SmartHub?

If so, are they available for non-BT customers to buy?

I'm with Plusnet now, but the routers are basically the same.

@Paul608085 

They are for the Smart Hub 2 to allow BT Digital Voice to work in the event of a power cut, so people still have a phone service.

As a Plusnet customer its not going to affect you, unless you use your phone line. In which case you will have to be migrated to BT Retail, as Plusnet are no longer providing a phone service.

The (12V) backup units can be be purchased, but they are expensive and in short supply.

Thanks for the reply.

Although I don't have Digital Voice, or use the Plusnet landline, I rely on WiFi Calling as the EE signal is poor inside my home.

When you say "expensive", do you have any idea of the cost - or can you tell me the correct name of the item? I have tried looking on the EE Shop, but they either don't sell them, or I'm using the wrong search terms.

I have another plan to "lash" something up with an old 12 volt battery pack I have, but the purpose designed device would probably look neater as our Plusnet Hub is in a prominent position in the lounge.

Re: Requesting Battery Backup

They only have a relatively short back up life though, don't they? Not more than an hour or so, or have I got it wrong?

They were about £85 and lasted about an hour.

Far better and cheaper to sort out your own 12V backup system.

Thanks for the replies.

I'm on FTTC, so I think that the weak link in the chain is the batteries in the cabinet - which I believe are only spec'd to maintain service for about 30 minutes if the mains supply fails?

Assuming that is correct, being able to keep our router running for an hour would be more than adequate.

Keith - if you can find a link, or the proper name for the item, I will try to see if they are available second-hand maybe.

I have posted a link.

For close that price you can get a mains UPS that will do the same thing.

Or even this may work, if you really get that many power cuts.

"I have posted a link."

Sorry - I missed that.

Unfortunately, the item is out of stock. Probably why it didn't show up on my search?

I will re-investigate my own solution.

IIRC, the DC power connector is a "non-standard" size. I do have a spare mains PSU for the SH2 that I could butcher, but I'm reluctant to do so just for the power connector.

Do you happen to know the DC plug dimensions please?

Re: Requesting Battery Backup

No idea of the plug, but someone did post it on the forum.

I use a mains UPS to power home hub 4, and associated  stuff.

I am on ADSL, so I do not have to worry about a power loss at the cabinet.
