Any mainstream Raleigh dealer should be able to help, since in the UK it's really only Raleigh that still use TranzX drive systems on some of their e-bikes, and they would (I assume) still maintain a relationship/account with TranzX.

There are some ebay sellers that sell compatible batteries.

Alternatively, you could likely have it re-celled: ebikebatteries advertise here and have a good reputation with many members here for re-celling.

Yes. Many bike brands use premium cells - Samsung, LG, Panasonic etc - that do cost that much. TranzX use premium cells. Availability has become more difficult and costs have escalated considerably in recent years.

Third party sellers on ebay usually use unbranded cells (or branded with names we don't readily associate with premium cells) which makes their batteries much cheaper. That doesn't necessarily make them bad, just not quite as good but still perfectly serviceable.
