EMIT-UK offers a battery replacement service for your old V3 eCard. Send us your old card and we will replace the battery for just £36 & £2 postage. If the card LED is damaged and we cannot fix it, we do offer a £5 discount on a refurbished V3, so £44 not £48, that's provided you send us your old V3 eCard.
Whatever option you want send your old card to 80 Spring Lane, Eastleigh SO50 6BB, remembering to include a return address. If you do not pay online via paypal then please include a cheque to EMIT-UK. For the replacement service please allow 3 weeks from our receipt of your eCard.
Unfortunately we cannot replace batteries in standard V2 cards, but we do offer a £3 discount on any new card if you handover an old V2 card (the green/orange ones).
