The programme's credits and break-bumpers, created by Burkitt DDB, show the animated Mr Energizer character catching a rechargeable battery and use the strapline 'Energizer Rechargeables for today's high-tech gadgets'.
Energizer first sponsored The Gadget Show last year, using the deal to promote its Ultimate Lithium batteries with spots featuring an inventor pitching gadget ideas.
The battery manufacturer is focusing on developing further rechargeable products this year.
The sponsorship, brokered by Mediaedge:cia, is being supported by point-of-sale material featuring the line 'Energizer. Powering The Gadget Show'.
