Replace hybrid battery on '07 Camry with 70k miles or sell?

Hi all, I inherited an '07 Camry hybrid a few years back and recently the hybrid battery died. It spent it's whole life in AZ and now CA and is currently sitting at 70k miles. The car still functions without the hybrid system, but I need to do an emissions check at the end of the month which I'm told I'll fail due to the check engine light being on for the battery. My local shop told me one of the cells died and quoted me at $3.3k to install a new battery, and I'm trying to decide if it's worthwhile. I have a family member who is willing to gift me a '12 prius with 150k miles, so I luckily wouldn't need to buy another car if I sell. Would appreciate any advice anybody has, thanks in advance.
