Hybrid batteries last between 6 and 10 years, so your Cadillac ELR may need a new battery within the next few years. RepairPal estimates that a Cadillac ELR battery upgrade costs between $9,597 and $9,698. To break that down, the battery itself costs around $9,200, while labor ranges from $250 to $500.
Remember that this price doesn’t include taxes and fees or any parts that need replacement.
Most hybrid vehicles have a 10-year battery warranty, so check with Cadillac before replacing your battery. If your battery doesn’t need replacing and you simply want to upgrade, it will likely come out of your pocket.
