For auto parts and battery sellersCalifornia's battery fee and the core deposit.
Coreline puts California's $2.00 lead-acid battery fee and your refundable core deposit on their own invoice lines for California orders, and can charge the deposit elsewhere too. It holds one deposit per battery. When a core comes back, it checks the group size matches and that it is within 45 days before saying refund. Deposits past 45 days with no core can be marked kept. A To do list shows deposits near or past 45 days and batteries missing a group size. Not tax advice.
