Battery Cycles Explained: How Many Per Day is Safe?
Quick Answer
Most home batteries are rated for 6,000-10,000 cycles. One full charge and discharge equals one cycle. Running 1-2 cycles daily (typical for arbitrage) means your battery should last 10-15+ years. Quality batteries like Tesla Powerwall and Duracell guarantee at least 70% capacity after 10 years.
