1. WHAT IS THE BOTTOM LINE?
1.1. At the first sign of slow starting, headlights dim at idle, gauges indicate discharge with engine running at high idle, or your battery seams to be loosing performance, recharge, remove the surface charge, and load test it! Weak or bad batteries also can cause stress or premature failures of charging systems and starters. (Please see Section 4.)
1.2. Perform regular preventive maintenance, especially during HOT weather and before COLD weather. (Please see Section 3.)
1.3. In hot climates use non-sealed batteries, so you can replace lost water and avoid high temperatures. (Please see Section 7.)
1.4. Keep the battery charged, but avoid overcharging. (Please see Section 9.)
1.5. Buy the freshest and largest Reserve Capacity (RC) battery that will physically fit in your vehicle, making sure that the Cold Cranking Amp (CCA) rating for your climate that meets or exceeds the car's Original Equipment Manufacturer's (OEM) cranking amp requirement. (Please see Section 7.)
1.6. After deep discharges or jump-starts, recharge your battery, remove the surface charge, and load test it for latent damage. (Please see Section 4.)
1.7. Temperature matters! Heat kills car batteries and cold reduces the available capacity.
