Quick Answer

To get the most from your camera batteries, focus on proper charging habits, avoid extreme temperatures, and store them partially charged when not in use.

Why Temperature Matters

Lithium-ion batteries, like the ones in most modern cameras, are sensitive to heat and cold. Extreme temperatures can permanently reduce capacity and shorten overall lifespan. Avoid leaving batteries in a hot car or in direct sunlight, and don't use them in freezing conditions for extended periods. If you're shooting in cold weather, keep spare batteries in an inside pocket to stay warm.

Charging Habits That Help

You don't need to fully drain a lithium-ion battery before recharging—that's an old habit from older battery types. In fact, partial discharges are better. Try to recharge when the battery reaches about 20-30% remaining. Also, avoid leaving the battery on the charger after it's fully charged for long periods, as this can stress the battery over time.

Steps to Care for Your Camera Batteries

  1. Charge with the right charger: Use the charger that came with your camera or a compatible replacement. Avoid cheap, unverified chargers that may overcharge or damage the battery. Check that the charger matches your battery model.
  2. Avoid full discharges: Don't wait until the battery is completely dead to recharge. Lithium-ion batteries prefer partial cycles. Recharge when you see the low-battery warning, usually around 20%. Keep a spare battery on hand to avoid running out.
  3. Store batteries at partial charge: If you won't use the battery for a while, store it at about 50% charge in a cool, dry place. Avoid storing it fully charged or completely empty. Check stored batteries every few months and top them up if needed.
  4. Keep contacts clean: Wipe the metal contacts on the battery and the camera with a dry cloth occasionally. Dirt or corrosion can prevent proper connection and reduce performance. Use a soft, dry cloth—never wet or abrasive materials.
  5. Protect from extreme temperatures: Don't leave batteries in direct sunlight or in a hot car. In cold weather, keep spares in a pocket close to your body to maintain performance. Let a cold battery warm up before using it.
