Summary: Discover expert tips for maintaining power tool batteries in San Diego''s unique climate. Learn how temperature, charging habits, and storage solutions impact battery life – and how to avoid costly replacements.

Why Battery Care Matters in America''s Finest City

San Diego''s mild climate might seem perfect for power tools, but did you know our average humidity of 67% accelerates battery corrosion? Proper maintenance isn''t just about saving money – it''s about maximizing productivity for contractors, DIY enthusiasts, and landscaping professionals across the county.

Top 5 Maintenance Mistakes to Avoid

• Using mismatched chargers "just this once"
• Ignoring contact point corrosion from coastal air
• Draining batteries completely before recharging
• Stacking batteries horizontally during storage

Climate-Specific Storage Solutions

Data from SDGE shows 63% of tool batteries fail prematurely due to improper storage. Here''s how local pros protect their investments:
