Is your cordless drill refusing to charge? Does your angle grinder battery die mid-project? You''re not alone. In Costa Rica''s growing construction and DIY sectors, lithium battery failures cost businesses $1.2 million annually in productivity losses. This guide reveals professional repair strategies, maintenance best practices, and smart alternatives to keep your tools running.

Why Lithium Batteries Fail in Tropical Climates

Costa Rica''s average 80% humidity and 27°C temperatures accelerate battery degradation. Common issues include:

• Swollen cells from moisture absorption
• Corroded connectors (12% of tool failures)
• Balancing circuit failures

Case Study: San José Construction Firm Saves $8,400

After losing 18 batteries in 6 months, Constructores del Pacífico implemented our 3-step maintenance protocol:

1. Monthly terminal cleaning
2. 40-80% charge maintenance
3. Professional recalibration every 6 months

Result: 73% reduction in battery replacements.
