Buying Guide

The key factor is compatibility. Most solar garden lights require standard 1.2-volt NiMH AA cells, and the wrong chemistry or size can damage the light or prevent charging.

• Battery chemistry: Choose rechargeable NiMH batteries rated at 1.2 volts. Do not use 1.5-volt lithium or alkaline replacements unless the light specifically allows them.
• Capacity: Look for 1,900 to 2,500 mAh. A 2,000 mAh cell generally gives longer operation than a 600 mAh cell, though the panel and LED also affect runtime.
• Low self-discharge: Pick cells that retain at least 70% of their charge after 12 months. This matters when winter weather keeps the lights off for weeks.
• Pack size and cost: Buy a four-pack for one or two fixtures, or an eight- to 16-pack for several lights. A reasonable price is about $10 to $25, depending on capacity and brand.
• Outdoor durability: Check for a sealed battery compartment and use cells rated for roughly 32°F to 113°F. Store spare batteries indoors during freezing weather to reduce capacity loss.

If you must compromise, prioritize the correct NiMH chemistry and a capacity near 2,000 mAh.
