What features should I look for in a battery tester?

Look for features like voltage range, compatibility with different battery types, and ease of use. A tester with a voltage range of 6V to 24V is versatile for most applications.

How accurate are battery testers?

Battery testers are generally accurate within a margin of 0.5% to 1% for voltage readings. Ensure the tester is certified by bodies like Underwriters Laboratories (UL) for reliability.
