FAQ: Waterproof Battery Selection

How deep can IP68 batteries be submerged?

Most IP68-rated units withstand 1.5m immersion for 30 minutes, but always check manufacturer specifications.

Do waterproof batteries need special maintenance?

While sealed units require less upkeep, we recommend biannual terminal inspections in harsh environments.

Remember: True waterproofing requires both battery cells and connection points to meet protection standards. Ask suppliers for detailed construction diagrams.
