Why Proper Battery Storage Matters for Suex DPVs

Suex DPVs use high-performance lithium-ion batteries designed for powerful, reliable propulsion. But like all lithium batteries, they require specific care when not in use—especially during long breaks from diving.

Improper storage is one of the most common reasons DPV batteries fail prematurely. And because Suex batteries are a major investment, protecting them through proper storage is the easiest way to avoid costly replacement.

The Most Important Rule: Fully Charge Your Battery Before Storage

Unlike consumer electronics, Suex batteries must always be stored fully charged.

Here’s why:

• Lithium-ion batteries experience a slow, continuous self-discharge—even when disconnected.

• If voltage drops too low, the battery’s internal protection system can permanently disable it.

• Once the BMS (Battery Management System) locks the battery for safety, it cannot be revived.

This is exactly what happens to many divers who put their DPVs away for the winter and don’t charge them again until spring—the battery voltage falls too low, and the pack becomes unusable.

Recharge Every 60 Days During Storage

Suex requires the battery to be recharged at least once every two months during periods of inactivity.

This keeps the battery above its minimum safe voltage and ensures the BMS never enters a permanent shutdown state.

If you only take one thing away from this guide, let it be this:
Fully charge the battery, then recharge it every 60 days until you start diving again.

Important: Suex Chargers Are Not Trickle Chargers

The Suex charger stops charging once the battery is full—it does not maintain or “float” the battery at a safe voltage.

For that reason:

• Do not leave the battery connected to the charger long-term.

• Charge it fully, disconnect it, and put it away.

• Set a reminder to recharge again in 60 days.

Leaving the battery plugged in continuously can cause unnecessary stress and does not protect it from deep discharge.

Other Best Practices for Storing Your Suex Battery

Keep It Cool and Dry

Store the battery in a stable environment—generally between 50°F and 77°F (10°C to 25°C).
Avoid hot garages, cold sheds, cars, or anywhere humidity is uncontrolled.

Disconnect the Battery

If your DPV is an XJ or XK, remove the battery entirely for storage.
For VR-Series scooters, it’s safe to leave the battery installed—but the 60-day charging rule still applies.

Protect It Physically

Use a padded case or dedicated DPV storage area.
Avoid impacts, crushing, or long-term exposure to vibration.

Inspect It Periodically

Every couple of months, check for:

• Moisture

• Corrosion

• Damaged connectors

• Unusual smells or residue

If anything looks off, do not use the battery until it’s inspected.

How Long Can You Store a Suex Battery?

Lithium batteries can sit unused for several months only if properly maintained.
That means:

• Fully charge before storage

• Recharge at least every 60 days

• Store in a stable environment

If a battery sits uncharged for too long, it can fall below safe voltage and become permanently unusable—an expensive but preventable outcome.

Why Proper Battery Care Matters

A well-maintained battery provides:

• Maximum burn time and range

• Safe, predictable performance at depth

• Long-term reliability

• Lower ownership cost over the lifespan of your DPV

Protecting your battery means protecting your dives, your scooter, and your investment.
