What Do IP65, IPX6, and IP68 Mean? A Simple Guide to E-Bike Battery Protection Ratings
When choosing an e-bike or battery, you may come across ratings such as IP65, IPX6, IP67, or IP68.
What do these numbers mean?
Does a higher number always mean better water protection?
And can an IP-rated battery simply be cleaned with a high-pressure washer?
The key is to remember:
The first digit indicates dust protection; the second indicates water protection.
When purchasing an e-bike system kit, the battery's protection rating is key to determining durability and usage scenarios. TAKE-E has compiled an easy-to-understand visual guide to IP dustproof and waterproof ratings, helping you grasp key points during selection and use correct cleaning methods to extend battery life!
1. What is an IP Rating? What Do the Numbers Mean?
In TAKE-E's battery specifications, you will often see markings like "IP68", "IP65", or "IPX6". IP stands for Ingress Protection (International Protection Marking).
The two digits following "IP" represent different aspects of protection：
- First digit: Dustproof rating (0 - 6): The higher the number, the stronger the protection against solid dust intrusion.
- Second digit: Waterproof rating (0 - 8): The higher the number, the stronger the protection against liquid ingress in terms of time and pressure.
🔍 Dustproof Rating Details (First Digit)
- 0: No protection.
- 1: Protection against solid objects > 50mm.
- 2: Protection against solid objects > 12.5mm.
- 3: Protection against solid objects > 2.5mm.
- 4: Protection against solid objects > 1mm.
- 5: Limited dust ingress permitted; prevents dust accumulation.
- 6: Completely dust-tight; total protection against dust ingress.
💧 Waterproof Rating Details (Second Digit)
- 0: No protection.
- 1: Protection against vertically falling water drops for up to 10 minutes.
- 2: Protection against water drops tilted at 15° for up to 10 minutes.
- 3: Protection against water spraying for up to 5 minutes.
- 4: Protection against water splashing for up to 5 minutes.
- 5: Protection against low-pressure water jets for at least 3 minutes.
- 6: Protection against powerful water jets for at least 3 minutes.
- 7: Protection against immersion in 1 meter of water for up to 30 minutes.
- 8: Protection against continuous immersion deeper than 1 meter (time varies by manufacturer).
2. TAKE-E Popular Battery Face-off: Octaloop vs. Water Bottle
Different riding needs require batteries with matching protection characteristics:：
| Battery Model | IP Rating | Dustproof Feature | Waterproof Feature |
| Octaloop (Octagonal Battery) | IPX6 | Marked as X (No dust data / Unrated) | Level 6 (Protection against powerful water jets) |
| Water Bottle Battery | IP65 | Level 6 (Dust-tight IP6X) | Level 5 (Protection against low-pressure water jets) |
3. Kit Selection & Daily Cleaning Guide
After understanding the ratings, how should you apply this knowledge when purchasing and cleaning?
(1)Selection Advice：
Riding frequently on sandy, dirt, or off-road trails: Choose a kit with dustproof certification (such as the IP65 Water Bottle Battery).
Riding frequently in heavy rain or stormy conditions: Choose a kit with higher waterproof ratings capable of withstanding powerful water jets (such as the IPX6 Octagonal Battery).
(2)Daily Cleaning Rules：
When using IP65 batteries: Wash with a low-pressure hose; avoid pointing high-pressure water guns directly at battery seams.
When using IPX6 batteries: Capable of handling stronger water streams, offering higher safety during cleaning.
Do NOT submerge in water: Neither IP65 nor IPX6 has protection against prolonged water immersion. Never remove and soak the battery in water!
4. TAKE-E IP Rating Pop Quiz
Did you get all that? Challenge yourself with these quick questions:：
(1).Which battery is completely dust-tight?
Answer： Water Bottle Battery (IP65).
(2).Can the Octaloop (IPX6) be used in desert environments?
Answer：Not recommended, as it lacks dustproof testing data (X indicates no data).
(3).Which battery is safer if cleaning the bike with a powerful water sprayer?
Answer： OctaLoop (IPX6).
(4).Which battery has protection against long-term water immersion?
Answer： Neither has this protection!
