Moba vs ClearWatt: Battery Test Comparison
Compare Moba and ClearWatt EV battery health tests. CARA-approved fleet diagnostics vs passive driving analysis for UK car dealers.
Moba vs ClearWatt — How Do They Compare?
Moba and ClearWatt represent two distinct philosophies in EV battery health testing. Moba delivers data-intensive diagnostics built for the dealer and fleet environment. ClearWatt takes a consumer-first, passive testing approach that analyses battery health during normal driving.
Here is how they compare for dealers evaluating their options.
Side-by-Side Comparison
| Feature | Moba | ClearWatt |
|---|---|---|
| Test method | OBD-based diagnostic platform | Passive testing during normal driving |
| Certification | CARA approved | No independent certification |
| Accuracy | Not publicly stated | Not publicly stated |
| Test time | Varies by test type | Requires driving period |
| Vehicle coverage | 90%+ fleet compatibility | Growing coverage |
| Cell-level analysis | Limited cell-level data | No — A+ to D grading system |
| Price point | Enterprise pricing | Consumer app model |
| Key partnerships | Arnold Clark (200+ branches) | Department for Transport backed |
| Unique advantage | 4 billion+ data points | Patent-pending ClearWatt Engine, 50+ indicators |
What Each Provider Does Well
Moba's Strengths
Moba brings serious data infrastructure with 4 billion+ data points powering their diagnostic algorithms. CARA approval provides UK industry recognition. The Arnold Clark partnership across 200+ branches demonstrates real-world deployment at scale.
Strong DoIP capability gives Moba an edge with Chinese EV brands entering the UK market. Their Certify Pro product is specifically designed for dealer environments, and their fleet compatibility exceeds 90%.
ClearWatt's Strengths
ClearWatt has created a genuinely innovative approach with passive testing. Rather than requiring a dedicated test session, their patent-pending ClearWatt Engine analyses 50+ indicators during normal driving. The A+ to D grading system is immediately understandable to non-technical users.
Department for Transport backing signals government confidence. For consumers and fleet operators who want ongoing battery health monitoring rather than point-in-time snapshots, ClearWatt fills a real gap.
Key Differences
Active vs passive: Moba performs active diagnostics — plug in, test, get results. ClearWatt analyses passively during driving. For dealers, active testing is more practical because vehicles need to be certified at intake, not after driving.
Dealer vs consumer orientation: Moba is built for the trade — enterprise pricing, fleet-scale deployment, CARA approval. ClearWatt started as a consumer product and is developing its dealer proposition. This shows in the product design and partnership profile.
Data approach: Moba's 4 billion+ data points represent historical diagnostic data from across their network. ClearWatt's 50+ indicators represent the breadth of metrics they analyse per vehicle. Different approaches to achieving diagnostic confidence.
Output: Moba produces diagnostic reports suitable for trade use. ClearWatt produces a consumer-friendly A+ to D grade. For buyer-facing certification, neither format carries the weight of an independently certified health certificate.
What Neither Provider Offers
Both Moba and ClearWatt share limitations when measured against the highest market standard:
- No TUV certification — Moba has CARA approval; ClearWatt has none. Neither has TUV certification
- No verified accuracy figure — Neither publishes validated accuracy tolerances
- No comprehensive cell-level heatmap — Neither produces individual cell condition maps with severity indicators
- No energy-based SoH — Neither uses the more accurate energy-based State of Health methodology
For dealers who need independently certified, cell-level battery health evidence, Battery Health Check powered by AVILOO offers TUV-certified testing with +/-3% verified accuracy and full cell-level analysis in 3 minutes.
The Bottom Line
For dealers, Moba is the stronger choice between these two — it is built for the trade, has CARA approval, and delivers active diagnostic results at the point of need. ClearWatt is better suited to consumers and ongoing monitoring.
However, for the highest standard of independent certification and diagnostic depth, neither matches the TUV-certified, cell-level analysis available through Battery Health Check.
