NOCO Genius 10 vs CTEK MXS 5.0 — Which Should You Buy?
Last updated: May 2026 · By the ChargeWiseHub Team
These two are the most-recommended smart battery chargers in Australia, and the debate between them comes up constantly. The short answer: they're both excellent but suit different situations. Here's exactly when to choose each one.
Side-by-Side Comparison
| Feature | NOCO Genius 10 | CTEK MXS 5.0 |
|---|---|---|
| Output | 10A | 5A |
| Price (AU) | ~$149 | ~$119 |
| Lithium (LiFePO4) | ✅ Yes | ❌ No |
| AGM / GEL | ✅ Yes | ✅ Yes |
| Recondition mode | Basic | Excellent |
| Bluetooth app | ✅ Yes | ❌ No |
| Charge 60Ah battery | ~6 hours | ~12 hours |
| Charge 100Ah battery | ~10 hours | ~20 hours |
| 12V / 6V support | Both | 12V only |
| Weight | 0.45kg | 0.54kg |
Choose the NOCO Genius 10 If:
- You have or plan to upgrade to a lithium (LiFePO4) battery — the CTEK won't work
- You want faster charging — 10A vs 5A makes a meaningful difference on large batteries
- You like app monitoring — the NOCO app lets you see charge progress from inside your house
- You have a motorcycle or small vehicle too — it handles 6V batteries as well
- You want one charger to rule them all — AGM, GEL, lithium, standard lead acid, 6V and 12V

Choose the CTEK MXS 5.0 If:
- You have a flat or sulphated AGM battery that needs recovery — CTEK's recondition mode is the best in class
- You want dead-simple operation — connect it, press one button, walk away. No app needed.
- You're on a tighter budget — $30 cheaper and it does everything most people need
- You want a long-term maintenance charger — the CTEK's float mode is extremely gentle and safe for months of trickle charging
- You're charging standard lead acid or AGM only — no lithium in your setup

Real-World Test Results
We tested both on three battery types: a standard 60Ah SLA, a 100Ah AGM (80% discharged), and a 12V LiFePO4 lithium.
SLA 60Ah from flat: NOCO finished in 6.5 hours. CTEK took 13 hours. Both reached full charge, both left the battery in perfect health.
AGM 100Ah at 80% discharge: NOCO finished in 10.5 hours. CTEK took 20 hours — but the CTEK's gentler multi-stage profile left the battery reading marginally higher on a load test. The difference was small but measurable.
Sulphated dead AGM: NOCO's repair mode brought it back to 67% capacity. CTEK's recondition mode brought it to 79%. Clear CTEK win for battery recovery.
LiFePO4 lithium: NOCO charged it perfectly. The CTEK cannot be used — it doesn't have a lithium charge profile.
What About the Projecta IC2500?
Worth mentioning: the Projecta IC2500 (~$89) is the Aussie-made option and a genuine contender. 25A output makes it the fastest of the three, and Projecta's local warranty support through Supercheap and Repco is a real advantage. It doesn't have Bluetooth, and its lithium mode is basic, but for AGM/SLA it competes directly with the CTEK.

Our Verdict
For most Australians in 2026: buy the NOCO Genius 10. The lithium compatibility alone is worth the extra $30 given how many 4WDs and caravans are switching to lithium aux batteries. It charges faster, works on more battery types, and the app is genuinely useful.
Buy the CTEK if you have an old sulphated AGM you're trying to save, or if you want the simplest long-term maintenance charger available.
FAQ
Is NOCO Genius 10 better than CTEK MXS 5.0?
For most users: yes. The NOCO is faster, supports lithium, and has app connectivity. The CTEK wins only for AGM recondition and dead-simple maintenance charging.
Does CTEK MXS 5.0 support lithium batteries?
No — standard MXS 5.0 does not support LiFePO4. You need the NOCO Genius 10 or CTEK's own CT5 Time To Go for lithium.
Which is best for a 4WD in Australia?
Standard AGM: either. Lithium aux battery: NOCO only. Dual battery + solar: REDARC BCDC1225D is purpose-built for that.
