CTEK MXS 5.0

Averaged from + undefined
The verdict

The MXS 5.0 is the AGM-battery and long-term-storage specialist. CTEK's 8-stage charging program is the most sophisticated in consumer chargers, and the IP65 enclosure means it can live on the bench in a damp garage without issue. The 5-year warranty beats every other pick here. The trade-off is amps — 4.3A is slower than the NOCO Genius 10 and far slower than the 15A Schumacher SC1280 or BLACK+DECKER BC15BD. Buy this if you have AGM batteries, motorcycles, or a winterized boat or RV.

NOCO Genius 5
#1 · Top Score

NOCO Genius 5

Slowest amp rating in this round-up but most versatile feature set. Beats the BLACK+DECKER BC15BD on battery chemistry support (lithium + lead-acid). Loses on raw amps to the NOCO Genius 10, Schumacher SC1280, and BLACK+DECKER BC15BD. Cheaper than the Genius 10 and CTEK MXS 5.0 by a meaningful margin.

NOCO Genius 10
#2

NOCO Genius 10

2x faster than the NOCO Genius 5; slower than the Schumacher SC1280's 15A or BLACK+DECKER BC15BD's 15A. Lithium support beats the Schumacher and BLACK+DECKER (both 12V lead-acid only). More expensive than the Genius 5 and BLACK+DECKER, cheaper than the CTEK MXS 5.0.

Schumacher SC1280
#4

Schumacher SC1280

Fastest pick here. Beats the NOCO Genius 5 and CTEK MXS 5.0 on raw amps; ties with the BLACK+DECKER BC15BD at 15A. No lithium support — the NOCO Genius 5 and Genius 10 are the only picks here that handle lithium. 2-year warranty falls between the NOCO Genius 5/10 (3-year) and CTEK MXS 5.0 (5-year).

BLACK+DECKER BC15BD
#5

BLACK+DECKER BC15BD

Only pick with built-in engine-start. Tied with the Schumacher SC1280 on 15A speed and on lead-acid-only chemistry. Shortest warranty in this lineup (1-year vs 2-year Schumacher, 3-year NOCO Genius 5/10, 5-year CTEK MXS 5.0). LCD display more informative than the LEDs on the NOCO Genius 5/10 or CTEK MXS 5.0.
