Specifications
| Price (US) | Not published ctek.com returned HTTP 429 (rate-limited) on every attempt this session, and no other retailer page (BatteryStuff, RevZilla, Cyclegear) could be fetched (403/blocked) to confirm a current US price. Street price for the MXS 5.0 is commonly cited in the $90-$110 range by third parties, but that figure is not used here since it was not confirmed on a fetched primary source. |

Source: manualslib.com (read 2026-08-01) STALE · 2026-08-01 . ctek.com/us/products/mxs-5-0 (the manufacturer page) returned HTTP 429 on every fetch attempt in this session, including after multiple cooldown waits, so specs were instead read from CTEK's own owner's manual text as mirrored on ManualsLib. VERIFIED: max output 4.3A (the "5.0" in the model name is CTEK's line designation, not the literal charge current), 12V-only, charging range 12.6V-14.7V with 15.8V peak, 8-step program (desulfation/soft-start/bulk/absorption/analysis/reconditioning/float/pulse), LED step indicators, and built-in ambient-temperature charge-voltage compensation (-20C to +50C). waterproof_rating and reverse_polarity_protection are left null: the manual excerpt only gives a general "do not expose to rain or snow" caution and does not clearly restate a verbatim IP figure or an explicit reverse-polarity-protection claim in the text actually retrieved, so neither is asserted rather than risk copying an unverified number. No freely-licensed image could be sourced: the only CTEK-tagged photo on Wikimedia Commons ("Auxiliary Battery & CTEK charger.jpg") was inspected and shows a different product (a CTEK D250S DC/DC charger), so it was rejected as misleading and no image is included for this entry.
