Can the 4745 charge a 24 V lead-acid battery?
Clore’s exact page and 4745 information sheet specify 24 V charging at 20 A or 2 A; the model manual has a voltage selector and 24 V error threshold, although one generic rate-guidance paragraph still says 12 V only. Use the 24 V modes only with the matching battery and current manufacturer instructions.

No maintenance stage is documented. The manual says the Charge Complete indicator comes on and the charger turns off. Choose equipment whose exact instructions establish a float/maintenance mode if that is the intended job.
Explore this need in the finder →Which 12 V medium rate should I use when the page says both 10 A and 20 A?
The exact page is internally inconsistent: one feature bullet says 10 A, while its title/specification box says 20 A. The linked 4745 control manual, model information sheet and photographed unit label support 20 A as the medium 12 V selection. We preserve the conflicting 10 A line and recommend verifying the latest model instructions; neither rate is automatically safe for a particular battery.
Explore this need in the finder →The CHARGE IT! 4745 is a 42 lb wheeled charger that Clore identifies for both 12 V and 24 V lead-acid charging. Its charge choices are not the same at each voltage: the documented 12 V arrangement is 40 A, 20 A and 2 A; 24 V offers 20 A and 2 A. A separate 230 A engine-start-assistance mode is for 12 V. There are two source conflicts worth seeing before shopping: one live-page bullet says 10 A for the 12 V medium setting, and one generic paragraph in the manual says 12 V batteries only. The exact model information sheet, page specification box, controls and image clarify the intended ratings, but those inconsistencies remain part of the assessment. This is source research, not a hands-on test.
12 V and 24 V are distinct operating plans
Clore’s model page and 4745 information sheet specify 12 V charging at 40/20/2 A and 24 V at 20/2 A. The exact operator’s manual describes a voltage selector, and its fault guidance recognizes over-voltage at both 12 V and 24 V. One general rate-selection paragraph nonetheless says the charger is designed for 12 V batteries only. Because the same exact-model manual elsewhere presents 12/24 controls and a 24 V error threshold—and the model-specific information sheet confirms the 24 V modes—the 24 V output is documented. Still, the copied-looking generic sentence means a buyer should verify the current manual and exact model setting rather than treating a quick-start interpretation as sufficient.
The 12 V 20 A medium rate has a different conflict: the live product page’s title/specification list says 20 A, but one feature bullet says 10 A. The linked 4745 manual lists 40/20/2 A controls; the exact information sheet calls 20 A the medium 12 V rate; the page’s specification box and the photographed unit also show 20 A. Those independent exact-model sources support 20 A as the manufacturer’s intended setting, so this assessment encodes 20 A and keeps the conflicting 10 A bullet visible. If selecting a seller package, verify that it is model 4745 and obtain the latest manufacturer instructions.
The top rate is not a direction to use 40 A on every 12 V battery. The manual advises using the battery maker’s charge-rate limits and supplies broad guidance for small, deep-cycle and maintenance-free automotive/marine batteries. Its chart includes a generic 12 V-only statement, so do not apply that chart to 24 V batteries or infer a specific 24 V battery-size rule. The public finder treats current as the charger’s available maximum in one supported plan, not as a safe current for an individual battery.
Lead-acid charging, not a documented maintainer
The model manual limits use to lead-acid batteries, and the exact product page tags the 4745 as AGM-related. The manual also supplies rate guidance for maintenance-free automotive/marine and deep-cycle batteries, but there is no dedicated user-selectable AGM profile in the reviewed material. The product sources do not establish lithium charging or an associated BMS condition. Likewise, they state no minimum or maximum Ah charging range. A 40 A label should not be converted into an invented capacity recommendation.
“Fully automatic” describes charging operation, not an ongoing storage-maintenance promise. The manual says the Charge Complete light comes on and the charger turns off after a full charge; it does not describe a float stage or permission to leave it connected indefinitely. If you need long-term battery maintenance, compare a model whose exact instructions explicitly describe that stage. The 4745 has one clamp output arrangement, not multiple independent banks.
The 230 A setting is for a separate 12 V start-assist routine
The 230 A start-assistance rating is not battery-charging current and is not a 24 V start rating. Clore’s manual describes a sequence that starts with several minutes of charging at a suitable rate, then selects Engine Start. The mode lasts 30 seconds; a starting attempt should stop after three or four seconds, followed by a three- or four-minute rest. The unit includes thermal protection, but repeated cranking can still overheat the charger or damage the vehicle starter. The manual also warns against using the start mode without a battery in the vehicle and notes that some vehicle electronics may be harmed. Read the vehicle owner’s manual first. A wheeled AC charger with start-assistance is not a replacement for a portable battery-free jump starter.
Shop placement and physical tradeoffs
The unit weighs 42 lb, so the wheels help with movement around a service area but do not make it portable in the small-tool sense. It requires a nominal grounded 120 V, 60 Hz outlet and indoor placement; the manual says not to expose it to rain or snow. No IP rating, wet-weather use permission, exact DC lead length or complete seller-package contents are stated in the reviewed sources. Check outlet access, measure the route, provide a dry ventilated area and confirm the current included clamps/cables before ordering. The exact page lists a one-year limited warranty; verify current terms.
Compared with the neighboring 4735, the 4745 adds documented 24 V charging, raises the 12 V medium setting according to the manual and sheet, provides a 20 A 24 V setting, and has a higher 230 A 12 V start-assist rating. It is also nine pounds heavier than the 33 lb 4735. The 4735 is simpler for a 12 V-only shop that needs the 40/10/2 A menu; neither is a multi-bank maintainer or a light trunk charger. Choose by confirmed battery voltage, chemistry, permitted charge rate, start-assist need, outlet and placement—not by headline amperage alone.
Before connecting, confirm the exact 4745, the battery’s nominal voltage and lead-acid chemistry, the safe rate stated by the battery maker, a grounded indoor 120 V outlet, and safe vehicle start-assist procedures. Review Clore’s official CHARGE IT! 4745 page, linked 4745 operator’s manual and 4745 information sheet alongside the vehicle and battery instructions.
