24V-80V 30A Lead-acid Battery Intelligent Charger

•A 24V-80V 30A Lead-acid Battery Intelligent Charger, with output voltages ranging from 24V up to 80V and a 30A charge rate could suit a variety of lead-acid battery types and capacities. However, this charger can only charge lead-acid batteries within that voltage range—it is not compatible with other battery chemistries.

•For proper lead-acid battery charging and safety, choose a charger that provides an “intelligent” multi-stage charge cycle with the correct voltage set points for each stage based on your specific batteries.

Typically 3 stages:
1. Bulk charge at 30A for rapid recharging. The bulk voltage must suit the target battery specs.

2. Absorption charge at a lower voltage to fully charge the batteries without overheating. For example, 28.5-29.2V for a 24V battery or 54-58V for an 80V battery.

3. Float charge for maintaining charge with a 13.5-13.8V (24V battery) or 27-28V (80V battery) reduced voltage.

•The charger should have safety features like overload protection, short circuit protection, reverse polarity detection, ignition protection if used in hazardous locations, and a rugged enclosure for outdoor uses.

•The “intelligent” features refer to the charger continuously monitoring the battery voltage and temperature to adjust and switch between charge stages. This helps provide safe, efficient charging based on the lead-acid battery specs and state of charge. Communication may require a separate charge controller or be integrated within the charger.

•Carefully match the max charge voltage to your target battery. While the charger handles a range, the peak voltage for any stage must not exceed the battery specs. A voltage that is too high could potentially damage the battery. Choose a charger with a maximum voltage closely matching your batteries.

•Be aware that improper charger selection or settings could void battery and equipment warranties. Follow the manufacturers’ recommendations for charger compatibility, usage, and voltage settings.

•Consider the enclosure rating for your environment. Weather-resistant may be needed for some applications. Weight, handles and cable should suit portability needs.
