You will find below a quick How To Guide to find and correctly set the charge MODE for your new DPI (Diversified Power International) Gen IV Accusense golf cart battery charger. This Mode select feature allows for fine tuning charger with a specific charge algorithm for the battery or chemistry of batteries in your application. So I decided to put together a short How to article about setting the charge mode for your new DPI Gen IV Accusense Golf Cart Battery Charger.
Looking for a new programmable smart charger for your golf cart ? Here is a complete section of the leading brands currently available.
The charger is factory preset to charge in MODE-1 which will cover all (Lead Acid or Flooded) golf cart battery applications. This is a auto sense – with a range of approx 200-255Ah with is a little hot for a cheap 8 volt golf cart battery from like Sams, Wal Mart most parts stores… ( Usually a black box with the company sticker on it – Usually manufactured in Mexico or Korea) But a quality battery like Trojan Golf Cart Batteries or US Batteries like to get charged hotter than most. Just the internal characteristics of these types or brand of batteries like to be energized to the point of bubbling or boiling people say. Especially when your batteries are new.
Lead is not 100% cured when coming off the manufacturers assembly line and just not cost effective for them to energize completely prior to shipping for distribution. This process usually requires 15-25 charge cycles to 50% D.O.D (Depth of Discharge) to completely cure the lead. In this phase of a batteries life it is very important to energize the cells effectively for 100% performance and longevity. It is also wise to charge a new set of batteries completely before putting into service. even though a new set of batteries show good voltage that does not mean they are 100% charged or saturated.
In the event you purchased the charger used or came with a golf cart recently purchased you might want to just check to confirm current mode selection.
If changing battery type, verify and re-establish the Charger MODE settings. See chart below:
NOTE: The Absorption Value is listed as Volts Per Cell and is one of the most important parameters pertaining to that charge algorithm. Different battery packs have differing number of cells – multiply the number of cells times the ‘Volts-Per-Cell’ value to obtain the voltage the charger will regulate during the Absorption Charge Stage.
For example; using MODE-2 ‘Absorption Voltage value of 2.400V/cell’ from the table above:
12V Battery Pack = 6 Cells Absorption = 14.40Vdc
24V Battery Pack = 12 Cells Absorption = 28.80Vdc
36V Battery Pack = 18 Cells Absorption = 43.20Vdc
48V Battery Pack = 24 Cells Absorption = 57.60Vdc
72V Battery Pack = 36 Cells Absorption = 86.40Vdc
For example; Lithium Battery MODES and using MODE-31
12V Battery Pack = 3 Cells Absorption = 12.52Vdc
24V Battery Pack = 7 Cells Absorption = 29.22Vdc
36V Battery Pack = 11 Cells Absorption = 45.92Vdc
48V Battery Pack = 14 Cells Absorption = 58.44Vdc
72V Battery Pack = 21 Cells Absorption = 87.66Vdc
Many rechargeable batteries share an exact or very similar profile to one of the battery types listed above. Contact DPI directly to ask for MODE setting for a battery type not listed. You can contact directly at 423-538-9002 or visit their website.
