We get quite a few calls about the new DPI (Diversified Power International) golf cart battery charger and the mode select settings. Here is a quick look chart to double check your golf cart charger is running the correct MODE for your batteries.
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 (see DPI Gen IV here).
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 and most parts stores… ( Usually they are a black or grey box with the company sticker on it – which equates to usually being manufactured in Mexico or Korea – hence other alloy inside battery besides lead because they use reclaimed lead and is not nearly as pure as something found in a quality battery still made in the US and why you get what you pay for when it comes to batteries.
Batteries are the heart of your golf carts system so spend a little more and you will be glad you did.
Cycle life and performance will become apparent over time when using a half rate “cheaper battery”) But a quality battery like Trojan Golf Cart Batteries or US Batteries they like to be charged hotter than most.
Just the chemistry itself and the internal characteristics of these quality batteries like to be energized to the point of bubbling or boiling. Especially when batteries are new – the lead is not 100% cured and usually requires 15-25 charge cycles to completely cure the lead. In this phase of a batteries life it is paramount to energize the cells effectively for 100% performance and longevity.)
- 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:
Absorption Voltage Figures
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.
