We get quite a few calls about setting the charge mode for the new Accusense DPI (Diversified Power International) golf cart battery charger. Here is a quick look chart to double check that your golf cart charger is running the correct MODE for your batteries. The Mode select feature allows for fine tuning the charger with a specific charge algorithm for the battery or chemistry of batteries in your application.
The Basics
The Accusense DPI Golf Battery Charger is factory comes with a preset charge of MODE-1 which will cover all lead acid or flooded golf cart battery applications.
This is auto-sense (with a range of approx 200-255Ah) which is a little hot for an inexpensive 8 volt golf cart battery from stores like Sams, Wal-Mart, or most parts stores. Usually these batteries are in a black or grey box with the company sticker on it and come from Mexico or Korea. The alloy inside these batteries is usually a mix of lead and something else as they use reclaimed lead which is not nearly as pure as US made batteries. Pete\’s believes that batteries are the heart of your golf cart\’s 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 \”cheaper\” battery. A quality battery like those from US Batteries likes to be charged hotter than most so they are an excellent choice. These batteries should be energized to the point of bubbling or boiling. When batteries are new the lead is not 100% cured and usually requires 15-25 charge cycles to completely cure. In this phase of a battery\’s life it is paramount to energize the cells effectively for 100% performance and longevity.
Here are two other things to remember. If your charger is used comes with your golf cart, you might want to check to confirm current mode selection. Also, if changing battery type, verify and re-establish the charger MODE settings. See chart below:
Absorption Voltage Figures
NOTE: The Absorption Value in \”Volts Per Cell\” is one of the most important parameters pertaining to the 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.

how do you reset a charger that was an onboard charger for a 36volt floor scrubber,the charger doesn’t charge , just flashes a few times and pauses and continues in sequence but doesn’t charge the new batteries.
Jim – Sorry for the belated response. Hopefully you have gotten this issue sorted out. If not, the basic way to reset the charger is disconnect from AC power for 60 seconds or so, also being disconnected from the DC side of course. It actually sounds like the battery charger is not picking up voltage from the DC side charge receptacle. Check all connections now that new batteries have been installed. Many times installers will miss a few of these smaller wires that go to the golf cart battery charger charging port.
This is an assumption based on your statement that you have new batteries (which means you have good voltage). Usually these chargers act up when proper voltage is not available to kick the battery charger on.
Power On…

I have Trojan batteries 48 volts. The accusense charger has all switches down except number 3 switch up. Isn’t this backwards?
Larry – Thank you for your inquiry. See the article you responded to. You will need mode 4 for T-105 6 volt batteries or mode 5 for 8 volt or 12 volt batteries.

I had our motor rebuilt and replaced all 8 batteries for our 2011 ruff and tuff cart. We have had great service this year, but this last time we took it out we drained the battery down to almost zero. When I charged it up, it quickly lit up the I and stayed there for awhile. After about 4-5 hours I realized it was on IIIIII. After 4-5 more hours I saw it had the (looked like) 80 % light on, but the II was on. what makes the lights go all the way to IIIIII and then back to II.Is this normal or is it telling me to have it checked out by a cart guy. Do I keep charging till the 100% light comes on? Thanks for your help and time. Over the last 10 years we have replaced the gel batteries and another set of Bulldog batteries and now have U S batteries with the rebuilt motor. I`m trying to be a little more responsible with our investment.
Hi Joe. Sorry for the delay in answering. Do you have a voltage meter? That would be a great place to start. You can get them at any hardware store for about $20. Next check the DC voltage across the black and red terminals. That will tell you the exact voltage of your batteries. If it’s a 48v system, fully charged it would be 48 to 52 volts. I suspect it could be your voltage gauge on the cart that is broken. Please give us a call and we can work through it with you.
