Hello all from Atlanta! My grandmother has tasked me with selling her 2005 G2. It’s not in bad shape but the batteries are original. My question is should I replace the batteries before I try and sell it or leave it as is? You can drive the cart just fine there just isn’t any real “go” available. I have the knowledge (aircraft mechanic for 31 years) and a good source for the batteries. So is it better to say “With NEW batteries” as opposed to “Will need new batterie”? Sincerely, Dave. ---

Suggest new batteries. MAKE SURE they are at LEAST.t size 31 DEEP CYCLE and you MUST change the charger Algorithm to the type batteries you install. I REPEAT MUST CHANGE ALGORITHM TO FIT TYPE OF BATTERY. 31DCM OR 31DCMJ are $96 each at Orilleys Plus 10% off for veterans… Thse are flooded and charger needs to be set to #13 ---

Thanks so much for the super quick reply! I just took one of the batteries out. It’s a Deka Dominator Gel Extreme Deep Cycle 8G31DTM. Sincerely, Dave. ---

Be very careful when you do this. When you get it done and take it for a test drive you may get addicted and decide to not let the car go!!! Mom will come after you! ---

Take old houseboater words as the best advise you can find on GEM cars. ---

Just wanting to verify… The algorithm that’s on the Delta Q is a 14. Is that the correct one for Deka Dominator Gel Extreme Deep Cycle 8G31DTM’s? I just looked through my grandmothers paperwork and the batteries were changed in 2015 from what kind of battery I do not know. The 8G31DTM was what I removed. I’ve installed 6 new 31DCM’s from O’rielly’s as per Old\_Houseboater’s suggestion. Just curious about the algorithm #14. Once again, just wanting to verify that I need to change it to #13 for the 31DCM’s? FWIW, I do take Old\_Houseboater’s word as gospel. I’ve seen him all over this forum helping. I wish there were more like him on the other forums I frequent. Thanks for all the help. Sincerely, Dave. ---

Here’s what DeltaQ says for my charger. Other algorithms can sometimes be added depending on the model of charger. ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/4/45e21e44d7d19247fe4b85542a2f98820c9662d9.jpeg) ---

Thanks Red. I swear that’s the only chart I didn’t look at! Sincerely, Dave. ---

Thanks everyone once again. I have to say changing the charger algorithm was quite the pain in the keister. Didn’t have any luck with any of the “tap” methods. Finally got it to work when I did step 8 of the Algorithm Selection pdf found [Here](https://support.delta-q.com/hc/en-us/articles/360016476892-How-to-change-the-algorithm-on-the-GEM-charger). It specifically states right at the top that it’s for Pre-2005 Models but it was the only way I was able to get it changed. Red, your chart was spot on. Was able to cycle right around back to 13. Sincerely, Dave. ---

How did the new batteries do? About how many miles can you go or how long will they stay charged? ---
