27DCs and SG Lag Problems
Here is what I mean. Got two rebuilt 27DCs from Interstate as "Econo Power" models, which means they are whatever brand and type they decided to renew and sell at under half price. So just right fo...

Walmart says their 27DCs are deep cycle unlike their 27DPs which are dual purpose. It is hard to get good info on these things. Their answer guy says, to a question somebody asked:
"The Battery Guru--
The difference between the 27 DP and the 27DC is that the DP is designed for " Dual Purpose" both starting and cycling - it has a lower R/C but a higher MCA than the 27DC. The 27 DC has thicker plates and is a true deep cycle battery, designed to withstand constant cycling. Please see ratings below -
27DP = 800 MCA, 150 Mins R/C and 80 Ahr 27DC = 705 MCA, 175 Mins R/C and 90 Ahr 31DC = 800 MCA, 185 Mins R/C and 105 Ahr.
Thank you !"
BTW, the 27DCs I got are more like the specs for their 31DC, but are in 27 size.
I wonder if putting more AH into the same size "jar" makes it harder to get the SG up. The holes for the 6 cells are quite small in a 27 compared with the three big holes in a six volt and also the six big holes in a 12v T-1275.
