ACDelco... very unhelpful
I have been trying to get information from ACDelco regarding their
recommended charging voltages for their Voyager M30HMF batteries. I have a home designed/built multi-stage charger that I can tweak to be totally optimal for any battery. I though rather than use the standard values (or range of values) talked about for sealed lead acid batteries I would do some tweaking. The only answer I got back to a detailed question about bulk/absorbtion/float currrents/voltages and the considerations I should program in for battery temperature was "13.8 volts for charging/float". This was after an initial attempt to fob me off with "that information is confidential". I should point out that these where not my choice of battery in the and based purely on their responses to my questions I would certainly not consider buying them again. I guess if you want good batteries, don't buy them from a car manufactures (ACDelco is General Motors). Does anyone have any real info for these batteries? Are other manufacturers more forthcoming with information? Thanks |
