In our oil plant, we have many Standby Diesel Generators that use 20 cells (1.2V each)of Alkaline acid batteries which are continuosly charged on float mode. Three months ago, we couldnt start one generator because of batteries failure. so until we receive the new batteries (takes 3-4 months)we used two Lead Acid batteries (each is 12V) and showed good performance since then as we weekly start the generator and run it for half an hour. the lead acid batteries (12V, 120AH Heavy duty)are much less in cost but they last around 2-3 years, while the alkaline (1.2V 80AH)acid last 9 years but they cost almost 20 times the Lead acid. So my question is: in the long run, What could be the result of using the Lead Acid batteries instead? If possible, Can you recommend any website that deals with my issue?
