We got a problem with some of our older trucks boiling due to being put on a too high amperage, from what we can digest anyway. I bleive we need to get a proper class in battery maintenance at any rate. we have sever chargers for 48 volts, including one 150A, and wehn we put a speciffic series of Sichelsmidts on that one, they always seem to boil over, even if we only top up the water after charging (first thing of the day, though not always every day for all trucks..) our latest M970's have had their batteries deteriorate far sooner, compared to our older M9xx's our oldest which is a 03 make, is just now starting to show seriious battery issues, after about 6000hrs, compared to about 2.5k on the newer 06/07 970's


We got a lot of new workers that drive the things as they were stolen, and I fear the fragile crap BT270's we have now, will not outlive our sichelsmidts.
