Re: Trik-L-Start start-battery charging combiner

One thing to mention is that if you have gel cell house batteries which are charged at a maximum of 14.2v (Trojan Battery recommends 13.9v) and flooded cell or AGM starting batteries the Trik-L-Start may not supply sufficient voltage to bring them up to full charge and will never desulphate them. Lead acid batteries need higher charge voltages. Optima recommends voltages up to 15v. for the spiral wound Red Tops, which I have, and Trojan 14.7v for parallel plates. Not a concern if you drive the coach occasionally as the alternator will produce the higher voltage. It is a good idea to measure the voltage at the starting batteries as there may be a voltage drop from long wire runs if the wrong wire gauge is used as well as losses caused by diodes in the system. If you suffer from weak starting batteries after sitting for a while with just the Trik-L-Start in use you may want to do that. Remember that the colder the battery electrolyte the higher the charge voltage needed. Desulphation of AGM and flooded cell batteries is also needed to prevent stratification of the electrolyte as well as to remove the effect of sulphation of the plates.
There is a lot more to batteries than meet the eye but keep them fully charged and desulphate the flooded cell and AGM ones occasionally with a good charger and all will be well.
