Hi Herb and Ben, > >Where did you buy the BatteryMINDer in Baltimore? P& H Auto Electric off of Eastern Avenue and Rolling Mill Road. > Do you plan to use it just for reconditioning or are you >planning to use it as the charger on the boat? Both, one to keep the batteries in the yard equipment from sulphating. The 13.03 volt maintenance trickle will keep the batteries up and the pulse will polish the plates at the same time. The charger circuit is very small so you must have your batteries topped with the big charger first. Most pulse units will work along with your normal charging equipment, the pulse does not seem to care. Most units do not have a charger built in and use the battery's own electric to do its thing. > I would guess that it wouldn't have the capacity to replace the battery charger? The unit can keep 4 batteries up, but it will only pulse ONE at a time. This is the problem with ALL pulsing units - they will pulse only one unit at a time. Even the large military units will only work with one battery. The same goes for 2 6-volt Golf Cart batteries - for some reason, the copper wire connecting the two batteries together will not allow the unit to pulse both batteries at once? So, every few weeks I am going to disconnect (easy because I use flag terminal posts) the batteries and connect them to the pulse units. No water loss, polished plates, and at least doubling the life of the batteries is good incentive. My boat has a "booster" battery in the bow for the windlass and this battery just sits there sulphating away with a normal charger. So, one BatteryMINDer will be connected to it at all times for a factory fresh battery. Also, no gassing (13.03 volts) under the forward bunk where unfortunately the battery lives. >How long does it take to bring a battery back? It takes about 2+ weeks with the little BatteryMINDer. The big Pulse Tech units claim from 48 to 72 hours! The big units are still very expensive so I can wait several weeks to bring the battery back. I am going to buy several more BM and just leave them on and forget them as they will not overcharge or over-pulse the battery. Much safer then equalizing and the plate material does not shed as it does with equalizing. The batteries like a good load on them after pulsing and then they will accept a healthy bulk charge from the alternator or the boat's battery charger. Ben Lewis' post says that he is working on building a pulsing unit. He is correct is stating that we can buy a unit for almost the same cost as building one. We need to have one of the electric gurus take the plans and scale them up so that we can pulse in less time. http://www.homepower.com/download2.htm has the free plans for a mid-sized unit. We need a more powerful unit like the large Pulse Tech units. Anyone out there that can scale up the pulser circiut so that we can polish a big bank all at once?

RE: battery minder. Do these units work for batteries that have been extensively over charged? anyone care to comment?

It seems to desulphate all batteries tied in parallel. =============================================================== >The unit can keep 4 batteries up, but it will only pulse ONE at a time. >This is the problem with ALL pulsing units - they >will pulse only one unit at a time.
