Type of Batt charger

To accomplish maximum charging for lead acid batteries it appears that a MANUAL charger of sufficient amps is necessary to attain a maximum charge (per handybob's blog). How many of you use smart chargers vs a true manual charger and what is the life of your batteries. I'm presuming since this is the "boondocking" section that some period of time actually spent boondocking is necessary to comment.

We have a Progressive Dynamics converter and a Morningstar MPPT solar controller. For our Lifeline AGM the 14.4V is correct, the difficulty is that it tapers off Once it hits 90%. You can however using the pendent set it to 14.4V manually. The Moringstar controller is arguably the smartest and since a solar panel is always attached it keeps the battery at full charge. I do monitor the DOD with a Vectron battery monitor.

I recently picked up a Schauer 15 amp "Smart charger" at Walmart to allow me to fully charge and equalize my batteries. (The factory charger tops out at about 14.3 volts, which leaves the batteries less than 100%.)

I'm glad I disconnected the batteries and monitored with a good voltmeter. 16.3 volts is enough to hurt the batteries and possibly fry some electronics.

Just sayin', never trust new equipment.





I installed this voltmeter on the dash and have it plugged in to the power outlet. It allows me to constantly monitor the house batteries. Sixteen bucks at Wally World.

Lead acid and some AGM batteries need to be charged to 14.8v to get fully charged. Maximum recommended charge voltage for a 12v pair of my 6-Fullriver DC224 6v AGM house batteries is 14.9v. I have my Magnum Energy inverter/converter set for 14.8v and my Blue Sky SB solar controller the same.

The home solar community has tested and proven anything less than 14.8v will not fully charge a lead acid battery bank.

It is best to use what the manufacture recommends. Concord/Lifeline recommends 14.4 at 70 degrees. Trojan 14.8.
I called one of the engineers at Concord and discussed the Progressive Dynamics converters, he highly recommended the PD.

We have a Xantrex Freedom 458 2000 watt inverter/charger/converter. My Interstate U-2200's lasted 9 years and still doing OK but I decided to change them as were were leaving on a two week vacation and I didn't want them to fail while we were on the road. The chassis batteries were changed about a month earlier and I suspect they didn't need it either as I just had a bad starter changed and it had the same, no start, symptoms even after the battery change. I went from two 950 CCA to two 1000 CCA batteries.

Something that is good is a temperature sensor on your charging device. My Magnum inverter/converter will go to 15.4v at freezing and so will the Solar Boost MPPT solar controller. I thought something was wrong the first time I saw those voltages on the monitors. A phone call to both manufacturers told me that is how they are supposed to work with temp sensing.

Our Freedom 458 has a temp sensor that uses double sided tape to stick to one of the batteries.
