How can I get the Longest Life from my Batteries?
« on: June 21, 2010, 03:20:05 PM »
The best way to get the longest life from Batteries is not to use them and just keep them on a Float Charge for their entire life. You can get over 20 years of service this way. However we want to use our power don't we, and therefore we want to use the battery. Here are some quick tips on how to extend your battery life . . .

The less you can drain the battery before you recharge it the better
Don't leave your battery discharged for a long time, recharge as soon as possible
Keep the voltage above 12.0 volts as much as possible to avoid Sulfation
Voltage below 10.5 volts will cause Hard Sulfation which is hard to reverse
Do an Equalization Charge regularly to help remove sulfation and revive the battery
Equalization is a Higher voltage of 15.5 to 16 volts for 2 or 3 hours on a regular schedule

Here is Too Much information about taking care of Batteries, their Construction and Operation.

This Do and Don't battery table summarizes the need to obtain reliable service with long life and advises proper handling of each battery type.

Schedule as many loads as possible while there is incoming power, then as far as possible the inverter will draw from the incoming and not the batteries, doing this will limit the battery depth of discharge and lengthen their life.

You'll also generally get much more useful energy out of your system that way, since putting it into a battery and getting it out again loses ~20% (depending on battery type, and balance of system efficiency).

for deep cycle batterys a battery pulse desulfator helps keep the battery alive longer

Sorry, but I disagree.
 
Can you cite some unaffiliated studies that prove this?

Or are we just supposed  to believe you "on faith"?

Please do not make statements as fact without some backup data.

I ran one from day one on my 12 volt Trojan 105 bank of a dozen batteries and it showed absolutely no increase in life. Period.

That is my personal real world experience.

What is yours?

Just facts, please.

In my experience, building some type of enclosure that you can use to keep your batteries warm in winter and not too hot in the summer is really important for getting the longest life out of deep cycle batteries.

I agree wholeheartedly  with the comment about scheduling high loads when you have incoming power.  Another tip is to unplug electronic devices when you're not using them so that they don't draw phantom power.

Two other points for what they are worth.

If your batteries are flooded lead acid, set up a regular schedule to check and add distilled water as needed.  I once had a couple of batteries go below the the tops of the plates, a good ways down actually and they probably were like that for a while, and nothing I tried subsequently restored them to their former capacity. 

Check the battery connections on a regular schedule for loosening or signs of corrosion.  2500 Watts at 12V is 208.3 Amps.  For example, .02 ohms of resistance across a battery connection means that that junction has to dissipate 867 Watts of power if you were actually drawing 208 amps.  I have melted off a few battery terminals on high amp draws over the years, although usually at over 300 Amps in a vehicle application where the additional amperage and vibration aggravates the situation. If the junction is between lead and another metal, in my opinion, it is beneficial to use an anti-oxidizing compound sold for such applications.
