5worth the money if you go through several batteries a year
By S. chandler
i have 4 wheelers tractors tillers and all kinds of equipment that are used only part of the year - the batteries constantly go bad from non use or not being charged enough - i purchased this charger and it repaired 3 bad batteries and is currently charging the rest of the - the only problem i wish i would have solved is finding enough money to buy the charger like this one that will do 12 batteries at a time - it works and its great to leave on the equipment while its sitting - no more dead batteries here and no more having to buy new batteries

5Pulse Tech X2 - 2 Station charger
By G H
I have tried a variety of chargers. This is one of the best around. I have three of these chargers in various locations. I hook up all my vehicles and spare batteries when not driving to keep the batteries at optimum condition. (One should always keep Lead-acid type batteries in a fully charged state, and never fully discharge them.)

I also used this to bring some of my older batteries back to life. For example, one of the older batteries would only register 12.6V when charged with a conventional charger, and quickly settled to 12.1 V at rest. After 4 days of pulsing, the battery is at 13.2V fully charged state, and 12.8V at rest. This battery can be used to help neighbors jump start cars, and it runs some 12V devices effectively during power outages.

Warning: Do not connect this to a bad battery that has a short. The battery will draw current at a high rate from the charger, and the charger gets very hot. Although I caught it in time, it m ay overheat and damage the charger. Always monitor the charger for a few hours when hooking up to an old battery, to watch for over-heating. Or test to determine that the battery does not have a short before hooking up.

I am also using this to try and maximize the life of the newer AGM batteries. We'll see how that goes.

5Odd application, but working fine !
By popauld
Convinced by the concept of distributed battery equalizing or charging, to put it simpler, I decided to use this unit to improve things in my home UPS. This is an old APC 1200VX for which there is ABSOLUTELY no technical support (I guess because of its age, and because APC is more interested in selling new equipment than supporting what they call obsolete stuff).

My UPS is a great design. I have run oscilograph tests of its transfer from mains to battery backup, and it is flaw-less. The output is sinusoidal, or as close as possible without actually doing an analysis. And it is really sensitive to supply fluctuations that I don't even perceive.

However, I found the charging voltage, among other operating parameters, were not quite right. An exhaustive search on the internet turned up absolutely nothing (apart from APC's attitude). I attempted to identify different adjustments, and managed to readjust the transfer level (when the UPS decides that the c ommercial voltage is unacceptable, so as to activate the inverter).

I tried adjusting what I thought was the the charging voltage control, but to no avail. See. it's not really easy to identify which anonymous pot does what.

I had installed two new deep-cycle batteries from the same manufacturing lot - rather than the original on-board VRLA's - and was appalled to see they didn't level out in voltage. One took on a notably higher voltage than the other, obviously starving the brother in the process. Several attempts with a resistor in parallel with the "stronger" battery only helped momentarily.

I installed the dual charger.

Initially, I could see that one or other battery would be on charge, then the other. After a while it levelled off. The terminal voltages are now equal, at about 13.7 volts. The pulsing goes on, and no problem. I never see the charger function activate, unless that is there is a supply problem. Then each charge r takes charge of its asigned battery. Nifty!

I should mention that the UPS has a built-in charger, designed to charge two 12-volt 26Ah VRLA batteries in series. State of the art thought has is it that you should really try to charge on an individual level when at all possible. Like, charge each 12-volt unit on its own, which is what I'm doing. Others have invented devices that drain off from one battery to up the charge on another. I am still studying this, but the idea is the same, basically.

The original APC charging circuit is still connected, but the X2 is connected to the individual (deep-cycle) batteries, sort of in parallel. There have been power failures, and I have seen the X2 react by recharging the batteries, probably better than the APC charger could ever do.

This is my argument. I am still studying the pulsing effect, and hope to rig up a recorder of sorts to see what is actually happening. Depending on voltage and current level s (especially in the pulsing), I may use a Flukescope, and/or a Megger PA-9.

Oh, yeah: Just bought a single charger unit for other needs. I guess I am convinced ... but I will continue to study this.
