FULLY AUTOMATIC BATTERY GUARD FLOAT MAINT CHARGER with precise CPU-like voltage and current regulation.
These units ARE NOT Trickle Chargers! They are precision Float Maint Chargers.
Doesn't drain your battery down like other float chargers will if the 110VAC EDISON power source should fail, or if it gets turned off by accident. It has an LED ON indicator as a reminder.
Footnote here - The LED ON indicator will draw a small amount of batt DC current in this AC power loss scenario, so it's always a good idea to remove any charger type from the battery source just as a precaution. That way the batt under Maint Float charging will always be at peak capacity.
It has Reverse Polarity and Over-temp protection, as well as short-circuit protection. The BATTERY GUARD float charger is precisely regulated at a stable 13.5-13.6VDC maximum output float voltage, and WILL NOT overcharge or damage any VRLA (Valve Regulated Lead Acid) size AGM or GEL CELL batteries. Note - Both these batt types are totally sealed, and cannot nor should not be serviced internally for any reasons!!
However, standard flooded lead acid batteries to be charged (whether Deep Cycle or Maint Free types) always need to be first checked and serviced internally ONLY WITH DISTILLED WATER for proper water level, as long as the service caps can be removed to do so!
FREE SERVICE TIP HERE - NOTE - Almost all Maint Free & Deep Cycle flooded lead acid batts can have those so-called sealed service caps torn off and replaced with standard serviceable batt caps taken off of any old discarded batt - just make sure you remove any & all small plastic (locking tab parts) that break off and fall into the batt cells. Use a MON-METALLIC plastic pair of forceps to remove the floating pieces by rocking the batt back and forth until all floating pieces are removed.
As an example - I once took a factory 36-month supposedly "Sealed Maint Free" type batt and replaced those locking service caps with the serviceable type caps, and I got over 52 total months of good service life out of that batt after it showed signs of supposedly being bad at or near that 36-month mark. Only problem with the batt was that the "water level" had gone down slightly below the top of the lead plates and thus lost it's capacity. Perfectly good batt - as no real damage or harm was done, and by adding distilled water to the proper level the batt went 52 months instead of 36 months!! That's what they don't, or more properly WON'T tell you when you have your weak batt checked today!
That was a FREE TIP from me! Enjoy!
The BATTERY GUARD will constantly monitor the battery self-discharge current needs, and it automatically regulates the float current from a required design spec as low as 2ma (or near zero state) up to a maximum of 525-650ma at initial FLOAT CHARGE STARTUP depending on the battery (to be float maint charged) state of discharge. It will charge all types of 12VDC batts only - including all FLOODED LEAD ACID (whether Standard or Deep Cycle types), AGM, GEL CELL, and others for either home, car, motorcycle, RV, or marine applications. Just plug it in and forget it's there! Just that simple.
Btw - My 2 home Battery Guard float chargers are now going on over 10 years old, and they both work just as great today - to perfect specs I might add - as they did 10 years ago when I first got them.
Footnote here:
I also modified one BATTERY GUARD to keep my 14.4vdc Black & Decker cordless drill battery pack properly maintained while it's not being used. The standard battery charger that comes with the cordless drill tends to overcharge it if left on too long. It worked GREAT!!
The reason I said it WORKED (as in past tense) great is because I sold that B&D 14.4vdc cordless drill set-up, and now have upgraded to a Ryobi 18-volt system which I like much much better! More power and more torque! Plus the stock 18-volt Ryobi "fast 1 hour charger" is 2nd to NONE as to it's internal electronics! VERY WELL BUILT! Enough said there.....and btw I kept that modified BATTERY GUARD float charger just in case I ever need it for a 14.4 volt application.
Continuing:
All flooded lead acid batts should first be properly topped off ONLY with distilled water prior to being hooked up to the BATTERY GUARD.
If intending to leave any car/auto/marine type FLOODED LEAD ACID battery types on the BATTERY GUARD, or a FULL-ON HIGH RATE AUTOMATIC HOME/AUTO TYPE CHARGER, for years at a time, I would suggest first adding (installing) a cell hydrogen-to-water converter to each cell to recover water loss. Usually you only have to add these in 'battery bank systems', or multiple battery groups where multiple batteries are being charged from solar (PV) photovoltaic or other recharging sources, such as wind generators, or hydroelectric generators where they are being used purely for inverter backup power.
I would also recommend first fully charging any intended battery(ies), to be stored or FLOAT MAINT CHARGED, with a home/auto FULLY AUTOMATIC TYPE CHARGER similar to say an analog type SCHUMACHER model# SE-520MA, or their newer SC-1200A FULLY AUTOMATIC SPEED CHARGER which is a CPU processor controlled switching type model. The latter having a de-sulfation mode if your battery is indeed sulfated to start with. Nice feature!
The WALMART model # is WM-1200A and cost is roughly $42 + tax. It works flawless and to perfect AGM battery specs I might add. I can also use it as well on all my other car/motorcycle type flooded lead acid batts because it is a FULLY AUTOMATIC selectable type charger for under $50. WALMART, SEARS, and other stores sell them as well.
I also have just recently added on a brand new Heavy Duty Schumacher "made for Sears" batt charger - Model # Diehard 71225 - that is also a CPU processor controlled switching type taper charger selling for approx $80. After testing and using this charger extensively with small (7ah) to large (100ah) size AGM batts I like it even better then my SC-1200A charger. The Sears Diehard model 71225 is now "my personal best choice" overall, and I will now be using it as my #1 choice in all my day to day batt charging applications!!
When I say it's a Heavy Duty charger - I mean just that.
These are my 3 personal charger choices, which I use to recharge all my AGM type 12-volt batts including those that I use in my under-h2o diving equipment, and those larger AGM type batts that I use for all my computer UPS units as well.
That latter 71225 Sears charger will also charge 6-volt batts as well - if I need it to. But it does so much more that I can't even begin to list everything here - so you will need to research that part for yourself either online, or in a Sears store near you.
You can email me if you need more specs or answers to any related ??'s regarding batteries or chargers, as I have an extensive background in ELECTRONICS REPAIR, as well as battery technology and design work using all types of batteries, as well as chargers for same.
THIS FLOAT CHARGER I'M SELLING HERE IS ONLY INTENDED TO CHARGE ONE 12-VOLT BATTERY OFF OF ONE FLOAT CHARGER. PERIOD!
IT WILL NOT CHARGE ANY 6-volt BATTERIES!!
It is solely designed however to provide just enough output charging current regulation to keep your home, boat, car, motorcycle, solar, and RV 12vdc batteries freshly topped off during extended periods of non-use. Again, charging one 12-volt battery at a time per BATTERY GUARD that is!
It CANNOT and SHOULD NOT be used to try and maintain or recharge multiple, or parallel, 12-volt battery arrays. It is designed for and meant to maintain ONE 12-volt battery at a time and only ONE 12-volt battery!
BATTERY GUARD float charger has a precisely regulated 13.5-13.6 volts DC maximum output voltage, and has an initial maximum startup output current of 525-650ma, that drops down to a perfectly regulated 2-3ma maintenance float current, which replaces the internal self-discharge current of any FLOODED LEAD ACID, AGM, GEL CELL, or other similar type battery rated at 12VDC and 5-185Ah.
I've done extensive testing/monitoring using these chargers on AGM type batts, and the results were very, very impressive. GREAT performance for a charger costing only $25.90 shipped, and that which I would compare far superior with others such as say the QUEST model costing $35 or more in auto and marine stores.
I've sold countless numbers of these chargers to date and have NOT had a single one fail yet! So I guess they speak for themselves!
I myself personally have run the same 2 BATTERY GUARDS 24/7 on my 2 DACOR underwater dive scooter YUASA 24ah 12vdc AGM batteries that were going on 9+ years old, and they still carried a great charge that got me 1 hour or more underwater scooter run time!!
My underwater scooter motor current draw is approx 20 amps FULL ON under tow load too! I kept telling myself it's now past time to replace them with NEW batts, but with the proper care it's not impossible to get 10+ years use from an AGM type battery. You just can't beat this BATTERY GUARD price and quality as compared to some other supposed AUTOMATIC FLOAT CHARGERS costing twice as much!!
As of DEC 2007 I've since sold both those 9+ year old batts to a friend of mine, and replaced them with brand new ones of the same brand name. Those 2 old Yuasa batts are still working just fine so I'm told!
I'm also working on spec'ing & stocking 2 more small battery chargers that are going to be fully CPU controlled, and will be in either 12-volt & 24-volt model formats with a 2 Amp output MAX. They will be mainly intended for all the kids motorized scooters that are out there in today's market.
I will also be open to repairing your old defective chargers (if they can even be repaired), and/or upgrading your old charger's wire connector plug-ins to fit my new CPU controlled chargers. There will be NO CHARGE for the repairs if it's deemed your old charger is indeed NO GOOD. You will just have to pre-pay the shipping both ways is all, and I will be working out a blanket shipping cost in the very near future.
Watch for my NEW AD with details on my new SCOOTER chargers! Coming very soon!
