Introducing the most advanced and simple to use fully automatic battery charger on the market today. The AccuMate will assess a batteries condition, recover deeply discharged batteries, monitor and charge, all automatically! Designed for all types of lead-acid batteries, including sealed and gel types, from 2.5Ah to 33Ah capacity.

AS SIMPLE AS 1-2-3!
Just connect to a battery, plug into your outlet... that's it! AccuMate does the rest... optimally, automatically. No switches, no knobs, no decisions... NO PROBLEMS! Next day - next month - next year - your healthy battery will be READY TO GO!

Everything you wanted to know about the AccuMate....but were afraid to ask!!

AccuMate - The automatic optimizer for every 12V lead-acid battery - A comparison.

- How does AccuMate differ from most other small "automatic" chargers?
AccuMate uses the fast, technically advanced combination charging system of constant current followed by constant voltage. Switching between modes is carefully set up to occur at electronically monitored voltage levels. Constant current type chargers like AccuMate charge in the same time as "conventional" constant voltage chargers with nominal charge current more than three times as high. This is thanks to the charge current being maintained at the initial rate throughout, instead of tailing off as the charging progresses as in the "logarithmic characteristic" of conventional chargers. In fact the only reason why nearly all chargers are built on the constant voltage principle is because it is simpler and cheaper to make!

With AccuMate, (unlike most conventional chargers),  it is impossible to over-charge the battery. And even fully sealed, ("MF", Yuasa YTX series), and semi sealed batteries of any lead-acid design can be safely, automatically & optimally charged without an attendant being present. And there is no risk of damage through wrong connection. Short-circuiting will not manifest any spark! It just resets the automatic program to "start." The circuit is automatically protected against inverse polarity connection, indicated by a red "warning" led.

- How does AccuMate differ from other "automatic" chargers?
Conventional chargers, with some form of electronic voltage control, are certainly much better than the majority of cheap chargers on the market. There are even one or two chargers, such as "Battery Tender", offering a similar combination constant current / constant voltage method of charging, as used in the AccuMate, and also offering the advantages of speedy charging followed by float charge maintenance of the battery on an ongoing basis. But, AccuMate's features go far beyond this, as well as using four easily read light emitting diodes (LED's) to signal its advanced features, which are listed below:

FEATURES
- AccuMate can distinguish between batteries which have fairly high resistance (Ohms) because they are full and batteries which have fairly high resistance because they are deep-discharged or even sulfated. In this way, AccuMate avoids misjudging "bad" batteries for "good" and misinforming the user accordingly!... How? ... By Trying, in the first place, to pass only a very small current into the battery. "Full" batteries will still accept such a small current, for the very short time required for the assessment, without significant resistance, whereas a deep-discharged / sulfated battery will still exhibit high resistance. Thus the AccuMate can distinguish between the two conditions.  This is the first big difference.

-  If AccuMate has assessed that the battery is deep-discharged, it automatically engages a special high voltage recovery mode, indicated by an orange LED. In this way, AccuMate can recover batteries which have been allowed, over a long period-even two or three years,   to self discharge to as low as around two volts.
This is a true claim, and we have numbers of testimonials attesting to it!
This is the second big difference.

- Next, if AccuMate finds that after 24 hours of this recovery mode it has not been able to recover, say, a thoroughly sulfated battery, it clearly indicates this by means of the illuminated red LED, but nevertheless automatically continues to "support" the battery with a "float charge" to avoid further deterioration. When the user arrives, he will see the situation immediately and clearly.
This is the third big difference.

- AccuMate is quicker to bring the average battery to full charge.....HOW SO?......
Because when AccuMate goes from constant current to constant voltage mode, it continues to check whether, during the next 30 minutes, that "constant voltage" does stay constant.......Why should that help????.......Because the voltage reaction characteristics of batteries become more and more irregular and spiky the more times a battery has been significantly discharged and  n recharged. So the point at which constant current changes to the "maintenance float charge" mode can be prematurely triggered by random "spike" on the voltage "curve". By continuing to monitor the voltage after the change in mode, AccuMate can detect if it has been "fooled" into switching over too early by such a voltage "spike". And if the "constant voltage" does drift down during the half-hour, signaling just such a   "misreading" of the voltage signal, then AccuMate automatically doubles back into constant current thereby assuring the user of a true full charge in the fastest feasible time. This is the fourth big difference.

- AccuMate can detect batteries with one or more "shorted cells" or internal current drain... Yes really! This is how... If, after 24 hours in the normal charge mode, (that is the full constant current charge), the voltage has failed to climb to the 14.3 V change over point, AccuMate will warn the user of the fact that the battery is failing to reach full charge (which must be due to a shorted cell / internal current drain as we are in "yellow" normal charge mode, not "orange"), by illuminating the red LED. This is the fifth big difference.

- Once AccuMate is sure that the battery has been brought to full charge, it then proceeds automatically to check if the battery (especially when s\till connected on the vehicle) can hold it's charge... HOW?? ... By stopping charging for 30 minutes, and just waiting and watching what happens to the battery voltage... does the voltage stay up ... or drift down signaling a weak or damaged battery or perhaps a leak of current in the vehicles circuit.

If AccuMate detects an excessive fall-off of voltage during this half hour, it immediately indicates the problem (red LED) and will automatically go into float charge support mode.

If the battery passes this test, then and only then will AccuMate indicate GREEN LIGHT for the battery. That way the user is told not just that the battery has supposedly been charged, but also that it has been assessed, successfully recovered from deep discharge where necessary, then optimally full charged and then tested. This is the sixth big difference.

 - OK......these are great feature, but how much extra would I have to pay for them????
AccuMate's suggested retail price, excluding local/state taxes, is $59.99. Considering all the advantages offered by AccuMate through it's "years ahead" technology, this is a very modest and affordable price.

- How come AccuMate can offer such advanced features at such a relatively modest price? And be such a good looking product on top of all that?
Because AccuMate is truly a "world product" produced in significant volume and sold in more than 25 countries world-wide, in both 110/120 Volt and 220/240 Volt versions, with both European and North American certifications, with instructions in 8 different languages and with four different national mains outlet plug configurations. The moulds and product design are fully owned, and integrated to one another,  for a really efficient design and production.

- Warranty & After Sales??
Warranty claims history to date - 0,09% that's nine in ten thousand units. Warranty is 2 years, free replacement, either by product replacement or crediting of account.

- Which Batteries Can Be Charged?
Any 12 Volt lead-acid from 2, 5 Ah to smaller automobile sizes, lead-antimony, lead calcium, "Yumicron" CX, fully sealed MF or GRT types, as well as storage type Gel batteries used in caravans, boats, back up power supplies/generators, etc...
