Ride the Elk! Do you dare? Send us your photo, which shows you "riding a moose" - regardless of the animal's size, being a plushie or a clip of paper.
If you are visible on this photo, together with your company's logo, and you allow us to publish this picture on our web sites, we will grant you another discount on your next invoice, and this will be at least 100€, up to a maximum of 1000€. We are looking forward to receive your photos!

Furthermore, it becomes much easier to acquire the exact and needed number of licences for the installation version abacus4b. Use packages of five, ten, 25, 50, or 100 licences. Even individual licences for installation are now available. But, of course, our economic "Flat" for an arbitrary number of users continues to be available.

Finally, in our online version abacus4u,for the "shared" licences we are removing the restriction that all users have to be in the same organisation. Freely distribute your single licences now internally or to your external clients. And should you consider "One-for-Ten" too thin, use the new "One-for-Three" or "One-for-Five".

... and, as it will be Christmas soon:
For every order placed until the end of this year, December 2017 will be included free of charge!

... and, as it really will be Christmas soon:
If your order reaches us exactly on December 24^th 2017(e-mail, fax, phone; normal mail on 23^d 2017),
we will give you the whole first quarter of 2018 as an additional present on top:
the first half year's invoice 2018 will be halved!

And of course it can be calculated by the appropriate standard IEEE Std 1568 in abacusIEEE!

... but with stepped profile, too:

And don't get lost - You only need very few downloads actually:

abacusIEEE 5.6 is out!

Many new features are waiting for you in version 5.6

• Graphical presentation of voltage curve according to IEEE
• Enhanced presentation and handling of price information
• Commercial hints for every battery range and cell model
• Minimum order sum and quantity, and minimum order surcharge
• Country of origin for all types and batteries
• Enhanced e-mail security (by using SSL encryption)
• Optimized selection of charge voltage according to IEEE
• More comfortable handling of load profile (copy & paste...)
• Freely configurable standard input by using the Defaults Wizard
• Optional sizing of NiCd batteries without float voltage correction
• Automatic, configurable adaptation of number of parallel strings
• Enhanced, stacked presentation of IEEE random load in profile
• Enhanced document export as PDF and Word-DOC, HTML, XML

Extended support via maintenance agreement will be continued until Dec 31st 2016.

After this date, support will only be granted in individual cases and with valid agreement.

This affects old software versions only.
Database maintenance will be continued!

We want to help you in that and give you the chance to experience this fantastic feeling.

Therefore, we offer a terrific discount of 40% in the first year for every subscription of our online system abacus4u ordered between June 15th and 28th, 2015.
And for the rest of this year, we apply the same discount, of course!

So for the period 2015/07/01 - 2016/12/31 you pay only 90% of a one year fee. It is thus cheaper to subscribe for 18 months now than later for one year only.

Please tag your request or order with the code word MIDSOMMAR and leave the rest to us! We love to share your happiness!

Therefore, battery manufacturers quite often ask: "How can we achieve to be listed in the database of your abacus​ users? How can we, as a supplier, achieve that our batteries will be calculated within the abacus? If we bear the expenses needed to be part of the abacus, will I be listed in yo ur users' versions?"

In this case, there exists a mutual dependancy, for to appear in the abacus, battery data have to be in the system; to populate the database, manufacturers like to be calculated in abacus...

This is why we recommend the following multi-step access to battery manufacturers:

1. You insert a representative part of your battery ranges into the abacus database,
   and we will advertise these data to our abacus4u online clients.
2. The price to populate the database can be calculated from your official discharge data and your wish list for the ranges to insert, but this can be drastically reduced if you do a part of this work on your own.
3. With that, everyone who likes may calculate your batteries, maybe even as a supplement to their offline calculation.
4. You are thus very well equipped, to be seen by our abacus5 clients who normally calculate with their offline version, for we will recommend you accordingly, as soon as you have at least ranges in our database.
5. With that preparation, it is possible to install your database at our abacus5 offline clients on a very short notice.
6. Once your data are available in our system, it is extremely simple, to utilize them for your own calculations, too, and very often the best ratio of price and value will probably be to license the online version abacus4u.
7. With abacus4u, you can do your own calculations as well as “donate “ temporary licenses to your clients.
8. Prices for that start at 49,-€ per month & license and 99,- per month & One-for-Ten -license (or use an annual license, pay 10 months but use one year).

We would love to go this journey together with you and will support you as best as we can in this!

It shows you for every battery model which curves are in the database to calculate it.

In this example, you can see that, for the selected battery model, Kt curves exist for final voltages between 1.60 VPC and 1.85 VPC and that these cover discharge times between 0.02 minutes and 600 minutes. There are also KtP curves for the same final voltages and discharge times, and you find a temperature correction curve for the range of -20 °C to +50 °C.

Vice versa, you can detect for every curve, to which battery models it will be applied.

In this example, for a specific manufacturer a specific Kt curve has been selected, and the Curve Explorer shows to which six mattery models this curve will be applied for calculation.

... and is now called abacus 5 or abacus4u, depending on the question whether you decide yourself for the open company license or an individual online subscription.

Of course, the new abacus implements loads of new extensions and enhancements.
