Here is some info on battery ratings that might help you.

"AH (Ampere-Hour) Ratings
6 Hour vs. 20 Hour Ratings:
Rating a battery over a longer time period always means a lower current draw over a longer period of time. The lower the continuous amperage during discharge, the more efficient the battery becomes. The opposite is true when the continuous current draw is increased.

· Forklift applications usually use the 6hr rating."
FYI in Japan and I believe Europe too industrial batteries are rated at a 5 hour rate.

That rating is when the battery is continuously discharge over a 5 or 6 hour period. In actuality a lift truck is not continuously discharged and the time they are used in a single 8 hour shift is much less than 8 hours probably about 3.5 hour meters hour on average high ball operation like break bulk operations (high usage) at ABF, Road Way, etc are about 5.5 hours per 8 hour work shift.
Here is a link for more info.

worked on plenty of this brand
imo they aren't any better than the next brand
every brand has their own set of issues and this brand has its issues just like any other.
as for a 16hr run time?
take a look at the dataplate, most dataplates state an amp hour rate at a specific run time (ie: 843A@6hrs)
Most truck mfg's use a 6hr rate based on a single shift of runtime.
So unless this brand reflects this claim on their dataplate information i do not think a 16hr runtime is official mfg spec.

***smoke and mirrors my friends***

other claims for latest and greatest technology that didn't pan out

i have seen other claims with battery technology where they came out with fast high rate charging systems that can charge a full size industrial battery in 1 to 3 hours and allow for a normal 8hr shift of runtime and then go back and recharge it in 1 to 3 hrs.
Although as attractive as that was for the customer to be able to recharge a truck faster and get it back out on the floor without having to have multiple batteries for a single truck, we found out that during the charging process a battery fire or charger meltdown was a very high possibility so even though it is appealing to the customer to be able to charge batteries faster the dangers associated with this type and method of charging was not as safe as they claimed it was. Plus it is considerably more expensive to buy this technology so most consumers shy'd away from the expense and it is not near as popular.

The trucks are extremely efficient through the motor, controller and system design and easily achieve this guarantee in most applications.

Lol. A customer just bought a Jungheinrich without consulting me. First breakdown and he's already regretting it.

Ah, the "brochure"....always promises the world but, it's all BS.
10 years ago, Wal-mart saw the hydrogen fuel cell brochure, promised 16 hours run time. They got 4, and spent countless hours fixing them. Still not much better all these years later.
Jungheinrich parts prices are out of this world and continent! Their systems are impossible to access. Any possible extended run time will be defeated by downtime...and repair costs.

MCFA does in fact have a "demonstration" tractor trailer going around the USA to prove this claim - this has been going on for a year+. kinda like that big "Idaho" potato commercial (lol). Go to their website and check out their "What New" link. I feel very confident they won't openly share the hows & whats of their test results and some user testimonials are forth coming in their advertising/promos etc.

Anyone got any smarter on this one?

As energy efficient as you get you still cant break the first law of thermodynamics....

As Harry Hill would say!

There's only one way to find out.

Get a demo machine and get them to put their money where their mouth is!

Good explanation!

As a sales rep I know you can not trust publications since they are just fluff and promo material. I would like to hear actual accounts from customers and technicians on real world usage.

Maybe it is with there new battery OPEKE high performance.

I don't understand this either...what about battery degradation over time? In reality Lead Acid batteries only need 80% capacity to be considered 'serviceable', and some start out life near to that 80% threshold (I've done the testing).

Seems like there are too many variables, contingencies, exclusions, limitations, terms, etc. Like buying a used car. To summarize a poster above: Hat's off to Jungheinrich, they've done a great job at marketing.

It it sounds too good to be true...

what is the MAX amp hour of battery you can put in this machine?

I still don't understand how you can get 16-hours run time on a lead-acid without opportunity charging - what about cool down time after full charge - all lead acid batteries tubular or not require a significant amount of time to cool battery at the end heat is what kills the battery.

This promo is legitimate. There are some terms and conditions that must be adhered too but these are either normal battery warranty related issues or some limitations that just make sense which include, needing to charge the battery for a full 8 hours when not in use. You also need to spec the highest rated battery available for the truck from a number of specific battery manufactures. These however are all lead acid high capacity tubular batteries. Some other limitations include using the truck in a non-standard environment that would significantly increase the draw from the battery such as using a clamp attachment. Jungheinrich can support this promo as they have simply designed a truck that consumes power much more efficiently. This is nothing new for Jungeinrich as they have been promoting this ability for many years and are now including some guarantees to support the claim.

Turns out this is not any type of new battery technology just standard lead acid but as they always say, the devil is in the details. There are so many details, fine print, and exclusions on this promotion (ie: equipment can only be used 5 days of the week, must perform a full 8 hour charge after each two shifts, certain battery temperatures must not be exceeded, etc, etc.) that if not followed, void the promotion.

I will at least give them credit for a decent marketing campaign that caught all of our attention.

The 2009 Jungheinrich 4 wheel, 48 volt, AC trucks I work on are the very best I've ever seen in forklifts for battery run time. The first 3-4 hours of use the gauge stays at 100%. Then at the end of the shift it is at about 60%. The 2nd shift guy comes in and continues to use the one without charging for a several hours. After servicing lifts for many many years I vote Jungheinrich electric as the best quality forklift going so maybe there is something to that.

sounds to me like some type of promotion to some kind of new battery technology since that would be the only component that would control how long the truck could run.
I've seen some info out about developments in lithium based battery's and that could be it, but since it does not go into any detail about how they achieve this it's anyone's guess.

I would be weary of this unless i had more detailed information on how they achieve this.

I was reading over the same email promo this morning from MCFA. Very curious as to how this is achieved.

From my limited knowledge the max battery you can put into a 36V 3-wheeler would be ~875AH / maybe ~785AH in a 48V. the claim is NO opportunity charging required either... is the draw/pull from the truck that low or is there some key words missing from their advertisements

Any MCFA dealers who can explain?
