S Class not recharging batteries

07-18-07, 06:30 PM

If somebody figures out how to fix this, maybe it can be rolled together with the battery life mod.

Simple fix...when submerged travel at 1 knot during the day...works a treat...

The 1200 diesle power for the S boats might be because the S boats had only 2 600 horse power engines. The electric motors were 1175 for the S18 class, and 750 hp for the S-42. (remeber to multiply these figures by two for the full power of the electrics. So indeed the electric motors were more powerful than the surface propulsion.

The porpoise class had 4x1,300hp diesles, and 4x521 hp motors.

The batteries on subs drained quite fast at high loads, and charged quite slow. It did take nearly an entire night's running on the surface at 2/3 speed to charge the batteries. This is why subs were more diving boats than true submarines.

Compared to the German boats, American boats were not all that great, until the advent of the Gato, and Balao class subs. The Uboats could charge batteries quicker, but also had smaller capacity compared to the american ocean cruisers (which aside from the Sboats all american subs of WWII were.).

The charging times may in fact be accurate.

Still, with the lower charge the s-boat batteries hold, a 24 to 36 hour charge time is a bit much.

Agreed Mechman. It takes me more than 24 hours to recharge batteries. Much more if they're below half.

While your points are accurate pythos--and well researched

--this problem is a game bug. It makes the S Class pretty much unusable for a Career boat in my opinion.

Cheers All! I'll buy a drink to anyone who figures out this little annoyance. But I'll want to see some ID to make sure you're of legal age LOL.

I found if I run at slow speed my batteries recharge faster, if I run at flank batteries charge at ~1% per hour.

U-boats could stay under a LOT longer than the American boats could though. U-boat electric engines were probably more efficient than the American counterparts and if they weren't better necessarily, they didn't have to push a boat as large as the American Boat through the water. Even though in terms of batteries, size does matter, its worth pointing out that AFA's batteries were very high quality.

The American boats were far supperior to the U-boat when on the surface in terms of general cruising. Except for the S-boats a VIIC would leave one of them standing.

Still I do like the American subs, they had radar technology which was above and beyond the german equivalents.

How do you figure?

VIIc: 80/4

IXc: 64/4
http://www.uboat.net/types/

Gato: 100 nm at 3 knots (185 km at 5.6 km/h) (maximum) submerged
http://en.wikipedia.org/wiki/Gato_class_submarine

Looks about the same to me.

Most sources give the Gato 48 hours submerged endurance.

Ducimus · 07-29-07, 07:26 PM

Endurance is all about how fast your going. At 2 kts a gato had a 48 hour endurance from all ive heard. Uboats weren't particuarlly superior at anything except deeper diving, and probably submerged turning radius in the type 7 varients.

If i remember correctly In terms of recharging batteries, The Us fleet boats had it over the uboats. Uboats and two direct drive engines as i understand. When on the surface a clutch was engaged the purpulsion was switched where the engines directly drived the props, with the Emotors unused. If they wanted to recharge, they had to put one engine "off the line".

In a fleet boat, the emotors are what always drive the props, what changes is the power source. Batteries, or four diesal engines albiet smaller then the two engines the germans used. But since its an indirect drive, the battery recharge and needs for surface propulsion had greater flexbilty, and its surface propulsion relativly unphased.

Now as to that bloody S boat, ive tried all sorts of funky stuff, about the only thing i ever manged to do, was reduce the battery drain, thats about it.
