Loss of fuel efficiancy!?!

Well it looks like the third time is the charm. For some unknown reason for the second half of this cruise I have to turn the "recharge batteries" button off every time I surface dispite never being damaged this cruise and having 100% battery charge.

My biggest regret is an entire night (I dont get nearly enough) wasted trying to sail accross the pacific... real life is a bitch, i want to play computer games

Uh use time compression. Press the + or - keys on the number pad to increase/decrease the time compression amount. And as I said when your charging your batteries you use fuel, so you need to take that in to account on fuel economy. If you dont like the fuel/battery limits simply untick them in gameplay options.

I will try to make this clear while trying to not be a jerk. I understand how to play this game, I play at or near 100% realism. I understand all the finer points of fuel management and battery reacharge. I also understand how to use TC but with the constant planes flying over and framerate limitations due to my computer (8000x is not any faster than 1500x for me) coupled with the fact that I cruise at 9.5 kts, three full trips accross the pacific takes up a very large chunk of my night.

In this particular case I believe a glitch is causing extra engines to be run to charge my batteries at surface even though i already have 100% charge and I NEVER incured damage to my sub, let alone batteries. This has cropped up only once for me in all my in game time.

I believe my problem was outside of the normal scope of fuel consumption/ battery recharge

Thank you for your time and help

Do you also understand that when you dive you can go to all stop...not drain your batteries...and therefore not waste fuel recharging when you surface and resume course ? Do you understand that battery recharge needs to be turned off eveytime you surface? Do you understand that repaired damaged batteries will not always recharge 100% and continue to recharge,thus waste fuel, until you turn off recharge?

If you have trouble making it from Japan to Midway with a 60% fuel range remaining then there is something definitely wrong with your ship handling. I do it rountinely at Ahead Full...even Flank at times ...forget 9 knots.....I save that for patrols when I'm down to 20-30% and need to get back to Midway. Sometimes I have to head south to refuel before I RTB via Midway or Johnson's Atoll.

Also this....

three full trips accross the pacific takes up a very large chunk of my night.

LOL...3 trips across takes up a huge chunk of my week...if you are trying to play a full patrol in a single session then...no wonder....

That, in fact, is why my latest career is Asiatic fleet. I got tired of spending 1 of my 2-3 play sessions per week in transit. Now, I still spend 1 play session in transit, but that's because I'm transiting through a target-rich environment. Not 2000+ nm of empty ocean.

I posted a reply after reading only the first post, so I thought you'd suffered some battery damage somewhere along the way. It's acting as if you did. So, you're going to have to manually turn it off every time for the duration of the patrol. It'll be fixed when you get back to your home port.

As Quillan said

Did you recieve any damage and then repaired it?

There is a 'bug' where if you recieve damage to the batterys and later they appear to be repaired to 100% yet will only take on some percentage of full charge. Lets say 90%.

This causes your battery charging system to run continusually wreaking havic with your 'milage'. To stop this you have to manually select 'normal propulsion' after every time you dive. You can check the battery charge state by hovering the cursor over the 'gauge'.

This is the most likely scenario as fuel leaks are not modeled in the game.


Also when going submerged for whatever reason cut your speed to ahead slow. That way you can run for several hours without totally draining the batterys and therefore taking less time to re-charge.

I had the same problem.
And yes it was a battery thing (recharching up to 99%) and yes manually canceling auto-battery-charge really helped BUT...
it was not always the case. There were some cases were I felt that the problem was weather conditions. Making 10 kts with an opposing storm that lasts days isn't the same as making 10 kts in swimming pool conditions fuelwise, at least in Real Life! Maybe this is also somehow included in the game engine (which would be a great for the devs, by the way!).
Anyway, I got transfered to Fremantle and as the war progresses (now I'm in Spring '44) you also get some forward refueling posts, much closer to the action!
Life is so much easier when you're winning the war!
