increasing battery life

[Bilge_Rat]

I had noticed that with all ahead 1/3 or even silent running, the batteries were running down very quickly.

However, if you manually set the speed to one knot, you can stretch the battery for a very long time, up to the point where the CO2 level becomes an issue.

(p.s. I'm not using CCIP's battery mod.)

Yes sir! Flank speeds got about an hour out of the batteries. Submerged 1-2 kts got you just about a day. Sure, you got about 80nm over the course of the day but it was not speed they were looking for....they were looking to survive!

Try 12-24 nm in 12 hours going 1-2 knots.

Yup, all us SH3 veterans learned 2 knots will get you easily from sunrise to sunset with reasonable recharge time.

I think a Gato class could stay submerged for 48 hours at 2 knots.. Bilge Rat, did you time how long you could stay underwater at 1 knot?

Those are the stats for a Gato/Balao. 95 NM at 2 knots. My question is could the oxygen hold out that long?

Good question. It's hard to imagine enough oxygen in a cramped sub to last the crew for 48 hours!

no, but 48 hours looks about right.

I just ran a test on SH IV with a Gato in V. 1.1.

At 2 Knots and 24 hours, the battery level and carbo build up are both close to 50.

So it would appear that SH IV models it after the actual specs.

Air scubbers I believe!

I read Gatos onlt got about 30mins at flank speed.

I believe you can say that for just about every WW II submarine.

I read that too.. I'm surprised to hear NEON DEON got 24 hours out of a Gato with 50% battery without the battery mod.. I seem to remember testing it and not getting that long but I can't find the notes I made.

I have 1.1 installed and I went back and tested the Gato five times.

Every time at 2 knots the battery and Oxygen levels were just about 50 and the Gato had traveled 48 NM in 24 hours.

In my version of SH IV, they appear to have it right.

I agree with Neon, the battery situation seems to be good as is.
