increasing battery life

Bilge_Rat · 04-07-07, 07:32 AM

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?

no, but 48 hours looks about right.

I did careful testing of un-modded battery duration and charging times as well as Co2 in default game. The results are here:

I see no reason to use any battery modification because the default game is easily within reasonable historical values.

Hey PV thanks much for the link. My having no familiarity with what's the baseline for such as battery performance on a sub, it looks like a great resource.

Having just started I am having the settings as real as I can stand them and go from there. That and I am really into the historical factors of how they shaped what really happened.

Cheers

I don't think WWII sub had Co2 "scrubbers" in the modern sense. They just sprinkled thin layers of Lithium Hydroxide out of canisters onto shallow pans and plates and distributed them around.
