    Posted: 19 October 2018 at 10:07
The two original domestic (house) batteries on my 2016 H445 are failing. I suspect current drain from the refrigerator when the boat is not attached to shore power. Simple question - do other owners have a preferred make of battery as replacements? In addition, has anyone considered lithium ion batteries instead of AGM?

Thanks for any observations

Our 2017 Hanse 455 is being repaired after severe damage from hurricane Irma. It is being fitted for 3 of the Firefly carbon foam batteries (http://www.coastalclimatecontrol.com/index.php/batteries/agm-firefly-sps-northstar.html#!/Firefly-Oasis-Group-31-PSOC-marine-battery/p/95699247/category=25823701) in place of the 2 original house batteries. Given the capability to discharge the carbon foam batteries to 80% or more, this should increase the original battery capacity by 75%.

Original AGMs: 2 x 160 A-h = 320 A-h, 50% discharge = 160 usable A-h
Firefly: 3 x 116 A-h = 348 A-h, 80% discharge = 278 usable A-h

Will begin testing in January.

Many thanks DotandDash

I hope the repairs go well. Must have been a terrible experience.

I'm probably going to wait until the new season (April) before replacing the house batteries so I'd be really interested to hear about your experience in January. That's an impressive uplift in battery capacity. I haven't checked - do the 3 new batteries fit into the space left by the 2 old batteries?

Best wishes


Richard

Hello . and  -,

Do you continue with the Sterling charger ?

All of our electric/electronic components were waterlogged from the hurricane, so it all is being replaced with new componentry from Hanse. According to an online manual, the Firefly batteries can be charged as AGMs, 14.4V bulk charging, 13.2V floating.

Firefly batteries are listed somewhere around $500 USD per battery, but seem to sell out quickly.

The dimensions for fitting the 3 new batteries are within 10 mm or so of the original 2 batteries, so no or only minor adjustments may be necessary to the cabinetry around the battery compartment.

(Note: We are only customers ó We have no financial interest in the battery company or any retail outlet for the batteries.)

We wonít be finishing repairs and refit and doing sea trials until late December 2018 into January 2019, so we will report after that on our experience with the batteries.

AMG can also be discharged by 80% without damage.

Yep, but not 90% or 100%, 80% would be 11.6 Volt. The Hanse fridge has a switch off threshold at 10.5 Volts !!! even 100%:

Yes, I agree that AGMs can also be discharged to 80%, but the number of cycles will suffer considerably
(e.g., 1000 cycles at 50%, 500-600 cycles at 80%)

Thatís also true with carbon foam, but they are claimed to have double or triple the cycle life
(e.g., 3600 cycles at 50%, 1000 cycles at 80%)

In my 455 I have changed from 2x165A AGM to 3x100A Lithium. Did not have to change battery box.
Had to change a charging component from the engine and to re programme the Mastervolt charger.
I am very happy with the result, after 3 year.

Hello Nerthuz

This is very interesting to me. Can you tell me the make of the 100A lithium batteries? And what was the engine charging component that had to be changed? And was reprogramming the Mastervolt charger complicated? Pleased to hear that you've had 3 good years since installation.

Finally, I assume you still have (original) AGM batteries for the engine and (assuming you have one) a bow thruster. Is this correct? I don't know whether the Mastervolt charger can cope with different types of batteries.

Many thanks


Richard
