I started on my electrical upgrade today. My shiney new batteries arrived. Mate are they heavey. 55Kg each, sorry I don't know what that would be in pounds, but they took some lifting on and into the boat on my own.
I was hoping to have found the manufacturers name on them, but only the NZ importers name was on them. I guess they are either made for the importer/retailer or he has removed the actual name and put his on. So sorry, all I know is that they are made in Germany. They arrived in NZ dry and had the acid added here and then charged.

On there website, they do go into a little about what makes these batteries special.
Batteries ~ Long life, deep-cycle ~ Genkit Nelson Limited

I am taking the oportunity to rewire all the main battery cable runs. Better positioning of the banks and rerouting the cable will enable me to save a significant amount of cable length. I am also going to change the anchor winch feed from the old way it was hooked up which was to the house bank, over to the start bank. All the battery cables will be run in their very own capped trunking to keep them safe and supported.

121 pounds each Alan. Heavier than a bag of cement (40kg).

Up in this part of the world we would call them heavy and leave it alone. Look nice though. Would yours be the cute 3 cell units in the picture? You could have bought the big ones so it could have been worse! Did you get 4?

Sounds like a great project. I'm heading into winter doing my own projects
as well. I did batteries last year. This year I did barnacles, teak, buffed the hull, renamed, and cleaned winches this year. I sort of miss doing batteries. My back hurts from the barnacles still.

The winches were fun. 5 nice big 2 speeds with 35 gears and 20 tiny springs. I only lost one spring. I was amazed I could get Barient pawl springs at West Marine. Spent the whole budget and bought all new ones. Pawls were fine and good thing as they want $10 US per pawl. The bronze gears were in exceptionally great shape. I'm impressed after 17 years of heavy use with little if any cleaning. I had to use the putty knife to clean them.

Alan, Those are the ones Tubular Plate (Wet) that I mentioned in the other thread. They look great!

Highly recommended by Victron Energy as a cheaper and more robust alternative to AGM batteries, for deep cycle service.

I would get these myself, but their height does not work for my present installation (unless I make a few changes….ooops here we go again)

Thank god they are home.

I have purchased the batteries and sulphuric acid separately. Then filled the batteries in place.

The sulphuric acid comes in soft plastic cube packs that way about 50 lbs each, with a valve and spigot.

Just pour the stuff in and the voltage should be 12.8.

I noted on their website that the thing holds 10Kg of electrolyte, so that is 10lt of liquid, which gives a fairly good indication of the volume of these things.
Yes Paul, four of them. These ones were hard enough to get onboard, without going to anything bigger. I was terrified I was going to drop one. There are no handles, which makes it difficult to pick this weight up.

10 kg of battery acid is 8 litres volume spgr=1.25

I managed to find a couple of Trojan 105's for Boracay at a good price.

The slight delivery driver picked them up from the back of his ute and carried them to the boat, no worries. I had no problems moving them into position.

Should they be heavier?
