Trickle Charging Rolls Surette Solar Batteries ?

Hi There!
I have 40 Rolls Surette (24x 2OS33P and 16x 6CS25P) coming in a few weeks to my current location. They will be used to make 3 separate banks for 3 separate solar systems. They will be permanently installed in the January-February 2019 at their final destination. They will leave my current location with a transit time of 2.5 months to their final destination (meaning, they will be inside a shipping vessel 2.5 months traveling the Oceans)
Questions:
1. Advice on what to do to keep them healthy and charge up till they are shipped out to their final destination
2. Any trickle chargers for renewable solar batteries out there ?
3. I can put a load on them and discharge them (DoD = 0.30 ?) and then recharge them every other week ?
Thank you very much!
PS: Here is one of the setup:

Always minimize the time a lead acid battery sits at less than 100% charge. And IMO, they rarely need to be exercised (ie, I wouldn't discharge them for no reason).
Do charge them fully and keep them charged. IMO, continuous float charging is slightly better than monthly charges.

Tmp..,
You should ask the supplier to have the batteries Crated at Surrette, for shipment.
Have you considered getting these Flooded batteries shipped DRY ? Dry batteries should have a "shelf life" of about one year, or more. This is not an uncommon request for Surrette.
FWIW, Vic
It might help in some cases to keep the weight balanced within the container (ie, don't put all batteries in one end so that it tips when the crane lifts it).
