Martin, the kit will last indefinitely. Remove the anodes from the tank and put the lid back on till next time. The only thing to look out for is not letting the electrolyte get to cold, if you do then some of the salts in the electrolyte will drop out of solution and are then a bit tricky to get back into solution. Don’t keep them in the garden shed over winter. The only thing you will need to replace are the nickel anodes as you use them up.
