Deionised water

Keep your battery maintained with the correct chemical additive


Top up your battery to maintain longevity and chemical integrity. 

Flooded lead acid batteries need to be checked regularly and electrolyte levels topped up if necessary. NEVER use tap water! Deionised water is what you use to top up the electrolyte levels and ensure your plates are covered. 

Keep those expensive batteries in good condition and working for as long as possible. So many batteries die an early death from lack of this simple maintenance being carried out. 

Every single Motorhome and boat should have at least one bottle of this on board! 
Deionised Battery Water
This listing is for a one litre opaque bottle of deionised water - this is to keep the sun out which degrades the water. Store in a cool dark place. 

$5.50 1 litre bottle
For larger quantities, please ask and we will let you know shipping options.
