Protection for your battery. Thermoil has been treating batteries since 1992. Battery desulfator is non hazardous.




It's designed so that both customer & technician can see the state of the battery acid.
Get the job done with EZRED tools! Battery hydrometer: this battery tester is made to stand up to tough treatment in service stations & garages. Great for use by professional battery techs, mechanics, or anyone else. 300, you can confidently know the state of charge for the battery cell. We specialize in tools for battery, for both the professional tradesperson and home DIY'er! .


300 Flexible rubber tip offers easy access to even hard to reach battery cells while the battery is still in the vehicle. Hydrometers test the state of charge of a battery cell by measuring the specific gravity density of the electrolyte - the greater the concentration of sulfuric acid, the more dense the electrolyte becomes.

Automatic shut-off: battery filler shuts off automatically when the battery cell reaches the proper fill level, ensuring optimum battery performance with no overfilling.
