Were there any safety precautions recommended on the acid's packaging? I think normal battery acid is around 37% sulfuric acid--enough to seriously wreck your day if you get any on you. Some folks might want to consider gloves, goggles, and long sleeves for an operation like this.

Trickle chargers are great. Those little motorcycle size batteries only have a good life for about 3 yrs, but if you leave the charger on during all down time, it extends the life for many yrs. Using only one of those cheap ($5) HarborFreight units, my bike's battery is 7 yrs old and still load tests fine without any further maintenance.

Let me second Jake's comment.

At the very least use goggles and gloves. Battery acid in your eyes will certainly ruin your day.

Acid burns on the skin or eyes should be rinsed immediately with clean water for at least 15 minutes. The longer you wait with rinsing, the more time the acid has to do damage.

Preferably you should use sterile but not demineralized water; Damaged skin and ayes are more vulnerable to secondary infections from unclean water. But rinsing off the acid takes precedence over worrying about infections.

I went to the Harbor Freight site looking for one of those trickle chargers you wrote about and find about 12+ models---Please advise what model you were refering to and the model you use? Thank You
