TROUBLESHOOTING
Check each cell with a hydrometer before and after charging to determine it batteries are weak.
Do not charge or use batteries when the liquid in any one or more cells measures less than 1
.150 specific gravity. A fully charged battery should read 1.270 or better after cooling 1/2 hour.
Batteries that have been properly charged and still do not reach a full charge should be
discarded. One defective battery can weaken the other batteries. Replace the defective battery
if the battery pack is less than two years old. If over two years, replace the entire battery pack.
Daily Battery Maintenance Precautions
1. Add distilled water only.
2. Never add acid.
3. Keep vent caps tight when operating.
4. Keep battery tops clean and dry.
5. Keep water level 1/4” above cell plates.
6. Keep excessive heat and metal away from batteries.
7. Use TORNADO charger with correct voltage and current rating.
