Battery With Removable Caps

Requirement
- Temperature of battery must not be less than 10 °C (50 °F)

Tools required
- Battery charger: Christie Automotive Model 400 QDD or equivalent

NOTES:
- Follow battery charger manufacturer's instructions
- Before testing a battery that has been charged, load battery with 15 amps for 1 minute to remove surface charge

WARNING!
- Gases given oft during charging are explosive. DO NOT smoke in rooms containing a charging battery, or have bare light bulbs or any other source of sparks or flame.
- Battery charger MUST be turned oft when connecting or disconnecting cables on battery,
- "Boosting" a sulfated battery at a high charging rate can cause an explosion!

Battery with removable caps

Remove cell caps while charging. If water is added, fast-charge battery for a few minutes after battery begins gassing (boiling).

Slow-charging rate should be approximately 10% of battery capacity (example: with a 45 Amp-hour battery, charging current should be about 4.5 A).

Fast-charging rate should be approximately 80-90% of battery capacity.

CAUTION!
- Batteries may be damaged by fast-charging. It should be used only as a last alternative, when slow charging is not possible.
- DO NOT allow battery charging voltage to exceed 17 Volts.
- If battery begins gassing (boiling) violently when charging, REDUCE charging rate.
- DO NOT disconnect the battery while the engine is running.

- Charge battery according to following table:

Specific gravity Fast charge up to

1.150 or less 1 hour
1.150 to 1.175 3/4 hour
1.175 to 1.200 1/2 hour
1.200 to 1.225 1/4 hour
