RX7 2RTR- 1308cc 1.3L Turbo FI (1989)
Current manufacturing techniques enable battery makers to isolate one cell from the other. This process is accomplished by using containment envelopes
as shown (Type B).
INSPECTION PROCEDURE
1.
Inspect the battery terminals and cable ends for white crystal deposits. Clean if necessary.
2.
Inspect vent surface for acid deposits. If deposits are found, clean the surface. If excessive amounts are found and cannot be properly
removed, replace the battery.
CAUTION:
^
Battery electrolyte is a sulfuric acid solution. If spilled on painted surfaces, clothing or skin, rinse off immediately with water.
^
Always wear safety goggles or face shield when servicing a battery.
CHARGING PROCEDURE
Recharge an MF type battery at a rate of 20-30A for two (2) hours.
NOTE:
Most battery chargers require a boost range settng to obtain a sufficient amperage. [20-30A x 2 hrs = 40-60 A/H]
CAUTION:
^
The battery must be removed from the vehicle and put in a well ventilated area.
^
Do not expose battery to fire, sparks, cigarettes, etc.
^
During charging, make sure cells do not begin gassing (boiling) violently. If so, reduce charging rate.
^
Wear safety glasses while checking battery conditions during charging.
^
When charge is complete, disconnect in the order described below.
1.
Turn off battery charger main switch.
2.
Unhook negative clamp from negative terminal.
3.
Unhook positive clamp from positive terminal.
TESTING PROCEDURE
NOTE:
Use Sun made equipment (VAT 40) or equivalent, 1. Apply a load three (3) times higher than battery capacity.
