REES
Tractors are equipped with two 1'2V batteries, Capagjfy
56 Ah {measured at 20 hours discharge) connecieg
in series, to reach the generator voltage of 24 5/,
The main battery characteristics are:
1. Connections, covered with mastic insulating
material to prevent current a'is;Jersiohs and prg.
tect against corrosion the connections and the
pole terminals.
2. Separators, for protection of battery lead plates
from vibrations, made of extremely thin paroug
rubber, or of poiivynil plastics.
3. Self-levelling and splash-proof plugs, allowing
electrolyte self-levelling, and preventing its splash-
ing from the vent. holes, when tracts; jolts in
operation.
Sizes:
— length . . . 368 to 372 mm (f4'4882" t0 l1i.6-455")
-— Width . . . 173 i0 777 i'l'?m( 5.31 l0" to 5.9555" j
~— height . . . 197 to 200 mmf Z7559" to 7.8739")
Battery makes: '
— Marelii 6 TF 9;
- Titano 6 CR 4 F.
Weight (with electrolyte) approx. 24 kg (52'Q10 lb).
Keep batteries clean and dry, particularly the upper
parts, thus avoiding, especially after the recharge,
the corrosion of the element sealing compound,'
smear terminals with pure Vaseline, avoiding the use
of lubricating grease as it reacts with sulphuric acid
of the electrolyte (vapour or liquid).
Electrolyte should completely cover the element
plates, and top-up them of about 5 mm (0.1969").
Distilled water only should be used for topping-up
then make sure the plugs (A, -Fig. 162) are fully
tightened.
For longer battery life, avoid any contact between
water and metallic containers. >
Unscrew the plug, and introduce the hydromeier in
each element; the specific gravity represents the
