Appendix 3: Battery safety sheet
Battery recommendations
The following chapter provides recommendations for, safety and maintenance.
Safe use of batteries
Below are recommendations for usage and maintenance.
BEWARE!
-
Explosive gas is created while the batteries are being charged, therefore no
fires, naked flames or smoking are permitted!
-
Charging should only take place in well ventilated spaces!
-
The battery fluid levels must be checked at least once a month! The battery
fluid must be at least 1 cm above the level of the plates
-
Top up batteries with distilled water (demineralised) only - always wear
gloves!
-
Always top up the batteries AFTER charging and never fill higher than the
level marker in the cell opening. (see also the instruction sheet for traction
batteries)
Recharge "during operation!" before the BATTERY STATUS screen indicates 50%
discharge should be avoided. Always try to match the approximately 10% discharge
status. Charge a discharge battery always straight on, this will increase the life span
considerably. Therefore, check the acid gravity at least every month with a hydrometer
(Fig. A + B and table below).
The specific gravity of a fully charged battery should be 1280 g/l:
Before charging, switch off the
METO-SWT
with the
emergency switch. When charging batteries, always
connect them to the charger before switching it on. After
the batteries have been charged, switch off the charger
first, then disconnect the batteries.
Overcharging can cause damage to the batteries through
boiling the battery acid dry.
It is advisable to use a modern battery charger with an
automatic cut-off - these are available from Berg
Hortimotive.
Only use a charger type that is suitable for
the batteries being charged! (see charger instructions)
The charging process should never be interrupted -
charging should be completed - see the charge indicator.
