clean the cable terminals of the battery cable with a wire brush
(corroded terminals can cause the motorcycle's electrical system
to malfunction!) and then protect against corrosion with terminal
grease. Do not use excessive force to tighten the screws, as this
may distort the battery terminals and damage the battery.

6 | Storage

Store the disused and removed battery in a cool, frost-free, dry and
well-ventilated place, away from flammable, explosive or metallic
objects. DELO AGM batteries should be charged at the latest when
the voltage drops to 12.2 V. In this regard, automatic chargers are
suitable for motorcycles that imitate the charging and discharging
behaviour of a built-in motorcycle battery.

7 | Maintenance

DELO AGM batteries with acid pack have low self-discharge, and
therefore do not necessarily have to be kept permanently on trickle
charge when not in use on your motorcycle. Nevertheless, they
lose capacity daily and must be recharged during longer periods
of disuse. Therefore, removing the battery from the vehicle is
recommended.
DELO AGM batteries should be charged at least every 4 weeks.
If the battery remains installed and connected, your motorcycle's
electrical system may drain the battery even sooner. Ensure,
therefore, that no silent electrical devices are active (e.g. alarm
system, clock) and that no leakage currents are draining the
battery. Discharged AGM batteries can sulphate (crystallise) which
can lead to a loss of performance or even complete destruction of
the battery. As such, ensure that the battery is regularly charged
with a charger that is suitable for motorcycle batteries.
Nevertheless, if deep discharge (under 12 V) occurs in spite of
these precautions, you should use a suitable automatic charger
that is designed for motorcycle batteries and is able to adapt the
32
charging current to the state of your battery. This type of charger
delivers the somewhat higher initial voltage needed to recover a
deeply discharged battery.

motorcycle has been drained by leakage
current or a silent electrical device. Many
modern motorcycles still use power even
when switched off, e.g. for the alarm system,
on-board diagnostics, USB adapter, etc. A
quiescent current of 5 mA is not uncommon,
but it adds up quickly over an extended idle
time. Over 24 hours, 5 mA corresponds to
0.12 Ah, over seven days it corresponds to
0.84 Ah, and over one month it corresponds
to 3.60 Ah.
• Was the battery charged with a maximum
charging voltage of 14.4 V and a maximum
charging current according to the battery
label (10% of the capacity)? A higher charging
voltage or charging current than specified
could have damaged the battery. Check the
charge controller and/or its charger in this
regard.
• If the charging voltage was too low when
charging the battery, it may not be sufficiently
charged.
