WARNING BEFORE USING
Initial capacity
As all lead-acid batteries, after production, UNIBAT batteries do not offer their full storage capacity
(initial capacity 90-100%). Their full capacity only will be reached after few cycling of full charging (it
depends on the using frequency during the first 6 months).
Imperative charging after deep discharging
Be careful, it is hardly not recommended leaving a lead-acid battery in deep discharge state
!
more than 24h. To avoid damaging your battery in an irreversible way you absolutely need
to recharge it at 100%.
Overcharge prohibited
!
The charge does not have to exceed 15V. An overcharge can damage in an irreversible
way the battery and cancel the warranty.
Maintenance free battery
UNIBAT batteries have VRLA technology (Valve Regulated Lead acid). There is no need to
add liquid, that is the main difference with liquid lead batteries. UNIBAT batteries are
!
completely hermetic. If you open the battery you cancel the warranty.
Bubble and/or crackling during charging
Crackling or bubbles is a common phenomenon on all technologies for lead batteries (Liquid, AGM, GEL).
It is caused by the current going from the electrolyte of positive plate to negative plate. It often appears
at 13.8V, and it is intensified by the current and or by some charging curves with throb charging steps.
This noise is more intense during first charges: it is when the battery increases its capacity. It can be
softened with time.
Warning: the same phenomenon can also come from a charging issue. It is the case when the noise is
present with tensions higher than 15.5V. It is a problem from voltage regulation or too powerfull charge
from your charging system (alternator/ battery charger, solar...). If it happens, disconnect your charging
system and make appropriate corrections.
