Intelligent Battery Care
Safety instructions.
Keepower chargers can be used to charge
lead-acid batteries only (wet, gel, AGM, Ca/Ca…)
Don’t use them to Ni-Cd, Ni-MH, Li-Poly and other types of batteries.

Battery. Parameters
Nominal voltage [V]
•
6V (3 cels)
•
12V (6cells)
•
24V (2 batteries 12V conected parallely)
Never use 12V charger to charge 6V or 24V battery!
Battery. Parameters
Capacity [Ah]
Capacity says how much energy
a battery can store. Charging current [A]
depends on the battery capacity. Smaller
batteries have to be charged with smaller
charging currents.
Battery. Parameters
Battery types
•
Wet- (flooded) battery- electrolyte
flows freely throughout the battery cell
•
Gel- diluted sulfuric acid is solidyfied to gel
state by adding gel agent e.g. silicon dioxide
•
AGM- electrolyte is absorbed by glass mat
separator placed between plates
•
Ca/Ca- plates and grids contain calcium preventing quick
selfdischarging and rising gas limit voltage
Battery. Parameters
Battery voltage [V] while not used
Measuring voltage on the battery while not used
user can verify battery condition.
12V battery voltage facts:
•
11.8V –deeply discharged
•
12.0V-discharged
•
12.2V-low charged
•
12.4V –medium charged
•
12.7-fully charged
Battery. Parameters
Battery voltage [V] while not used
Measuring voltage on the battery while not used
user can verify battery condition.

Note: The state of charge is an approximation. The relationship between state of charge and voltage vary
by battery condition, battery age, temperature.

All Keepower chargers finish charging
at gas limit voltage automatically.
Charging over the gas limit voltage can damage
the battery. Overcharging is especially dangerous
for the health of gel and AGM batteries.
Overcharged battery produce oxygene and
hydrogen giving a dangerous explosive mixture.
Battery. Parameters
Maximum charging current [A]
To prevent damage the battery should be
charged with current [A] not exceeding
maximum recomended current by the
batteries producer.
Usually the maximum charging current is
bigger for a battery with a bigger capacity.
Battery. Parameters.
Maximum charging current [A]
Charging current can’t exceed „3h” current.
For 120Ah we can calculate maximum
charging current:
120Ah:3h=40A
Using higher charging current we can destroy
the battery (separators and plates) due to
rising electrolyte temperature.
Battery. Parameters
Electrolyte gravity
In batteries with access to cells electrolyte
gravity can be measured by aerometer.
Result gives important information
regarding battery condition.
Fully charged battery has electrolyte
gravity 1.28 g/cm3 (normal gravity).
Not fully charged battery has lower
gravity of electrolyte.
Low gravity (lower than normal) - battery
needs charging.
Battery. Parameters
Electrolyte gravity
Higher gravity (higher than normal)battery lost water by overcharging
(gassing). The Battery can be sulfurized
because of too high gravity of acid.
Separators can be destroyed as well.
Battery with low acidic gravity can freeze
below zero. Battery case can be destroyed
from inside by ice. A frozen battery won’t
work or be charged.

Important things to remember when buying a charger
Do you….
1. Do you want to charge all lead-acid battery
types (wet, gel, AGM etc. ) with one unit?
2. Do you want to charge 12V or 24V batteries
using one device?
3. Do you want to save time leaving the charger
connected to the battery unattended ?
4. Do you want to be able to charge deeply
discharged batteries with voltage 0V ?
Important things to remember when buying a charger
Do you….
8. Do you want to be able to „kick” sulfurizated
battery to start receiving energy?
9. Do you want to be able to keep the voltage on
your car while replacing the battery or without
the engine running (dealer station)?
10. Do you want to verify battery condition
with your charger?
11. Do you want to be environmental friendly
using charger with high efficiency level?
