INTRODUCTION
Congratulations on your purch ase of your new p rofessional M100 Swit ch Mode Charger with
Pulse Maintenance, F loat, Anal ysis and Rec ond. M100 is a member of a family of prof essional
chargers from CTEK SWEDEN AB. It represents the state-of-t he-art tech nology for battery
charging. A M100 will pr olong the lifetime of your batter y. Read this u ser manual and follow the
instructions ca refully before using the charger.
SAFETY
• The char ger is designed for lead-acid batteries from 14–225Ah. Do not use the charger for
any other purpose
• Use safet y glasses and turn your head away w hen connecting or dis connect ing a battery.
• Batter y acid is corrosive. Rinse immediatel y with water if acid comes into contact with skin or
eyes. Seek m edical advice.
• Make sure that the cable is not pinch ed or in contact with warm sur faces or sharp edges.
• While ch arging, a bat tery can emit explosive gases, so it is important to avoid sparks in the
immediate area.
• Always pr ovide for proper ve ntilation during charging.
• Avoid covering the charger.
• Make sure that the elec trical c able does not com e into contact with water.
• Never charge a frozen battery.
• Never charge a damaged battery.
• Do not place the charger on the bat tery while charging.
• The elec trical connection must fulfil th e national heavy curr ent requirements.
• Check charger cabling before use. Make sure t here are no cracks in the c abling or in the
protective covering. A charge r with damaged cables may not be used.
• Always check that the charger ha s gone over to maintenance c harging mode bef ore leaving
the char ger unatte nded and co nnected for long periods. If the c harger had n ot gone over
to maintenance char ging withi n 3 days, this is an indicati on of a problem. In this case the
charger must be disc onnected manually.
• All batteries fai l sooner or later. A batt ery that fails during charging is normally t aken care of
by the char gers advanced c ontrol, but certai n uncommon errors in t he batter y can still arise.
Don’t leave the battery charger unattended for a long er period o f time.
• Only mount the charg er on a flat surface.
• This equipment may not be used by children or by thos e who can not read and understand
the manual if they are not supervi sed by a responsible per son who can guarantee that the
batter y charger is bein g used in a safe manner. Store an d use the battery char ger out of the
reach of children. Make sure that children do not play with th e batter y charger.
BATTERY TYPES AND SETTINGS
M100 can easily be conf igured to charge many diffe rent type s of 12V lead-acid batteries; wet
batter ies, MF, AGM and for most GEL-batteries .
The foll owing recommendations should, however, only be seen as guidelines. When in doubt,
always co nsult the bat tery manufac turer for further instructi ons.
Settin gs are made by pressi ng the “MO DE-button” an d stepping forward by pressing th e button
one step at a time, releas ing the but ton when the required mode is reached. After approx. 2
seconds, the charger activat es the chosen mode. The s elected mode is saved in t he charger’s
memor y and remains even whe n the charger is switched off.
MODE
”NORM AL” (14.4V)
Normal setting for wet batter ies, MF and for most Gel batteries.
Mode ”AGM” (14.7V)
This set ting is recommended f or batteries at te mperatur es below 5°C. It is also reco mmended
for many AGM batteries. This set ting is not recommended for mainte nance charging when t he
temperature at times exceeds +5°C. I n this case, the NORMAL mod e is recommended.
Mode ”SUPPLY” (13.6V)
In this mo de, the charger provides a constant voltage of 13. 6V. This is the best maintenance
mode for batterie s where max imum capac ity is import ant. It is not appropriate to charge a
completely discharged battery in Supply mode, since this will not result in a complete ly charged
batter y. The M100 can also be used as a power supp ly without a battery attached in this setting.
No counter voltage is required to start the charger in t his mode. Note that the ch arger is not
spark fr ee in this mode.
Mode ”R ECOND” (15.7V, 1.5A 0.5 –4h)
This mode is used to rec ondition very discharged batteries where you could expe ct a stratified
acid (high acid weight in the bott om, low on top). Use this mode wi th care because i t can cause
some water loss. 15.7V is normally n ot a problem f or electr onics, but consult th e manufact urer
when in doubt. Life of light bulbs can be reduced by higher voltages. Try to avo id using 12V
lamps co nnected to t he battery during this phase. Maximum effect and minimum risk for
electr onics is achieved by disconne cting the battery before charging.
CHARGING
Chargi ng batteries mo unted in a ve hicle:
1. The power c ord should be disconn ected befo re connecting or disconne cting the battery
leads.
2. Identify the pole that is grounded (attached to the chassis). Grou nd is normally connec ted to
the negative terminal.
3. Chargi ng a negatively grounded batter y. Connec t the red cable to th e positive p ole of the
batter y and the black cable to the vehicle’s chassis. Be caref ul not to connect the black cable in
the vici nity of a fue l pipe or the battery.
4. Charging a positively grounded batter y. Connec t the black cable to the negati ve pole of the
batter y and the red cable to the vehicle's chassis. Be caref ul not to conn ect the red cable i n the
vicinity of a fuel pipe or the battery.
Chargi ng of a battery not connected to a vehi cle:
1. The power c ord should be disconn ected befo re connecting or disconne cting the battery
leads.
2. Connect the red cable to the positive pol e of the batte ry and the b lack cabl e to the negat ive
pole.
Connecting th e provided cab les with eyelet terminals:
Make sure that the cable is not pinch ed or in contact with warm sur faces or sharp edges. When
the cable is mounted o n the battery, it should not be connec ted to the charger. Co nnect the
eyelet ter minals to the battery's po les - the red c able to the positive pole and the black cable to
the negative pole. Af ter this, the quick connector can be co nnected.
Reverse Polarit y Protectio n
If the bat tery cab les are connected incorr ectly, the reve rse polar ity protection will make sur e
that neit her the charger nor the battery are dama ged. In this c ase, the red warni ng lamp (0) will
be lit.
Star t charging
1. Connect the power co rd to the power outlet.
2. Set the proper char ging mode for the batte ry by pushing the Mode button until the correct
settin g is lit. Choo sing settings fo r your battery is describe d under ”BATTERY T YPES AND
SETTINGS”.
3. The lamp for Deep Discharged b attery (1) will i ndicate if t he battery volt age is low. If lamp
1 blinks, this indicates that the battery is lightly sul phated. Read more under ” CHARGI NG
PHASES ”
4. Norma l charging i s indicate d by the following lamps: D eep Disch arged (1), Bulk Charge (2),
Absor ption Charge (3) or Mainten ance Charging (4). When the maintenanc e lamp is lit, t he battery is f ully charged. The charge will restart if th e voltage dr ops. The charger can be connecte d
for months.
SUPPLY or RECOND are indic ated when the lamp s for these settings ar e lit (5 or 6).
5. If the bat tery cables are connected incor rectly, the reverse pola rity protection wi ll make sure
that neit her the charger nor the battery are dama ged. In this case, the red warni ng lamp (0) will
be lit.
6. If nothing happens . If the sett ing lamp is lit but no other li ght comes on, the connection to
the battery or to the chassis may b e poor, or the batter y may be faulty. Star t by improving the
contac t between the bat tery and the charger.
7. Charging can be interrupted at any time by disconnecting the power cord from the wall
socket or by p utting th e charger in " Standby" mode ( lamp A). Alway s disconnect the power cord
from the s ocket before removing the bat tery cab les. When yo u interrupt char ging of a battery
mounted in a vehicle, al ways disconnect t he battery cab le from the chass is before removing the
other bat tery cable.
CHARGING PHASES
Mode chosen: ”NORMAL” or ”AGM”
M100 is a multi stage fully automatic charger. Lamp B for chosen s etting ”NOR MAL” and lamp C
for chos en setting ”AGM”.
Desulphation (Lamp 1, bli nking)
Desulphation with pulsing for sulphated batteries. Indicated by blinking lamp 1.
Star t (Lamp 1)
Starting phase for charging. The star ting phase conti nues until the batter y’s terminal volt age
has risen over a preset level. At this po int, charging goes into the bulk phas e. If the terminal
voltage has not reached the pres et level within 8 hours, ch arging is suspended. The error mo de
is indicated. This in dicates a battery wh ich is fault y or has too large ca pacity. If a large battery
is charged that has been severely di scharged, it may be n ecessar y to restart th e charger af ter 8
hours. Start is indicated by lamp 1.
Bulk (La mp 2)
Primar y charging wher e approximately 80% of the charging happens. The charger d elivers
maximu m voltage until the terminal volta ge has risen to the pr eset level. After a number of
hours, the charger g oes on to the next pha se, even if maximum voltage is not reached. Bulk is
indicated by lamp 2.
Absor ption (Lamp 3)
Final cha rging, voltage is kept at the preset leve l. During this phase, the voltage is gradually
reduce d. If the maximum le ngth of time f or Absorption is exceeded, t he charger automatically
continues with Analysis. Absorption is indicated by lamp 3.
Analysis (Lamp 3)
Chargin g is suspended for a shor t period and the battery vo ltage measured. If it fa lls too
quickly, the batter y is probabl y faulty. Char ging is suspended and an error i s indicate d (lamp 0).
Maint enance c harging - float (Lamp 4)
During t he first 10 days of maintenance ch arging the b attery is maint ained with const ant voltage, 13.6V. Float -maintenance is indi cated by lamp 4.
Maint enance c harging - pulse (La mp 4)
The state of charge var ies between 95% and 100%. The b attery r eceives a pu lse when the
voltage sinks, keepi ng the battery in good shape when it is not being used. The charger can be
connec ted for months at a time.
If the bat tery is charged and/or the batte ry’s term inal voltage drops, the char ger starts a charge
pulse until the volta ge has reach ed the preset level, 14.4V or 14.7V. The c harge pulse is then
interr upted and the cycle is repeated as long a s the charger is in pulse maintenance phase. If
the term inal voltage drops even lower, the charg er automatically reverts to the beginning of t he
charging curve. Pu lse maintenance phase i s indicate d by lamp 4. If pos sible, check the water
level in the battery.
Chosen mode: ”SUPPLY”
M100 has a Supply mode set ting which has a co nstant volt age of 13.6V and curr ent up to 7A.
This mode can also be used for maintenance charging of an already fully charged battery,
called Float maintenance. This type of cha rging keeps t he battery at 100 % charge. Th e constant sma ll overchar ge can also increase water loss. A bat tery does not have to be connec ted
for the ch arger to del iver voltage. This mean s that the spark protect ion is not active in this
mode. It is n ot appropriate to charge a completely di scharged battery in Supply mode, since
this will not result in a c ompletely char ged battery. In this mode, M100 can also be used as a
power gen eration un it for operating equipment that requires 13.6V an d a maximum of 7A. If the
selected current exceeds 7A, the o utput volt age will dro p as the load increases. The charger
has electronic over load protection in this mode, which is activated if th e charge is so great that
the output voltage f rom the charger falls b elow around 9V and the cur rent ís around 7A. In the
event of an over load, the charge r goes into error mode (lamp 0). Supply mode is indicated w ith
lamp D and la mp 5.
Chosen mode: ”RECOND”
M100 has a Rec ond mode which is used to r econdition a battery that has been severely
discharged. The bat tery is first c harged using the m ode ”NORMAL”. When the analysis phase is
complete, the charger begins reconditioning the battery by providing a c onstant current of 1.5A
and a maxi mum voltag e of 15.7V. After 0. 5–4 hours, the battery is comp letely reconditioned
and the charger goes into pulse maintenance. The batter y is ready to be used, o r store it wit h
pulse mai ntenance active until you are ready to u se the battery. Recond is indicated by lamp
E and lamp 6. N ote that the recon d phase begins with nor mal charging and that th e charger
therefore will indicate the ch arging phases accor ding to the de scripti ons above first. Lamp 6 is
first lit when the reconditioning begins.
TEMPERATURE PROTECTION
M100 is protected from being overheated. The power will be re duced if the ambient temperature
is raised.
MAINTENANCE
The char ger is mainte nance fre e. Note that disassembly of the charger is not per mitted and
will void the warranty. If the power c ord is damaged, th e charger must be left to t he reseller for
maintenance. The case can be cleaned with a s oft damp cl oth and mild cleanser. The charg er
should be disconne cted from t he power supply whi le cleaning.
