ACCU 12V 18Ah
Please read the following manual carefully before the first use and keep it for future reference.
Scuba diving is treated as an extreme sport and requires proper training and certification. Using scuba
equipment, ACCU 12V 18Ah included, by an untrained and inexperienced person without proper certification
may cause health damage and even risk of death.
The set includes:
- 1 x ACCU 12V 18Ah
- 1 x dedicated charger
- 1 x RCA port cap
Technical details:
- 12V
- 18Ah
- Li-Ion 12V battery pack
- max power consumption from both ports: 200W
Tech specification
ACCU 12V 18Ah is dedicated for underwater heating systems with max voltage 12V using compatible connection system
through E/O cord and for compatible underwater light heads equipped with light-for-me RCA or E/O (through additional
light-for-me RCA-E/O cord) connection. Make sure the used heating system and/or underwater light head are compatible
before connecting them to ACCU 12V 18Ah. The manufacturer does not take any liability for any damage caused by
connecting ACCU 12V 18Ah to incompatible heating system and/or underwater light head.
Purpose of use
!
!
ACCU 12V 18Ah is equipped with two RCA ports marked as DIRECT (direct connection to the battery pack) and SWITCH
(connected to the battery pack through a switch).
Charging is done through the DIRECT port only. Connecting charger
to the SWITCH port can cause battery pack damage.
Prior to starting the charging process make sure that ACCU 12V 18Ah is dry. Then disconnect the device connected to the
DIRECT RCA port or unscrew the cap and dry this port as well with a clean tissue.
Make sure the ACCU’s switch is in OFF position - it must stay OFF throughout the whole charging process. Use only the
charger provided with the set. Before plugging the charger in, check its condition thoroughly; in case of noticing any
mechanical damage to the charger, cut or broken cable or any other fault which may influence its proper work, do not use
the charger.
In order to start the charging process plug the charger’s RCA connector into the DIRECT port, then plug the charger to the
mains. The charger will go through a self-test (power red diode on, all 4 green diodes flash one by one) and then will start
the charging process, which is indicated by green diodes flashing. Each solid green diode indicates 25% charge of the
battery pack. The charging process is finished when all the four green diodes are on. Unplug the charger from the mains
Charging
1/4

ACCU 12V 18Ah is equipped with two RCA ports:
• DIRECT - used for charging, connecting light-for-me light heads with RCA connection and additional RCA-E/O cord (to connect
compatible light head with E/O cord)
• SWITCH - used for connecting RCA-E/O cord and heating system. Switch placed in ON position does not draw any current
when there is nothing plugged into this port. Disconnecting the E/O cord underwater (regardless of which port it is connected
to) may cause irreversible damage to the E/O connector. Switch should be in OFF position when this port is not in use.
To switch on/off the RCA SWITCH port - move the red switch according to the ON / OFF marks. The switch should be in OFF
position when the SWITCH RCA port is not in use, between the dives and during the charging process.
Prior to connecting the heating system and/or light head to
an RCA port check the condition of orings sealing the RCA
port, if necessary grease them with pure vaseline (petroleum
jelly). Damaged, torn or cut orings require immediate
replacing.
Check also the cables / cords connected to RCA ports - both
from the heating system and underwater light heads - any
damages, tears or breaks require fixing / servicing - if
immersed in water they may cause flooding and irreversible
damage to the battery pack.
If only one RCA port is used, closed the other one with the
RCA cap provided. Open RCA port is not watertight and
when immersed in water will flood the ACCU and cause
irreversible damage to the battery pack.
Usage
After the dive rinse the equipment in lukewarm water, make sure the RCA ports are closed (with RCA cap or RCA-E/O cord or
underwater light head), then dry it and check its condition - any damages that may influence the proper work of the ACCU and
the devises connected to it must be fixed / serviced by an authorised service point before next dive.
The ACCU 12V 18Ah should be stored in a dry room with its battery pack charged. The ACCU should not be left for a longer time
with low charge level of its battery pack. In case of leaving the ACCU with its ports open, make sure they are not prone to
increased humidity or water entering inside the canister.
RCA-E/O cord should not be stored in a bend position, prone to any breaks or damages. Its E/O connection should be clean and
dry, if needed it can be slightly greased with pure vaseline (petroleum jelly).
RCA ports should be kept clean and slightly greased with vaseline (petroleum jelly). Sealing orings must be checked regularly
and kept clean and greased.
Storage
2/4
Switch placed on the bottom can be easily reached
and operated in different kit configurations and is
easy to switch on/off even in dry gloves with thick
inner insulatiotn.
Make sure the sealing orings placed in the
RCA ports are in good condition, if needed
grease them with petroleum jelly. Damaged
orings need replacing.

Burn times
3/4
Burn times of ACCU 12V 18Ah depends on the total power drawn by the connected devices. The maximum power that can be
drawn from both ports is 200W.
The below table shows max burn times of ACCU 12V 18Ah with Santi™ heating systems and underwater light heads
LIGHT-FOR-ME. Given burn times of ACCU 12V 18Ah may differ from real burn times of +/- 10%.

Troubleshooting
Problem Solution
RCA-E/O cord is broken / cut /
torn or damaged.
RCA-E/O cord needs servicing / replacing. Do not take the broken equipment
underwater. Contact the authorised service point / manufactorer of the
ACCU.
One of the RCA ports was left
open and the ACCU was taken
underwater.
Switch is on ON position, the
heating system / light head
does not work.
Charge the ACCU according to the manual. Make sure the heating system /
underwater light head are connected to the proper RCA port. Check the
condition of connected device - if necessary contact its manufacturer. If all is
checked and seems to be fine, and the connected device still does not work,
contact the manufacturer / authorised service point of the ACCU.
Charger seems to be broken /
does not charge properly / one
of its cord is broken.the rest.
Charger needs servicing / replacing. Do not take the broken equipment
underwater. Contact the authorised service point / manufacturer of the
ACCU.

a device connected to the ACCU
18Ah 12V
Follow the manual provided with the device by its manufacturer. If in doubt,
contact its authorised service point or manufacturer.
