Deltran Battery Tender Manual

Deltran Battery Tender
12V 5Amp and 24V 2.5Amp Selectable Charger
For 12V Four Cell Lithium (LiFePO4) Batteries, 24V Eight Cell Lithium (LiFePO4) Batteries,
12V Six cell and 24V Twelve Cell Lead-Acid/AGM Batteries
IMPORTANT SAFETY INSTRUCTIONS
1) SAVE THESE INSTRUCTIONS – This manual contains important safety and operating
instructions for battery charger model P/N 022-0258
2) Do not expose charger to rain or snow.
3) Use of an attachment not recommended or sold by the battery charger manufacturer may
result in a risk of fire, electric shock, or injury to persons.
4) To reduce risk of damage to electric plug and cord, pull by plug rather than cord when
disconnecting charger.
5) An extension cord should not be used unless absolutely necessary. Use of improper
extension cord could result in a risk of fire and electric shock. If an extension cord must
be used, make sure:
a) That pins on plug of extension cord are the same number, size, and shape as those of
plug on charger;
b) That extension cord is properly wired and in good electrical condition; and
c) That wire size is large enough for ac ampere rating of charger as specified in Table 1
TABLE 1
Length of Cord, Feet
AWG Size of Cord
6) Do not operate charger with damaged cord or plug – replace the cord or plug
immediately.
7) Do not operate charger if it has received a sharp blow, been dropped, or otherwise
damaged in any way; take it to a qualified serviceman.
8) Do not disassemble charger; take it to a qualified serviceman when service or repair is
required. Incorrect reassembly may result in a risk of electric shock or fire.
9) To reduce risk of electric shock, unplug charger from outlet before attempting any
maintenance or cleaning. Turning off controls will not reduce this risk.
10) WARNING – RISK OF EXPLOSIVE GASES.
a) WORKING IN VICINITY OF A BATTERY IS DANGEROUS. BATTERIES
GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION.
FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT YOU FOLLOW THE
INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
b) To reduce risk of battery explosion, follow these instructions and those published by
battery manufacturer and manufacturer of any equipment you intend to use in
vicinity of battery. Review cautionary marking on these products and on engine.

11) PERSONAL PRECAUTIONS
a) Consider having someone close enough by to come to your aid when you work near
a battery.
b) Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes.
c) Wear complete eye protection and clothing protection. Avoid touching eyes while
working near battery.
d) If battery acid contacts skin or clothing, wash immediately with soap and water. If
acid enters eye, immediately flood eye with running cold water for at least 10
minutes and get medical attention immediately.
e) NEVER smoke or allow a spark or flame in vicinity of battery or engine.
f) Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark
or short-circuit battery or other electrical part that may cause explosion.
g) Remove personal metal items such as rings, bracelets, necklaces, and watches
when working with a battery. A battery can produce a short-circuit current high
enough to weld a ring or the like to metal, causing a severe burn.
h) Use charger for charging Lead-Acid/AGM/Lithium (LiFePO4) batteries only. It is
not intended to supply power to a low voltage electrical system. Do not use battery
charger for charging non-rechargeable batteries that are commonly used with home
appliances. These batteries may burst and cause injury to persons and damage to
property.
i) NEVER charge a frozen battery.
12) PREPARING TO CHARGE
a) If necessary, to remove battery from vehicle to charge, always remove grounded
terminal from battery first. Make sure all accessories in the vehicle are off, so as not
to cause an arc.
b) Be sure area around battery is well ventilated while battery is being charged.
c) Clean battery terminals. Be careful to keep corrosion from coming in contact with
eyes.
d) Add distilled water in each cell until battery acid reaches level specified by battery
manufacturer. Do not overfill. For a battery without removable cell caps, such as
valve regulated lead acid batteries, carefully follow manufacturer's recharging
instructions.
e) Study all battery manufacturers specific precautions such as removing or not
removing cell caps while charging and recommended rates of charge.
f) Determine voltage of battery by referring to car owner's manual and make sure that
output voltage selector switch is set at correct voltage. Do not use the battery
charger unless battery voltage matches the output voltage rating of the charger.
13) CHARGER LOCATION
a) Locate charger as far away from battery as dc cables permit.
b) Never place charger directly above battery being charged; gases from battery will
corrode and damage charger.
c) Never allow battery acid to drip on charger when reading electrolyte specific gravity
or filling battery.
d) Do not operate charger in a closed-in area or restrict ventilation in any way.
e) Do not set a battery on top of charger.
14) DC CONNECTION PRECAUTIONS
a) Connect and disconnect dc output clips only after setting any charger switches to
offposition and removing ac cord from electric outlet. Never allow clips to touch
each other.
b) Attach clips to battery and chassis as indicated in 15(e), 15(f), and 16(b) through
16(d).
