Service History of the Battery:
Obtaining the service history of the battery and any history of problems from the owner may help in determining the cause of failure.
Visual Inspection
Visual inspection of the battery may reveal signs of abuse which may have caused failure.
The battery's age can be an important factor in determining the cause of failure. The length of time in service determines whether the battery failed prematurely or had simply worn out. All battery manufacturers date their poduct by stamping a date code into the cover or container. This code can be used to dermin the actual age of the battery. The individual manufacturers should be consulted regarding their specific date codes.
More important is the date the battery was sold. This date determines the time the battery has been in service. The date of purchase on all battery bought at Battery Sales is indicated on a dater label with a letter and number combination, e.g. A1 would indicate January 2011.
Overcharging and Undercharging Batteries
The vehicle's charging system can have a profound effect upon the life of a battery. A high voltage regulator setting can cause excessive gassing and water loss, thermal runaway, and eventual damage to plates and separators. We often see these on vintage sports cars. This is extremely common when replacing a lead-acid battery with a sealed gel battery. Gel batteries are constantly being overcharged and failing because of the voltage regulator. If the voltage regulator setting is too low, there is a high resistance in the charging circuit, or the charging system is not capable of handling the accessory load the battery will be in a constant state of discharge. If this happens over a long period of time, the sulfate which deposits on the plates can become hard and crystallize. In this form, the plates may not accept a charge under normal conditions and may even cause short circuits through the separators due to a build-up of lead sulfate through the pores which is converted to lead shorts during recharge.
Voltage regulator settings vary among vehicle manufactures and may not be adjustable. They should be checked with the indivdual manufacturer before adjustment is atempted. Different battery types using different grid alloys and manufacturing processes may require different charging methods; this includes Lead Acid Batteries, AGM Batteries, and GEL Batteries.
Sizing a Lifeline Battery Bank:
It is always good to have twice the battery capacity that an applicaiton requires. This will promote long battery life and also reduce the amount of recharge time.
Lifeline Battery Charging:
Warning: All batteries must be adequately vented during charging to avoid accumulation of explosive hydrogen gasses. never install or charge in a sealed container or room.
The following chargin voltages are recommended for maximim battery life for all Lifeline Battery Models:
Volts Per Cell 6 Volt Battery 12 Volt Battery
Bulk/Absorb 2.37 - 2.40 7.10 - 7.20 14.2 - 14.4
Float 2.20 - 2.23 6.60 - 6.70 13.2 - 13.4
Conditioning / Equalizing Charge for Lifeline Batteries:
Charge at 15.5 volts for 8 hours.
Conditioning/equalizing should only be done when the battery is showing symptoms of capacity loss. If conditioning/equalizing is necessary, first go through the normal charge cycle. Once the battery is fully charged, start the conditioning/equalizing charge.
Note: For maximum life, batteries must be periodically recharged to 100% capacity. Continually recharging to less than 100% may result in premature capacity loss. It is recommended that batteries be recharged to 100% at least every 5-10 cycles.
For Inverter/Charger Lifeline Battery Applications:
Refer to the inverter/charger manual to ensure the correct voltages have been set.
Knowing when to recharge your Lifeline Battery:
As a general rule, batteries should be recharged immediately after use or when they reach approximately 50% depth of discharge. Discharging to 60% or even 100% occasionally will not harm the batteries, but if this is done frequently it will shortent he battery's overall life. If batteries are discharged beyond 50%, it is important to recharge as soon as possible (same day if possible). The depth of discharge can be estimated by measuring the "open circuit voltage" as shown in the following table. Note that the battery must be at rest with no loads for at least 4 hours to obtain an accurate "open circuit voltage"
Depth of Discharge Volts/cell 6 Volt Battery 12 Volt Battery
0% 2.3V or more 6.4V or more 12.8V or more
25% 2.08V 6.25V 12.5V
50% 2.03V 6.10V 12.2V
75% 1.98V 5.95V 11.9V
100% 1.93V or less 5.80V or less 11.6V or less
Multiple Lifeline Batteries:
If there is more than one battery in the battery bank, the following guidelines should be used:
Storing Lifeline Batteries:
Follow these guidelines if the battery is to be stored for an extended period of time (more than a month):
Lifeline Battery Warranty:
Lifeline batteries have a 5-year pro-rated warranty with a 1-year free replacement (12-month prorated warranty in applications other than marine or RV). The warranty period starts at the time of purchase. If the original receipt is lost, the warranty will be based on the battery date code. The warranty covers defects in material, workmanship and failure, except where such failure is due to abuse, neglect or breakage. The warranty period starts at the time of purchase. If the original receipt is lost, the warranty will be basedon the battery date code. The warranty covers defects in material, wrokmanship and failure, except where such failure is due to abuse, neglect or damage to injury, discharged batteries, rental freight, or installation costs. Replacement batteries will be provided at the time the warranty is reuested. Credit will not be issued after the purchase of a new battery.

FOR YOU BATTERY NEEDS!
INTERNATIONAL EXPORTS WELCOMED!
To reduce the chances of a battery exploding:
Ever felt confused when purchasing a new battery and the dealer is throwing out words like Flooded battery, AGM, Hydrometer, and CCA? Jargon specific to batteries that a lot of people are just not familiar with....
Well let us simplify those terms for you so you can blend in with the pro's or rather not feel so confused and bamboozled.
Glossary:
AGM- also know as Absorbed (absorptive) Glass Mat. Technique for seal lead-acid batteries. Electrolyte is absorbed in a matrix of glass fiber, which holds the electrolyte next to the plate and immobilize it, preventing spills. AGM batteries tend to have good power, low internal resistance, good behavior during charging.
Amp, Ampere- unit of electrical current
Amp Hour- unit of electrical energy, one amp of current flowing for one hour. (AH)
Cell- A single battery canister usually grouped together with other cells to form battery packs of different voltages and amperage.
CCA- refers to the number of amperes a battery can support for 30 seconds at a temperature of 0°F until the battery voltage drops to 1.20 volts per cell, or 7.20 volts for a 12V battery. Thus, a 12V battery that carries a rating of 600 CCA tells us that the battery will provide 600 amperes for 30 seconds at 0°F before the voltage falls to 7.20V
Electrolyte- conductive medium in which current flow is due to the movement of ions. In a lead acid battery, the electrolyte is a solution of sulfuric acid.
Flooded cell- the electrolyte is an ordinary liquid solution of acid. Flooded cells are probe to making gas while being charged. They must be periodically checked for fluid level and water added as necessary. Flooded cells are also typically less expensive than agm or gel type.
Gel battery- contain acid that has been "gelled" by the addition of Silica Gel, turning the acid into a solid mass that looks like gelatin. The advantage of these batteries is that it is impossible to spill acid even if they are broken.
Hydrometer- tool for testing the specif gravity of a fluid, such as the electrolyte in a flooded battery.
RC-The reserve capacity of a battery is defined as the number of minutes that it can support a 25 ampere load at 80°F until its terminal voltage drops to 1.75 volts per cell or 10.50 volts for a 12V battery. Thus a 12V battery that has a reserve capacity rating of 100 signifies that it can be discharged at 25 amps for 100 minutes at 80°F before its voltage drops to 10.75 volts.
Sulfation- even though lead sulfate is created in material of plates during normal discharging, this term is used to describe the generation of a different from (large crystals) of lead sulfate which will not readily convert back to normal material when battery is charged. Sulfation occurs when a battery is stored to long in a discharged condition. If it is never fully charged, or if electrolyte has become abnormally low due to excessive water loss from overcharging and or evaporation.
Volt- the unit of measurement of electrical potential or pressure. Most batteries com in 6, 12, 24.
Watt-the unit for measuring electrical power, i.e., the rate of doing work, in moving electrons by, or against, an electrical potential. Formula: Watts = Amperes x Volts.
Warning signs to look for:
