LIFELINE BATTERY OWNER’S MANUAL
LIFELINE BATTERY OWNER’S MANUAL
Congratulations on the purchase of a new Lifeline battery! Lifeline has been the leading name in AGM (Absorbed Glass Mat) batteries since 1993. The quality and durability of the Lifeline battery series has been proven again and again in military and commercial applications worldwide.
The AGM difference:
20% faster recharge than a conventional vented battery and gel cells.
100% maintenance free. No addition of water needed.
Classified as “NONSPILLABLE”
Tested to stringent military shock and vibration standards.
Designed to reduce outgas under normal charging conditions.
Sizing a battery bank:
It is always good to have twice the battery capacity that an application requires. This will promote long battery life and also reduce the amount of recharge time.
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 charging voltages are recommended for maximum battery life
for all Lifeline models.
|
| Charging Phase | 2 Volt Battery | 6 Volt Battery | 12 Volt Battery
| | Bulk/Absorb | 2.40 - 2.46(2.43 midpt) | 7.20 - 7.38(7.29 midpt) | 14.4 - 14.8(14.6 midpt) |
| Float | 2.23 - 2.27(2.25 midpt) | 6.69 - 6.81(6.75 midpt) | 13.4 - 13.6(13.5 midpt) |
NOTES:
1. Use midpoint values for most applications. Lower voltages may be suitable for light-duty applications and higher voltages may be suitable for heavy duty applications.
2. For 24 Volt Systems, multiply 12 Volt setting by 2.
3. Charge voltage should be adjusted if battery temperature varies by more than 10°F from 77°F. Consult website for further guidance (www.lifelinebatteries.com).
Conditioning/Equalizing Charge: 15.6 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 as fully charged as possible, start the conditioning/equalizing charge.
For maximum battery life, a battery must be recharged to 100% capacity. Recharging to less than 100% may result in premature battery failure. Lifeline batteries are not covered under warranty if they are not recharged properly. For more information, please refer to our warranty policy.
For Inverter/Charger applications:
Refer to the Inverter/Charger manual to ensure the correct voltages have been set.
Knowing when to recharge:
For maximum battery life in cycling applications, do not discharge the battery bank below 50%. Discharging the bank repeatedly to 100% will shorten the battery life. The open circuit voltages listed below correspond to the various states of charge:
| State of Charge | 2 Volt Battery | 6 VoltBattery | 12 VoltBattery |
| 100% | 2.16V or more | 6.50V or more | 12.8V or more |
| 75% | 2.10V | 6.30V | 12.6V |
| 50% | 2.03V | 6.10V | 12.2V |
| 25% | 1.97V | 5.90V | 11.8V |
| 0% | 1.90V or less | 5.70V or less | 11.4V or less |
Multiple Batteries:
If there is more than one battery in the battery bank, the following guidelines should be used:
Always use batteries of identical make, model and with the same manufacturing date.
Make sure the battery cable is not undersized for the battery system.
Make sure the battery cables are connected to the terminals correctly. If unsure, professional assistance is recommended.
Storage:
The following recommendations may be helpful if the battery is to be stored:
When storing the battery, it is not necessary to leave it on charge. Disconnect the negative battery cable. This will prevent inadvertent discharging of the battery that may lead to a complete discharge.
Fully charge the battery before putting it in storage and store in a cool place.
Boost charge the battery every 3 months to ensure maximum battery life.
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 does not cover consequential damage or injury, discharged batteries, rental, freight or installation costs. Replacement batteries will be provided at the time the warranty is requested. Credit will not be issued after the purchase of a new battery. For warranty questions, please contact Lifeline Inc at (800) 527-3224.
