Operation & Charging
•The Oasis battery can be operated in a partial state of charge for long periods of time
without sustaining any permanent damage.
•The Oasis may emit gas during the first 10-20 charge cycles. This is normal.
•The maximum recommended discharge current is 0.7C for extended periods of time to
ensure the longevity if the battery. The FF battery can discharge faster than that for short
periods.
•If you have hardware that requires a Peukerts constant to be entered, we recommend
that you do not change the factory settings due to the large inaccuracies based on varying
discharge rates. The Peukerts constant for the FF battery for the 10hr and 20hr rate is
1.07. It is 1.12 for 6.5hr and 1.8hr rate. Keep in mind that whatever Peukerts correction
you use, you will lose accuracy with extremely slow discharges.
•If you have hardware that allows the user to enter a temperature coefficient , use
24mV/C° for temperature compensation.
•For a complete charge cycle, charge the Oasis to 14.4V with temperature compensation
(bulk phase) and continue charging until the charging current drops to 1.5A (absorption
phase, time will vary). You DO NOT need to fully charge the Oasis each cycle in order to
maintain the capacity and only need to perform a complete charge cycle when you want
to maximize the capacity for the following discharge cycle.
•For charging sources that may be charging the battery for an extended period of time
(solar, or an alternator if motoring for a while); set the float voltage to 13.4V. The Oasis
does not require a float charge. But, if float charging, due to the Oasis’s longer projected
lifespan, it is important to keep the float voltage at 13.4V to ensure the battery lasts for as
many cycles as possible. Reset to bulk phase: for programmable charging sources, adjust
the “reset to bulk phase” to occur if the battery voltage drops below 12.0V for >1 minute.
•The optimum operating temperature for a lead-acid battery is 25°C (77°F). As a rule of
thumb, every 8-10°C (14-18°F) rise in temperature will cut the battery life in half. Note
that continuous duty at elevated temperature will shorten the life of any battery.
Restoration Charge
As stated, the Oasis can operate in a partial state of charge for long periods of time without
sustaining any permanent damage. The usable capacity will decrease, however, with each cycle
within a partial state of charge, up to a point. In order to regain the full original capacity and in
some cases more, it is necessary to perform a restoration charge. To perform the restoration
charge: charge the Oasis to 14.4V and continue to charge until the current drops to 0.6 A. Fully
discharge the battery to 10.5V, and then repeat the same charge cycle. At this point, the Oasis
should have regained full capacity.
