Rolls S6 L16-HC (S-550) lead-acid batteries are considered “new” as long as they are less than 1 year old. Generally this is no issue, even at 1 year of sitting on the shelf they should work fine. All new lead-acid batteries need a handful of cycles to reach full capacity, and those sitting on the shelf for some time are no different. Specific gravity (SG) values of the cells may be quite low when you receive them, and when put in service new batteries should receive an initial full charge, sometimes even an equalize charge. Depending on your charge source(s) it can take many hours before all the cells reach “full” or a SG of 1.265. It is important to take the time and do this!
Rolls Surrette has built a solid reputation over the years as one of the best, if not THE best, sources of deep-cycle batteries for renewable energy systems. Their batteries feature a high cycle life with thick positive battery plates and a large liquid reserve. Surrette batteries are known for their unsurpassed reliability.
The 4000-series batteries are designed specifically for renewable energy applications and come with a solid 3 year full replacement warranty. With good battery care many get 10 to 12 years of service out of these batteries. Our battery care instructions can help get the most out of your batteries.
Adding batteries in series increases the Voltage, while keeping the Amp-hour size the same. Adding batteries in parallel keeps the Voltage the same, while increasing the Amp-hour size of the battery bank. For example, two S6 L16-HC batteries in series makes for a 12 Volt / 445 Ah battery bank. Adding another string of two S6 L16-HC batteries in parallel to these will increase the bank size to 12 Volt / 890 Ah.
Recommended Charge Settings (at 25C)
| Charge State | 12 Volt | 24 Volt | 48 Volt |
|---|---|---|---|
| Bulk | 15.0 Volt | 30.0Â Volt | 60.0Â Volt |
| Absorb | 15.0 Volt | 30.0 Volt | 60.0 Volt |
| Float | 13.5 Volt | 27.0 Volt | 54.0 Volt |
| Equalize | 15.8 Volt | 31.6 Volt | 63.2 Volt |
| Temperature Compensation: -5 mV/°C/cell |
Equalize time: 2.5 hours, add distilled water as-needed halfway through
Absorb time:Â 0.42 x C / I, where C is the 20-hour battery bank capacity and I is the real-world charge current
For example, a 12 Volt bank of two S6 L16-HC batteries, 445Ah battery bank, with 1000 Watt in solar PV would have a realistic charge current of around 65 Amp in full sun. That makes for an absorb time of 0.42 x 445 / 65 = 2.88 hours = 2 hours 50 minutes
Maximum charge current: 15% of 20-hour battery bank capacity (ie. 0.15 x 445 = 66A for an S6 L16-HC battery for example), never more than 20%
Low-Voltage cut-off: 11.1 / 22.2 / 44.3 Volt (corresponds to about 80% Depth-Of-Discharge)
