BUYERS BEWARE: There are solar/battery web sites selling Batteries with Apparent High Amp Hour capacities advertised at the 100 hour rate (i.e. C/100) We don't believe the 100 hour rate is a practical listing for battery buyers. It just a way to make a battery look larger and better than it actually is (higher Amp Hour number)

All of our battery Amp Hour ratings are honestly listed at the solar industry standard 20 hour rate (a lower Amp Hour number) Our low pricing is always the best... if somebody else's pricing looks to be better BEWARE of the 'ole amp hour rate switcheroo. We have been in the battery business since 1969 - Thirty-eight years. We haven't been in business this long by fooling our customers.

CAUTION: to salt water sailors... Chlorine gas, deadly in small doses, is the result of mixing sulphuric acid with saltwater. For this reason we don't recommend ever venturing out in salt water with Wet Cell batteries.

The Solar Star Batteries are Dual Terminal, AGM sealed batteries. They require no maintenance, there is no corrosive spray causing the usual mess in the battery box and at the connecting cables. They are quite resistant to freezing and they have a very low self discharge rate, enabling them to sit unattended, for much longer than their wet cell counterparts.

Another great feature... for the marine market, when your boat is healed over hard, AGM batteries are unaffected by the position of the battery, unlike wet cells, in which part of the plates can rise up out of the electrolyte and hard sulfate (die) decreasing their capacity, and your investment.

Most battery dealers and the general public at large believe that an advantage of sealed AGM and Gel  batteries is the absence of explosive gasses being vented during charge. We believe this is a dangerous assumption, here's why;

Contrary to popular opinion both AGM and Gel Cell batteries can indeed out-gas hydrogen... Proper charging usually doesn't pop the vent caps open, and normally  hydrogen and oxygen are recombined in the cells. BUT... During overcharge conditions, the internal pressure of the gasses in the cell could exceed the 2 PSI limit allowing the vent seals to out-gas hydrogen... Overcharging (Equalization) which force the vented caps open can be damaging to the batteries if maintained long enough, but slight overcharges are not damaging.

So don't let 'em tell you otherwise...gel and AGM batteries do emit explosive gases! Remember you must provide sufficient ventilation to avoid concentration of hydrogen and oxygen, just as with flooded cells. To do otherwise could be risky.

Our Solar Star batteries, manufactured specifically for SOLAR and other renewable energy applications, are designed to offer up to 12 years of life!  One Year free replacement Warranty.

The Solar Star Line of batteries have been made for and designed by The Solar Biz to meet the needs of our customers for good quality, high amp hour, 2 volt cells. Our Solar Star 2 Volt cells enable you to have a single, high quality, series connected string, of enough amp hours to provide decent autonomy.

In the past in order to achieve a higher amp hour bank of batteries, most folks resorted to multiple parallel connected strings of smaller batteries. This design was an expensive compromise that resulted in a drastically reduced life of the battery bank.

 

Parallel connected strings of the kind of batteries most folks buy are never impedance matched. This scenario makes equal charging quite difficult, resulting in bad cells in the string with the most resistance in a short amount of time, around 3.5 to 4.5 years. I think batteries are too expensive and too heavy, to have to replace in this short time period.

There is not enough space here to answer all of the questions that the foregoing raises, so call Tom at 888-826-0939 and he will be happy to discuss this with you. Tom has 40 years experience with batteries in all sorts of situations, everything from Over the Road Trucks to remote off grid systems, heavy equipment, boats, RV's, aircraft, telecom, on grid back-up, computer network back up, commercial power back-up... the list goes on. If you have any questions about batteries Tom has probably designed and installed it... and, he talks alot!

Does *FREE FREIGHT mean the batteries will be delivered to my door?

Not necessarily. Free freight means the batteries will be shipped from the factory anywhere in the lower 48 states, to the nearest business with a forklift or loading dock (building supply, hardware store, rental equipment company, etc.), or compatible truck terminal. Truck terminals will usually help you to load your truck.

California Proposition 65 Warning
Battery posts, terminal, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
