Crown Industrial Deep Cycle Batteries
Crown Industrial deep cycle fork lift type batteries
A note on warranties and ratings for Crown industrial batteries:
Crown batteries have solid Lead plates composed of 5-6% Antimony for strength - (Rolls-Surrette is 4-5%). These batteries are designed for extremely heavy usage in fork lifts, electric mining and railroad equipment, and other large motive power applications. They are rated at 1800 to 2000 complete cycles down to 80% discharge. At the usual 30-60% discharge that most PV systems operate at, you can expect 3,000 to 8,000 cycles (up to 20 years). They are extremely vibration and shock resistant.
These are the type of batteries that we use in many of our large systems (see photos for a couple of our CP installations in the USA. These are large pictures, so may take a minute to load).
We recommend that Hydrocaps be ordered with the batteries - using Hydrocaps will reduce water consumption by 80-95% and reduce maintenance.
These batteries are very heavy, and it is recommended that you insure that you have the manpower or power equipment to handle them before we ship them. One advantage of being so heavy is that theft is extremely difficult - all except the smallest batteries will weigh in excess of 500 pounds, and some as much as 4,000.
Crown has been manufacturing industrial batteries since 1926. Crown manufactures a wide range of batteries, including batteries for forklifts, golf carts, and electric mine engines. Of those suitable for use in solar electric power systems, there are over 1500 sizes and configurations possible. We have listed only a few of the most popular sizes, along with a few examples of other sizes available. These are LARGE batteries, and are furnished as complete units of 3, 6, or 12 cells enclosed and sealed in a heavy duty steel casing.
The table below show specifications for the most common Crown Industrial batteries. The specifications for both are identical for all practical purposes. These are assembled units in steel trays. Prices shown are for standard 12 volt configurations. 6, 8, 12, 18, 24, 32, 36, and 48 volt are available at approximately the same price per cell. Prices shown are per 12 VOLT PACK - other voltage configurations will be the same price per 12-volt pack. All are rated at 1500 cycles to 80% discharge, and 5,000 cycles to 20% discharge, minimum.
