Some background on batteries

• All Lead-Acid batteries supply about 2.14 volts
  per cell (12.6 to 12.8 for a 12 volt battery)
  when fully charged. Batteries that are stored for
  long periods will eventually lose all their
  charge. This "leakage" or self discharge varies
  considerably with battery type, age,
  temperature. It can range from about 1 to 15
  per month. Generally, new AGM batteries have the
  lowest, and old industrial (Lead-Antimony plates)
  are the highest. In systems that are continually
  connected to some type charging source, whether
  it is solar, wind, or an AC powered charger this
  is seldom a problem. However, one of the biggest
  killers of batteries is sitting stored in a
  partly discharged state for a few months. A
  "float" charge should be maintained on the
  batteries even if they are not used (or,
  especially if they are not used). Even most "dry
  charged" batteries (those sold without
  electrolyte so they can be shipped more easily,
  with acid added later) will deteriorate over
  time. Max storage life on those is about 2-3
  years.

Surrette

• Rolls Dual Container Construction
• More Power - Less Weight
• Environmentally Friendly No Acid Leakage
• Each cell is assembled in its own inner container
  made of high temperature, durable polypropylene
  with the inner cover heat bonded to the
  container, thus acid leakage is eliminated. The
  cells are then assembled into a high density
  tough polyethylene outer container with a
  removable lid. Even if the outer container were
  to break the battery would still be operable
  without the harmful affects of sulfuric acid
  spills.

Some general (minimum - maximum) typical
expectations for batteries if used in deep cycle
(solar) service

• Starting 3-18 monthsMarine 1-6 years (note -
  "Marine" does not really mean anything
  official)Golf cart 2-7 yearsAGM deep cycle
  4-7 yearsGelled deep cycle 2-5 yearsDeep cycle
  (L-16 type etc) 4-8 yearsRolls-Surrette premium
  deep cycle 7-12 yearsIndustrial deep cycle
  (Crown and Rolls 4KS series) 10-20
  yearsTelephone (float) 1-20 years. These are
  usually special purpose "float service", but
  often appear on the surplus market as "deep
  cycle". They can vary considerably, depending on
  age, usage, care, and type. Most are not true
  deep cycle.NiFe (alkaline) 3-25 yearsNiCad
  (pocket plate) 2-20 years

Manufacturers of Batteries

• Concorde Sold under Sun Xtender, Lifeline,
  Chairman. Basically all the same except for minor
  differences such as terminal types. Also makes a
  wide variety of specialized aircraft (RG) and
  military types.
• Exide Many private labels. Also owns GNB.
• Rolls-Surrette Primarily manufactured in Canada,
  US manufactured batteries are sold under the
  Rolls name. Primarily deep cycle batteries for
  solar, railroad, motive power, and marine.
• Johnson Controls Primarily makes automotive
  batteries under various names. Johnson Controls
  sold their Dynasty battery division a while back
  to CD. Owns Optima Battery Corporation.
• Trojan Sells a wide variety of deep cycle and
  automotive batteries under their own name, and
  also sells to many major chains, such as Sears,
  Walmart, etc. under private label.
• US Battery Sells a wide variety of batteries
  under their own name, and also sells to many
  major chains, such as Sears, Walmart, etc. under
  private label.
• There are many more (hundreds!), for a full list

Good to know info

• Nearly all batteries will not reach full capacity
  until cycled 10-30 times. A brand new battery
  will have a capacity of about 5-10 less than the
  rated capacity.

In situations where multiple batteries are
connected in series, parallel or series/parallel,
replacement batteries should be the same size,
type and manufacturer (if possible). Age and
usage level should be the same as the companion
batteries. Do not put a new battery in a pack
which is more than 3 months old or has more than
75 cycles. Either replace with all new or use a
good used battery. For long life batteries, such
as the Surrette and Crown, you can have up to a
one year age difference.
Lead-Acid batteries do NOT have a memory, and the
rumor that they should be fully discharged to
avoid this "memory" is totally false and will
lead to early battery failure.

• Myth The old myth about not storing batteries on
  concrete floors is just that - a myth. This story
  has been around for 100 years, and originated
  back when battery cases were made up of wood and
  asphalt. The acid would leak from them, and form
  a slow-discharging circuit through the now
  acid-soaked and conductive floor.
