A lead-acid gel-cell battery would be the best choice, unless weight is critical
,
in which case you might want to look at Nimh (Nickel-metal hydride) or Lithium-i
on
batteries, but the gel-cell will be cheaper, and can be float charged with const

voltage. The others require fancy charging circuitry. A "gas-gauge" for a gel-ce

basically a voltmeter.
