Subject: Re: Leak Free Battery (fwd)
The optima has really great CCA but
--they won't have a deep-cycle version until a year from now (they told me
on the phone three weeks ago), and,
--the reserve capacity seems to be less than you would think for this rating
of battery (can't remember the details now)
--my buddies in the 4x4 world seem to really like this battery

>> There is a leak-free (so they claim) car battery, the Optima.
>> Is uses a significantly different construction than

>>
>> Claims:
>>
>> Can be charged at 20 Amps in 2.75 hours.
>>
>> No vibration-caused failures.
>>
>> Lasts 3-4 times longer.
>>
>> Can be operated in any position, even upside down.
>>
>> Zero-maintenance, no corrosion.
>>
>> Longer shelf life. ("months")
>>
>> 2 year full replacement warranty, remainder of
>> 72 months pro-rated.
>>
>> 800 Cold cranking Amps
>> Reserve capacity: 120 minutes
>> 9 15/16" x 6 3/4" x 7 13/16"
>> 39 pounds
>>
>> For Corrados, you want the 800S model. There is also a
>> 800U model with both top and side terminals, and a 850/6
>> 6 Volt model.
>>
>> I bought one of these last week. So far so good.
>>
>> The spec is a bit taller than the stock "group 41"
