My car hasn't been started in several months, which has a Optima red battery in it. Electricals work, but the starter will not engage. I popped my battery on the charger for a while and it shows that it has a full charge. Still have the same starting issue, it could be the starter - but I guess I will ask if these batteries can lose cells like a conventional one. I'd hate to shell out $140 and find out that is not my problem. How can I check this, check power at the terminals with a DVM while someone turns the key??

If you are putting a fresh battery in the 914 and it still won't start then the battery isn't the problem.
Your optima could still be discharged after letting it sit for 3 months. Optimas have special charging procedures when it is fully run down. They supposedly need a high amperage shock charge followed by a trickle charge to get them going again. I found this on the Optima web site: 34 & 34R - 34/78 - 6V - 25 & 35 - 75/25 These batteries are designed for engine starting applications. They are NOT recommended or warranted for use in deep cycle applications. Recommended charging information: Alternator: 13.3 to 15.0 volts, no amperage limit. Battery charger: 13.8 to 15.0 volts, 10 amps maximum, 6-12 hours approximate. Rapid Recharge: Maximum voltage 15.6 volts (regulated). Maximum current: No limit as long as temperature < 125°F (51.7°C). Maximum recharge time: Charge until current drops below 1 amp. Float charge: 13.2 to 13.8 volts, 1 amp maximum current, time indefinite (at lower voltage). I also highly recommend a CTEK battery charger/maintainer for cars that aren't used every day: http://www.ctek.com/US/chargers.asp I have the US800. Works awesome. |
