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??

Yup, that's one easy way to do it. Check across the battery terminals and that'll check the battery. I forget how low the voltage can drop under the starter's load, but if it goes to <9V, it needs some "help". (Try recharging it on the 6A setting for a while; sometimes that seems to help with Optimas!)
Checking at the starter will tell you if you've enough voltage getting to the starter--which checks all of the wiring, the ignition switch, the grounds, etc. --DD |
