Pros

The Optima Batteries 8006-006 34M BlueTop is an excellent starting battery. It delivers 800 cold cranking amps and 1000 A marine cranking amps, giving it excellent performance even in frosty winter weather that would affect the performance of other batteries.

Since this is an AGM (absorbent glass mat) battery, it requires no maintenance. It also charges fairly quickly, reaching a full charge in six to 12 hours. If you’re looking for a battery that’s easy to care for, the 8006-006 34M BlueTop fits the bill.

Since this is a starting battery, it does an excellent job of starting outboard motors, cars, small trucks and RVs. It’s also a very good battery for powering electrical equipment on your boat or RV, ranging from navigation systems to appliances, electrical devices, and hi-fi systems.

Because of its thick plastic case and SpiralCell technology, this battery is extremely resilient and durable. Optima claims it’s 15 times as resistant to vibration as other batteries — a claim we feel confident in after seeing its exterior and checking its quality.

Finally, this battery has an excellent warranty. Optima guarantees that it will be defect-free for at least 24 months after purchase and will provide a free replacement service through Amazon for any damaged or defective batteries.

Cons

Since this is a starting battery, it doesn’t offer good deep cycling performance. If you need a dual purpose battery that can start and deep cycle, it’s best to pick up a dual purpose BlueTop (which comes in a light gray case) or a YellowTop battery.

Finally, because this battery uses AGM technology, it needs to be charged carefully to prevent accidental damage.

Verdict

The Optima Batteries 8006-006 34M BlueTop is an excellent starting battery that will serve most boats, cars, and RVs well. Just make sure you also have a reliable dual purpose or deep cycling battery available if you need to power a trolling motor.
