I use Optima Blue Top batteries as a power backup with a pure sinewave inverter/charger. They are powerful and can be mounted at any angle since they are sealed and don't vent gas like a flooded battery. Being sealed, the posts don't corrode like regular batteries and the can be used indoors with care. When under a load they hold at 12 volts for a long time and recharge much faster than most batteries and do not heat up even when charged fast, like 70 amps. Optima could package them a little better for shipping one was cracked at the bottom. A piece of stryofoam in the bottom of the box would have saved it from damage. Amazon did send a replacement. Thanks.

Awesome battery which does not require a whole lot of charging to keep it topped off when setting during the winter months; I have a regular WalMart Deep Cycle battery for starting and it does require alot of changing. Recovery time after a full day of fishing is much less than regular deep cycle batteries. If you are a fisherman and want a battery the will deliver this is it but if you are running one of the larger trolling motors purchase the next step up in this battery. Well worth the money.

Optima Batteries 8016-103 D34M BlueTop Dual Purpose Battery

I read this was the ultimate Optima battery for my RV. I ordered one, but the poor packaging by Amazon resulted in a severly cracked battery, exposing the core, when it was delivered. I have read other customer reviews stating their battery was damaged when delivered. Is not transporting or delivering a cracked battery a bio hazard? Customer Service quickly and cheerfully refunded my money because there were no more in stock. Now that the stock has been replenished the battery costs more and I am not sure if it will not arrive damaged. Amazon should read the reviews and package properly.

Amazon has not corrected the packaging problem with these batteries. The battery arrived in a box with a single layer of bubble wrap over the top of the battery. The top of the battery was cracked and the cells inside were visible. I purchased this battery to replace a blue top optima I have had for 8 years. The best battery I have ever owned! I used it for everything from powering 12volt lights in a cabin, to the only power supply in my rock crawler that has a 8k lb winch, 3k lb winch, off-road driving lights, 6 auxiliary lights, air compressor and 300 watt stereo system. I highly recommend the battery, however...do not buy it from amazon. I did get my money back. At first the rep said they could only refund half. I said that was unacceptable and they agreed to a full refund.

Great battery for what I needed. Fits great in my little john boat and has plenty of power for my trolling motor. It is a little heavier than I had expected but still lighter than most batteries. Also was received very quickly as usual with stuff I have ordered from Amazon. I would recommend this battery to all avid fisherman definitly worth the money!
