Optima Batteries 8027-127 D27M BLUETOP Starting and Deep Cycle Marine Battery

My overall experience with this battery has been good. Knowing a few things first will help you make the right decision. weighs a lot. 3) The battery must be charged with a device capable of charging an AGM battery. It is crucial to recharge it immediately after use, just as any other battery would. an expensive investment, and since it is a battery, it will be used repeatedly over and over backwards, so it won't last as long as a Diehard, Delco, or marine brand. A battery's life is measured by how many times it is discharged and recharged. This incremental degradation reduces its life after each use. In order to preserve battery life, it is necessary that the boat's engine has a generator circuit, in order to prevent the battery from wearing down to much. When I used it one day at Merrill Creek Reservoir, in northern NJ, with only electric outboards allowed, I had to turn around in the middle of the lake. Distances from the launch ramp to prime fishing spots can be up to a mile, and trolling can certainly put on a couple of miles. It can drain the battery more quickly if there is a windy day. It didn't last that long, but I had expected it to In fact, it yielded approximately the same amount of power over several hours of near continuously continuous use as my previous deep cycle battery did when it was new (which I bought from Walmart by the way). I still like the battery, despite all of this. This method allows a much more uniform plate separation and more surface area, so the possibility of plate shorting is reduced to a small degree. Batteries can be damaged at any time and at no fault of the owner, and that prevents their life from being as predicted. Among the best qualities of this unit are its double posts, 100% sealing, and ability to fit into a carrying case well. As well as that, you can easily clean it. My opinion on it is that you would be well served by this product, but I would also recommend you own a top-notch recharger and use it consistently When your boat is winterized for the off season, be sure to take out the battery and store it in a relatively warm place, with a battery charger nearby to give it a trickle Having not been able to touch a computer for two months The power came back to 100% in less than an hour if I charged it to the lowest Everything seems to be going well so far. Even though I know I'll be away from home for a week, I will need to recharge the battery part way through during my time away from home and find an electrical My need for a jumper cable will be frustrated if I have to pull it out of the boat and walk it to my car. I will hook the cables up for an hour while the car is Having no way of right away recharging the device if it discharges to low levels is a negative situation.

In 2017, I bought this battery from Amazon to use in our RV. During our stay, this unit was only used to operate interior lights as well as the water pump for the sink, shower etc. In one year after buying it, the laptop was completely dead. A 2 year warranty is offered by OPTIMA, and the receipt is included with the battery. There is only one seller, and that is The battery in my Kindle died, so I called Amazon customer service. I asked about it and they responded that it would be fine. The company sent me an exact replacement in April of this year. This same battery has lasted from October 2019 to October 2020. As a result, I called customer service to report that the battery I received in April 2019 had failed. It was said that when I got the replacement battery, I would no longer be covered by The battery you are looking at is not suitable for RV or Marine use. Trying something else may be better. Make sure you are aware of your warranty. Although I understand, I feel that that is not the correct approach to take. In the event that the item is defective, a replacement should be provided Despite being used properly and designed for battery usage, it was well suited to battery It's hard to beat the quality of these Optima Batteries. Since I began using them decades ago, I've never had an issue. There are some basic requirements that are not met by this model. Don't do it.

This was one of the two items I had We left our batteries in for a winter, but by the spring they had dipped below recoverable voltage and were no longer able to hold a charge. My own inattention caused the problem, so I determined that it was my own fault. purchased yet another of these and placed it on my boat (which is trailered at my house) while it is continuously charged on the The capacity will decrease to 12 after a period of about fourteen months. There is a charge of 2 volts, or sixty percent. The cost of these batteries has prompted me to go back to using standard acid batteries, which are marine in nature. It is not quite so easy for them to die. An electric vehicle that is routinely used needs a battery that is solid enough to last a long time. I do not think they are well-suited for occasional marine use, and the additional high price is simply not worth it.

In the event of a power outage, I ordered this battery to power a Pump Sentry sump pump backup. After two months of installation and no time was allowed for the battery to be drawn, the battery died. Fortunately, it is still under warranty, so we should be able to get it exchanged for free. In any case, you should be cautious of this brand if you need a backup battery in an emergency.

With my modern and classic car, I have had good performance from both yellow and red top optima batteries. In the end, I had no luck with the blue top battery purchased to run the Using the AGMS setting on a CTEK MXS 5, I have charged the battery multiple times. After 0 chargers and 11 amps of resting voltage, the charge drops to 0. In between 3 and 11, use. The charging of the first charge took just over 24 hours. Unfortunately, I waited longer than the one month return period allowed. Only the charger and test have been performed, not the device itself.

It is used in a battery backup system for a sump pump. In addition to outages and a main pump failure (while on vacation), it has been performing well. In my checks, it is still performing well after 7 years. My plan is to pull it out and keep it on a charger in case I need it in an emergency. My experience with the company over the years has been very reliable and reliable in terms of services.

My first battery failed after 2 years and the second battery failed just days after the warranty expired I called them before the 2 years and they told me to hook up a second battery and trickle charge it would not hold a charge after I disconnected it I can see on my multi-function display Watch the voltage drop every few seconds and get a Walmart battery for $95. It might last 2 years, but you are only out Since the warranty expires in a few days, they keep giving you the runaround after you get a problem, even though this is supposed to be the top rated battery by both Amazon and Optima reviews.

Amazon and Optima engaged in a dispute It was the best battery I could find. That's why I decided to buy it. This product failed within the warranty period of two years. Optima & Amazon are on the same side as me where "it's the other guys problem. ".
