5 Best Group 51 Battery (Tested) 2023

1. Optima Batteries 8071167 D51 YellowTop Dual Purpose Battery

This is the battery that I have been using to power my 8171767 DS46B24R Prius, and it has been holding up well.

I replaced the stock battery and had the Optima battery installed about two years ago, and it has never failed me yet. The Optima battery is hard to find now, but I ordered one from Amazon and had it shipped to my door within 24 hours.

This battery is designed for off-road use, so it’s not meant for daily driving. It’s also vibration resistant and spillable so that it won’t spill or leak. The Optima battery comes with a maintenance-free deep cycle protection circuit, which means it will not fail after a few years.

I’m also happy to report that the Optima battery is very maintenance-free. You don’t have to do anything to it except charge it occasionally. You should be able to get about 200 miles per charge.

The Optima battery can handle a lot of abuse, but it’s not recommended for daily driving. For that, I recommend the Duratrax EZStart Battery.

Overall, the Optima battery is a great addition to my Prius. It’s reliable, holds up to daily driving, and is easy to replace. I highly recommend it to anyone who needs to upgrade their car’s battery.

2. Delphi BU905P MaxStart A.G.M. Premium Automotive Battery, Group Size 51P

This is the battery I’ve been waiting for! I’ve had a lot of trouble with my old battery, and my previous battery lasted only four months before it died.

I was getting ready to buy another one when I stumbled across it, and it’s exactly what I was looking for. I’ve owned my current battery for about two years, and it’s still strong.

The extended cold-cranking amps are perfect for today’s modern electronics, and the 325 CCA is enough to get my car started in the morning and drive around town all day.

The 60 R.C. is also great for my daily commute, and it’s nice to know that my battery can handle the extra stress.

The Delphi battery has 20x the vibration resistance of conventional batteries, making it the best car battery choice. This battery is also highly resistant to corrosion and extreme temperatures.

This battery is made from stainless steel, which is a better choice than the zinc-carbon batteries that most others use.

The battery has a sealed housing with a manifold venting system. This design is safer than the exposed venting system and reduces the chance of acid leaking into the environment.

The Delphi battery has a group size of 51P, and it’s made for vehicles with a 12-volt battery and a standard gauge.

I’ve had my Delphi battery for about two years now, and I’m still using it so that it will last much longer than my old battery.I highly recommend this battery to anyone who wants the best, longest-lasting battery possible.

3. ACDelco ACDB24R Advantage A.G.M. Automotive BCI Group 51 Battery

Many truck batteries have a 24-month warranty, but most are only covered for six months.

It’s designed to protect your truck battery from the elements and to increase its durability. With this battery, you can enjoy longer-lasting power and save money on maintenance.

AGM batteries are ideal for electric vehicles because they have a higher capacity, which means they can handle more power. This is particularly important for electric cars as they need more power to run the motors and charge the batteries.

XS Power is one of the world’s best manufacturers of solar batteries.

They’ve made a name for themselves with their high-quality and reliable batteries, which have been around for over 25 years.

2) Its high capacity and low internal resistance provide constant current at any given voltage.

3) It has an M6 terminal bolt, which can easily connect to a solar panel.

4) It has a life expectancy of 50 years, and a 5-year warranty also covers it.
