PulseTechPowerPulse Battery Maintenance System

I have these on all my batteries from my vehicles, electric lawn mower and my camper.

So good I bought another one!Great for situations where you have a battery that is abused (constantly charged or inconsistently charged). This one sits in my RV house battery bank (inconsistently charged when just parked, then full time charged when using the RV and at powered campsites for weeks on end), batteries are still new and powerful, absorption is great and in 4 years, haven't had to change 1 out yet. Saved $$$ (I'm not sponsored)

Not as expected, looked into and found they don't technically work as stated. Would not recommend

Works as described. Recovered my bike batteries.

Sorry for a long review. I highly recommend this product especially to the trucking community. Truck batteries are often used for hotel loads and onboard electronics. They are charged and discharged daily, causing heavier sulfation and making life expectancy of truck batteries often shorter than car batteries. By keeping your batteries healthy, this is a money saving device that can save you money from a service call for jump starting or wasting fuel idling your truck promoting unnecessary wear and tear to the engine. It will also save you money for replacing your batteries annually. I wish I knew about this product sooner so I wouldn’t have many battery problems in the past nor trying to reverse the battery problems I am currently experiencing after the damages were done.A little background about my batteries. I purchased 4 AGM batteries for my semi truck from a retail store that offers 4 years replacement warranty in September 2023. The batteries were manufactured more than a year prior to being purchased. So I didn’t have a good start there I didn’t see the batteries performing any better than the Lead Acid batteries I replaced. Here came October I took the truck to the shop for repairs. At the end of the repair they reconnected the batteries but left one cable out so one of the batteries was connected only to the starter. It was not charged with the rest of the batteries and died in a week from only starting the truck. Eventually I found the problem and hooked them up together and problem solved. Then here came November when my truck had a major problem, ended up cracking the engine head and it ended up also needing an engine overhaul. The truck sat in the shop for 3 months in the cold weather completely discharged. As soon as I got the truck back I put it on shore power which the inverter would charge the batteries when hooked to shore power but there’s one major mistake, the inverter charger setting was never changed to accommodate AGM batteries it was set to charge at 13.5V bulk, absorption and float charge. The battery was undercharged while it was sitting for another month. I wouldn’t realize it having an undercharging issue since 13.5V looked good to me. But the damages were already done the batteries are badly sulfated through sitting around for over a year after being manufactured, fully discharged and sitting in the cold for 3 months and undercharged for a month which could also have contributed to the batteries getting more sulfated.Anyways, here came when I realized I had a problem with the batteries. After I unhooked the shore power and took the truck to work, I realized when I shut the truck off, instead of dropping to 13.0V which AGM batteries should be at full charge, it dropped to 12.3V. Crank starting the engine took a lot longer than usual it took at least 8-10 cranks instead of a usual 4-5 cranks when I first own the batteries. I started searching a fix for the batteries and I remembered a Japanese product called the Nanopulser. It’s a great product I used it years ago in one of my cars until it got into a wreck and I was unable to recover anything under the hood. I looked it up and there’s no one selling it in the states anymore and the closest seller is in Canada asking for $200. So I looked into an alternative product and found PowerPulse. It is reasonably priced at less than $40 and although it’s 2x the price of those cheap Chinese products, it has an NSN number and is backed by many positive reviews. I received the product and installed one on 03/20/2024 before I got back out on the road again. The product manual says it’s best for up to 3 batteries in parallel but all semi trucks have 4 batteries so I did it anyways. There was no dramatic improvement in a short period of time but the improvement is noticeable. The sitting voltage now drops to 12.4V instead of 12.3V and it has started to take less cranking to start the engine. The batteries are plugged in and getting charged with AGM setting now and we will see how it goes. Will follow up with an update.Product installed: 03/20/2024Initial review (03/23/2024): The sitting voltage drops to 12.4V instead of 12.3V. Crank starting improvesUpdate (04/04/2024): Battery is able to sit on higher voltage momentarily when engine is turned off and sits at 12.6V. Crank starting remains strong even when battery drops to 11.9VUpdate (04/13/2024): I just took the batteries off the truck since they have capacity issues or there’s parasitic draw which need to be investigated further. Plugged in a battery tester and they all have between 925 -1000 CA even though they are at 12.05V. It proves the product PowerPulse does improve cranking power
