Handy Remote Reset Switch
The Battery Management System (BMS) in all Hardkorr lithium batteries includes a protection circuit that activates if the voltage drops below 10.0V, preventing damage by putting the battery into ‘sleep’ mode. Previously, resetting the battery was difficult, but with Hardkorr batteries, you can easily reset the over-discharge protection by connecting the included remote reset switch to the battery and holding the button for 5 seconds. The button can also be flush-mounted into your 12V setup for convenience.

Oversized Terminals
The Hardkorr 210Ah Slimline battery features oversized terminals for easy and reliable direct +/- connections. These oversized terminals improve installation and ensure enhanced reliability for off-grid power needs.

Slimline Design for Space Efficiency
With a narrow 50mm profile, the 210Ah Slimline battery is perfect for space-conscious installations in 4x4 vehicles, trailers, or boats. Its slim form factor allows it to be mounted behind rear seats or up on a canopy wall, leaving you more room for other gear. The battery can be mounted in any orientation, and with eight brackets included, you have flexible mounting options to suit your setup.

High-Quality Construction
The 210Ah Slimline battery is engineered using high-quality aluminium-encased prismatic cells, ensuring durability and vibration resistance. At just 25kg, it’s lightweight enough for rugged travel but powerful enough to meet all your off-grid energy needs. This battery delivers 210Ah of usable power, perfect for running 12V fridges, lights, pumps, and even larger devices.

Powerful Performance
With a continuous discharge rate of 250A, the 210Ah battery can power up to 2500W from an inverter, enabling you to run your favourite 240V appliances, such as coffee machines, toasters, and induction cooktops. This capability makes it a standout choice for off-grid adventures. Plus, the Battery Management System (BMS) allows you to link up to four of these batteries in parallel or series, creating larger battery banks of up to 840Ah or systems operating at 48V.

I love it
Color: Black/Silver
I need a watch has analog display (easy for me to read) and digital function (need the alarm and the countdown) also shows the day-date (the day has to be 3 digits e.g. Sunday is "sun" instead of "su"). I know I am very demanding, but it is just me, LOL. Have bought this watch for a couple of days. Yes, it fits all my needs. Pro: 1) Light weight, fair value materials, price is low and quality is fair. The glass is just a piece of plastic which is how I felt, but I put a packing clear tape on it and cut the edge off as my home made scratch protection. 2) There are 4 push buttons, except the center one for light, the other 3 seemed like are metal with rough surface which generate enough friction to hold and push it down. 3) It has Telememo, World Time, Snooze, two daily alarms, Count Down, hourly signal, and Stop watch functions. 4) 10 years battery which is better than solar battery (if solar battery never die), or it will be more expensive to replace a solar. 5) Casio always uses 4 screws to secure the back plate, much easier to replace the battery than other brands. 6) It has a smaller case (44 mm) with a larger LED display. Neutral: 1) Telememo, I don't know who needs this, because smart phones can do much more. Also, I try not to buy a watch with Waveceptor, smart phone can always pick up the correct time right after the airplane touch down. However, Waveceptor can auto reset the watch, but the problem is if it can receive the signal? and for how long? I still prefer the old school way to manually adjust. Con: 1) There is no pull out button to set up the analog, and this watch can only go forward. For example, if analog is 2 min faster, then I have to forward the hand for 11 hours and 58 min to correct it, that is a lot of pain, even you can hold both C & D to have the hand auto advance. Or, it only need to go backward for 2 min. 2) It can show two time zones time, but the digital day-date only matches with the digital time. One can not set the day-date to match with the analog. Overall, I love this watch, and there is a metal version "AMW830D-2AV".

Nice, old school style Casio watch!
Color: Black/Silver
Nice watch for the price! It looks a lot like the old school G-Shock that I had in the 1990's. Of course it is not built like a tank like the G-Shock was. However it is a very nice everyday watch with plenty of useful functions. It even comes with a 10 year battery! Bonus! I bought the "Used, Like New" option for a VERY discounted price and it still came in the original packaging with the instruction booklet. Go ahead. Get one. You know you want to.
