12V 130AH SB LM130 Heavy Duty Deep Cycle Leisure Marine Battery Caravan Motor mover Motorhome Boat Boathome Yacht Camper

Fitted and working well. Haven't had fitted long enough to comment on their longevity. The batteries show the terminals as positive to the left, they actually arrived with the terminals mounted centrally on the batteries ?

I have 6 in parallel in a Sprinter van charged from 400W solar and split charge from engine.During the RV conversion, the guy doing the work abused the batteries by plugging his power tools into the inverter taking them below the minimum threshold (potentially dangerous). However, batteries have still not let me down - although the winter time doesn't yield enough sunlight to use them as per design and power is inadequate after a couple of weeks without a mains charge.Interesting comments from a fellow shopper about weight to charge ratio, will take into consideration before replacement.

I bought 2 of these to go into a 300w off grid solar cabin setup, they seem to hold the charge well and are performing as expected. Good value all round.

These heavy beasts are rated at 120 Ah (C100), where the C100 rating translates to the industry standard C20 rating at 80% efficacy. So these "120 Ah (C100)" batteries have ACTUALLY only "96 Ah (C20)" capacity (discharging at 5 Ah, or 60 W), which is LOWER than any other brand at 100 Ah (C20)! In practice, it is even worse than that: my measurements suggest a twofold lower rating of ~50 Ah (see below). I wonder why people care about the size and weight of these, while it is only the actual discharge time in a regular application that matters.Bought two of these (2 x LM 120 Ah) to use in my garden solar system (2 x 140W panels) driven by a sophisticated hybrid inverter (Iconica 2000W). Since the inverter is constantly connected to mains and, hence, acts as an automatic switch between solar system and the mains whenever the battery bank needs to be recharged (with a 3 stage smart charge controller), the setup is equivalent to the RV/caravan system. Considering the moderate load of only 60 W (max) due to my fish pond (pump + UV lamp) plus some LEDs in evenings, these batteries should have been more than enough to run the load through nights when no solar PV input is available.Simple calculation: 2*120 Ah *12V = 2880 W in total. For the sake of extending the battery life, planned to take only half of it (allowing only half-way discharge down to 12.4 V per battery), then dividing by 60 W, one gets: 0.5*2880/60 = 24 hours. Now, correcting for the losses in the inverter (90% efficiency) and the C20 rate instead of C100 (stated on the batteries): 24*.9*.8 = 17.3 hours (at least, beacuse the LEDs are only used occasionally).So, the two LM120 batteries should have been able to provide continuous run for my 60 W load for at least 17 hours, which would only drew half their charge capacity. The calculation did not even include any extra power from the solar panels. - In practice, upon installation and full recharge these batteries could only run my load through a short May night (about 8 hours) and then another couple of hours with support from the solar panels - 10 hours overall, and then needed a recharge. That is half of the expected run-time!O'kay, I still decided to keep them, not to go into the hassle of replacement, thinking that it is kind of satisfactory: the nights were served, and the bright sunlight during the heat wave summer helped to keep the charge up around 25-26 V until dusk. The inverter switching to mains whenever needed served as a great charge controller (but also doing regular equilisation maintenance for the batteries, every two weeks or so). So I thought my system and batteries work fine and healthy - until recently when the normal British weather "kicked back" with the greyish days and raining.Now, after about 4 months, these batteries can only support the load (tested without solar input) for about 5 hours, which implies a twofold drop in capacity!What a disappointment are these "Super-duper heavy duty" LM120 rubbish after all.

I deliberated long and hard before buying this Battery for my project, if you are thinking of a powerhouse battery for use in virtually any project, this will do the job!This thing pushes out some serious power, I've connected it as a second battery, with fuses and an Split Charge Relay, and after changing something i forgot to engage the switch on the fuse to connect it back to the main battery and the alternator, so i was running the battery for most of the day without it getting any charge, and I was mercilessly abusing it, (Seriously)later i remembered the switch, and thought the battery would need a trickle charge, but when i connected the charger, the battery was still 99% charged NO PROBLEM. THIS IS A SERIOUS HEAVY DUTY BATTERY, (If anyone thinks i am wrong, i challenge you to come check out my setup, anytime)I can see if looked after this will last for years and years.... well done SuperBattBy the way price and delivery was excellent, so thanks AMAZON

As described and fast delivery

I ordered 4 to create a 12v 570 AH battery bank connected to a 1500w 12v to 230v inverter. . Ensure that you have good charger to get the terminal voltage to 14.40v. Needs good ventilation - slightly pungent fibreglass whiff when on Boost charge. Have not fully tested out the capacity but appears to be fine on initial loads.

As the headline, this worked fine for 11 months, being used in a light use off-grid solar setup. Unfortunately, it seems that one of the cells in the battery isn't working any longer. The inverter will still work with a ~10.5V setup but the controllers refuse to deliver 12V load with it.A real pity.
