Get-go, why cull a 100ah battery?

Nosotros've written earlier on why a deep bicycle battery is the mode to go, simply what makes a 100ah deep cycle bombardment a ameliorate selection than a 35ah, or 155ah battery? Clearly, the higher amp hours means the larger the energy storage of the battery itself, but it also means a pricier product. Whether you're running a simple solar setup, or plan on charging your 2nd bombardment via a battery isolator, nosotros've constitute that 100 amp hours gives the average van dweller an platonic combination of energy and toll. Information technology's mostly completely sufficient to run LED lights, charge cell phones/tablets, and run minor accessories via an inverter. (Notwithstanding, if you need to run large appliances consistently, like a 12V fridge or a modest air conditioner, y'all may consider an fifty-fifty larger battery, or multiple run "in parallel").

What does 100ah really mean?

If you're new to 12V batteries in full general, you may wonder what these numbers mean. "AH" stands for "amp hours", and merely put, 100ah means that a battery can deliver i amp of current at the rated voltage (12V in this case) for 100 hours. Or, alternatively, 2 amps for fifty hours, or 4 amps for 25 hours or 100 amps for 1 60 minutes and and then on.

Some other fashion to view it (which might be handy when reviewing the appliances/electronic you programme to power:
A 100ah battery volition provide 1 amp X 12 Volts = 12 Watts for 100 hours. On the high end, 100 amps X 12V = 1200 Watts for one hour.

highlight-arrow Important: In gild to maintain the lifespan, 12V batteries like these should never exist tuckered past fifty% accuse. So, while it may technically power 1200 Watts for i Hr, y'all should only power 600 Watts. If y'all discover that you lot need the accented, full chapters of a 100ah battery, you'll need to buy two batteries.

So what makes one 100ah battery better than the next?

Deep-cycle batteries like these are powered past chemical reactions safely located within the battery itself. Specifically, they role by acid interacting with a number of metal (atomic number 82) plates. The quality of a item 100ah deep cycle battery will depend on the quality/strength of the components used and the design of the interior of the battery (which the consumer really won't be able to see). Generally the "best" deep cycle batteries will be those that provide consistent, prophylactic ability for as many charging cycles every bit possible over information technology's lifetime.

The following 100ah 12V batteries have been proven to exist reliable, take thousands of charges reliably, and provide consequent levels of ability.

Our Choices:

Key feature: High charge wheel count, used with solar often

1. Renogy Deep Cycle Pure Gel Bombardment 12V 100Ah

The heavy-duty lead-calcium grids within this bombardment are meant to last upward to 10 years, and the PE compound separator design distributes gel electrolyte evenly through the battery's interior, meaning maximum consistency in output.

What's amazing about this GEL model is that compared to the Renogy AGM 100ah battery, it can handle almost double the charge cycles (1100 vs 600 in the AGM model). However, if you need high bursts of amps (like using a power tool), y'all should generally opt for an AGM battery over Gel.

The battery'south design is safe in that it doesn't off-gas or leak, and has a low self-discharge rate of iii% per calendar month, meaning if y'all go out it sitting in a cupboard for a year, it will still accept ~60% charge.

This Renogy battery is often paired with the Renogy Solar Starter Kit, so it's needless to say that they are used often in RV and DIY campervans worldwide.

Central feature: Affordable, no-frills

2. Universal 12V 100 Amp-Hour AGM Battery

This battery is the "Honda Civic" of 12V AGM batteries. It'southward super affordable, and simply works. Information technology's also the 1 we've used successfully in our van for over a twelvemonth. It might look like it was taken out of a military surplus shop, but it'south a very condom and secure AGM battery.

Backed by a full one-year warranty, this battery is designed for maximum deep cycle performance in specific environments of discharging and recharging several times (perfect for van use). Information technology may not offer the loftier amount of charge cycles as others on the list, but if yous're on a tight budget, you tin't get wrong with the Universal.

Central characteristic: Operates in a wide range of temperatures

3. Mighty Max 100AH BATTERY FOR SOLAR

The Mighty Max is a Sealed Lead Acrid/AGM battery that provides consistent ability at another attractive price (like to the Universal above). Information technology resists high vibrations well, and operates reliably at a wide range of ambient temperatures.

1 thing worth noting about the Mighty Max are the user reviews that claim the terminals (the metal posts to with yous attach your wiring) may be too breakable, and have occasionally cleaved when someone torques down a bolt also tightly. We can't verify this merits, (and you shouldn't torque down too tightly regardless), but countless have used the Mighty Max with glowing reviews.

Cardinal feature: Top-tier quality and performance

4. VMAX 12V 100 Amp-Hour AGM Battery

This is the big daddy. Information technology's the virtually expensive on the listing, clocking in near $35 more than than the next expensive option, but for good reason.

The VMAX 100ah battery takes a charge faster than whatever others listed here, and delivers loftier-quality output on a grand scale. We've seen a good number of reports claiming the VMAX lasts up to x years without having to be replaced, with up to 1500+ charge cycles, which is incredibly impressive if truthful. It performs in both high-amp, short burst applications, as well a low & slow power needs.

If you think y'all may forget/disobey the 50% charge dominion oftentimes, then yous'll need a bombardment that offers a bigger buffer of charge cycles like this one. And if yous treat your batteries right and want consistent, long-lasting power for years on cease, it'southward hard to beat this battery.
