8. Trojan T-105 Plus

When you’re talking about deep-cycle flooded lead-acid batteries, the Trojan T-105 Plus is a name that often comes up. These batteries are known for their durability and reliability, making them a popular choice for off-grid systems, especially those on a budget. They’ve been around for a while, and their track record speaks for itself.

The Trojan T-105 Plus is a workhorse, designed to withstand the rigors of frequent charge and discharge cycles. They aren’t the flashiest or most technologically advanced option, but they get the job done. They’re a solid, dependable choice if you’re willing to put in the maintenance required for flooded lead-acid batteries.

Here’s a quick rundown of what you should know:

• Voltage: Typically 6V, so you’ll need to wire them in series to achieve higher voltages (like 24V or 48V).
• Capacity: Around 225 amp-hours at a 20-hour rate. This means you can draw about 11.25 amps continuously for 20 hours.
• Lifespan: With proper maintenance, you can expect several years of service. Regular watering is key to maximizing their lifespan.

One thing to keep in mind is that flooded lead-acid batteries require regular maintenance. This includes checking and refilling the water levels with distilled water. If you neglect this, you’ll significantly shorten the battery’s lifespan. Also, they need to be stored in a well-ventilated area because they release gases during charging.

While they might not have the energy density or maintenance-free convenience of lithium batteries, their lower upfront cost makes them an attractive option for some. Just be prepared for the extra work involved in keeping them running smoothly. For those seeking sustainable and renewable energy, it’s important to consider all factors.
