How Long Will A Home Battery Last? Should You Even Buy One?

——litharv give you answer

A home battery backup system can keep your devices powered during an outage. But how long does one last and is it worth the investment? Find out here.

Batteries are a convenient tool to store energy and power your home during an outage, but unfortunately they do have a limited life span. You’ll have noticed that with your smartphone, the battery’s charge diminishes over time and you have worse battery life over time, which means plugging in your phone more often.

This behavior isn’t exclusive to just your smartphone battery. Pretty much all systems will see their battery capacity reduce over time, and eventually need replacement. The same goes for home batteries, which are giant lithium-ion batteries that act as a backup power source for your home. They also have a limited lifespan, and aren’t immune to the inevitable demise their smaller counterparts face.

Factors that can affect your home battery’s lifespan

Not all batteries are created equal — and even batteries that are similar won’t all last the same amount of time. That’s because several external factors can affect your battery’s lifespan. Here are a few things to consider. 

Exposure to extreme temperatures

Sometimes the things that can affect your battery’s lifespan are things that are completely outside of your control, like the weather. If you live in an extremely hot or cold climate, that can shorten your battery’s lifespan, McDonald said. When you’re thinking about where to put your battery, try to keep it somewhere that reduces its exposure to temperature extremes. 

If you live in a hot climate, keeping it indoors, or at least somewhere shaded, can help your battery last longer. If you live in a cold climate, keeping it insulated from the elements will also help. If your home has a garage, consider having it installed there.

Depth of discharge

The way you use your battery can also affect its lifespan. A battery’s depth of discharge refers to the amount of energy you can safely drain relative to its maximum capacity. If you drain your battery all the way to zero before you recharge, that can actually hurt your battery, McDonald said. Many battery systems won’t even let you discharge that far for this precise reason, as a way of protecting battery health.

Number of charging cycles

Battery lifespans of 10 or 15 years assume that you’ll run a certain number of charging cycles. Each time you drain and recharge your battery, it reduces the lifespan a little bit, according to McDonald. 

So if you end up cycling your battery more than what’s recommended by the manufacturer, you might end up with a lower-than-average battery lifespan. “It gives wear and tear,” McDonald said. Check your battery’s warranty to see its expected cycle life.

Physical damage

It probably goes without saying, but you’d be surprised how easy it can be to accidentally damage your battery. McDonald said he’s seen several people bump into their battery with their car while pulling into the garage. If you damage your battery like this, it’s probably going to reduce its lifespan. When scoping out a location to install your battery, work with your installer to find a spot that’s both easy to access and has a low risk of accidental damage to the battery.

What should I use during a power outage: a home battery or a portable generator?

If the upfront cost of installing a battery-based power backup system isn’t feasible, a portable generator is a solid quick fix. However, in the long run, getting a home battery system that’s powered by solar can be the ideal fix to safeguard against power outages.

Home batteries might not be the right decision for everyone. If you can’t stomach the high upfront costs, aren’t worried about potential power outages or can’t take advantage of time-of-use rates, then a home battery might not be worth it.
