Intro:

Upgrading to lithium batteries from traditional lead-acid batteries can be a game-changer for anyone who relies on battery power. Whether you're powering your caravan, boat, or off-grid home, lithium batteries offer a number of advantages over their lead-acid counterparts.

Compact Power:

First and foremost, lithium batteries are much lighter and more compact than lead-acid batteries. This means you can pack more power into a smaller space, which can be a massive advantage if you're working with limited space. Lithium batteries are much more efficient than lead-acid batteries, meaning you'll get more power out of each charge. This can be especially important if you're relying on battery power for extended periods of time. TITAN Lithium boasts the best size-to-capacity ratio on the market with our 80Ah, 100Ah and 120Ah batteries all being in much smaller battery cases than the competition.

Huge Lifespan:

Another significant advantage of lithium batteries is their longer lifespan. Lead-acid batteries typically last between 3-5 years, whereas lithium batteries can last up to 10 years or more. This means you won't have to replace your batteries as often, which can save you a lot of money in the long run. While our batteries have a design life of 10 years, due to our exclusive custom cell and BMS quality, our expected lifespan is more like 20 years for the average user.

Cost:

As an example, we'll use our 150Ah. Despite its high initial cost, TITAN lithium is cheaper than its lead-acid counterparts over its lifespan. Our design life is 10 years - this battery costs £750 or £75 a year. The closest capacity equivalent in lead-acid is the Exide AGM EP2100 with a design life of 4 years - currently around £520 or £130 a year (replacing the battery at the 4 year mark). This equates to £550 in savings over a 10 year period, plus all the benefits of a lighter, smaller and more efficient battery.

Safety:

Finally, lithium batteries are much safer than lead-acid batteries. Lead-acid batteries can release hydrogen gas when they're charging, which can be a fire hazard. Lithium batteries, on the other hand, are much less prone to this type of dangerous behaviour due to their built-in system, consider switching BMS that controls the battery, and will ensure no damage can occur should the battery be used to its extremes.

Conclusion:

Overall, upgrading to lithium batteries is a smart move for anyone who relies on battery power. They offer a number of advantages over lead-acid batteries, including lighter weight, greater efficiency, longer lifespan, and improved safety. So if you want to upgrade your battery with TITAN lithium batteries - the UK's longest-running, family-owned battery specialists.
