Usable capacity – “Lead-acid” batteries cannot compare with lithium batteries for capacity. Lithium allows for 85% rated capacity whereas lead-acid allows for about 30-50%. For example, using 100-amp hour battery. Lead-acid equals 30 to 50 amp hours of usable juice, but lithium provides 85 amp hours or more!
Long cycle life (discharge/charge cycle) – The best deep cycle lead-acid batteries provide 500 – 1500 lifecycles. However, a well-cared for lithium can provide 2000 -3000 lifecycles. The results speaks for itself.
Ultra Fast charging – Lithium batteries charge “fast” to 100% of capacity. Unlike lead acid which needs to slow down during an absorption phase to get the final 20%. Contrary to lead-acid batteries, lithium is usable without a full charge. Lithium is a great choice for boaters using solar recharging systems on cloudy days.
Built-in overcharge protection – Lithium batteries have a built-in protection system (BPS). This protects the battery from low charge, overcharging, short-circuiting and reverse polarity. This extends battery life and lowers premature replacement costs.
Lightweight – Lithium batteries are feather light, much more than compared to lead-acid. In fact, lithium is four times lighter! As a result, installing and replacement are much easier for lithium.
No placement problems – Like AGM or Gel, Lithium can be place in any orientation. This is useful if you have an existing battery bay with limited space. Or when upgrading from the capacity of older lead acid batteries.
Cold temperature resistance – Lithium-ion batteries are much more efficient at low temperatures. At -20°C, a Lithium battery can deliver around 80% of its energy capacity, whereas an AGM battery will deliver only 30%. For harsh environments, Lithium is a superior choice.
