• 12V 18ah Lithium Ion LiFePo4 Deep Cycle Rechargeable Battery

Now with Huge 5 YEAR WARRANTY

These lithium batteries are the future of battery storage. Lithium batteries are much lighter than traditional lead acid batteries and deliver unrivaled cycle life, more than 4 times more cycles compared to lead acid. This battery comes with a 3 year warranty.

Perfect for use in caravans, marine, camping and home storage off grid applications. Solar, wind or battery charger compatible. Designed to handle the vibration when off road. The batteries are fully sealed in a tough plastic case with a built in battery manage system for safety protection.

Lithium batteries are the equivalent to 3 similar amperage lead acid batteries and also re-charge much quicker.

You must check that your charger is suitable/adjustable for Lithium batteries, but this battery is generally great as a straight drop-in replacement for your existing 12v AGM or Gel deep cycle battery!
