TROLLTEK (“the Manufacturer”) warrants each TROLLTEK Lithium branded Lithium Iron Phosphate (LiFePO4) battery (“the Battery”) sold by or any of its authorised distributors or dealers, to be free of defects for a period of 5 years (“the Warranty Period”) from the date of sale as determined by either the customer’s sale receipt, the shipping invoice and/or the battery serial number, with proof of purchase.

The Manufacturer will credit, replace or repair, if serviceable, the Battery and/or parts of the Battery.


If a battery is deemed to be unrepairable, the Manufacture may choose to offer a pro-rata warranty solution. In effect the amount of time you have used (received value from) the battery that you are claiming warranty on will be taken into account when replacing the battery under warranty. 

For example:

After testing, Trolltek have agreed that your battery is claimable under warranty.

From the date of the original Tax invoice it can be ascertained that you have received 12 months of service from the battery that is now faulty.

The now deemed faulty Battery has a 5 Year Warranty.

There are 60 Months in a 5 year period.

At the time of claim the recommended retail price for a new battery of the same type and size is $1,000.

Therefore $1,000 divided by 60 months = $17 per month

You will need to contribute 12 Months x $17 = $204 towards the price of a new battery.

Your replacement battery will receive the full 5 Year Warranty and will be treated as new.

The lifespan of each TROLLTEK Lithium battery depends on the application and use. This warranty ensures that all batteries are free of manufacturing defects for 5 years.

Depending on use, Trolltek Lithium iron phosphate batteries may have a lifespan that is longer or shorter than the 5-year manufacturer defect warranty. Trolltek
Lithium’s LiFePO4 technology uses cells with a half-life exceeding 6,000 recharge cycles (Half-life is 50% depth of discharge, which means the cells have half the capacity when full), this is approximately 12 to 15 years at regular use. 12 to 15 years is the maximum usable lifespan possible under optimal conditions and customer care. Trolltek advertises the minimum expected lifespan of 6 years, or roughly 2,000 recharge cycles at regular use – 4X the recharge cycles of lead acid batteries.

The lifespan of the battery may vary depending on the application. Customers are encouraged to follow the recommended specifications for charging, storage, and use – if treated well a Trolltek Lithium battery will last a long time. Typically charging with a lithium specific charger, charging at a lower amp rating
(0.2C or lower), not charging below freezing, and lower discharge applications may result in a longer lifespan. Higher discharge applications, including air-conditioning units, electric vehicle applications, and applications listed in the warranty exclusions below will result in a shorter lifespan. Abuse of the battery,
including discharge above the battery specifications, is not covered under this warranty (see warranty exclusions below).

This Limited Warranty is to the original purchaser of the Battery and is not transferable to any other person or entity. Please contact the place of purchase regarding any warranty claim.

The Manufacturer has no obligation under this Limited Warranty for Battery subjected to the following conditions (including but not limited to):
• Damage due to improper installation; loose terminal connections, under-sized cabling, incorrect connections (series and parallel) for desired voltage and AH requirements, or reverse polarity connections
• Environmental damage; inappropriate storage conditions as defined by the Manufacturer; exposure to extreme hot or cold temperatures, fire or freezing, or water damage including submersion
• Repeated exposure of terminals to saltwater without use of dialectic grease and rubber terminal covers.
• Damage caused by collision
• Damage due to improper maintenance; under- or over-charging the Battery, dirty terminal connections
• Battery is wired in series to create a battery system with a voltage greater than 48V (max limit for series connections is 4 x 12V units = 48V).
• Battery that has been opened, modified or tampered with
• Battery that was used for applications other than which it was designed and intended for, including repeated engine starting or drawing more amps then the battery is rated to continually discharge in the specifications
• Battery that was used on an over-sized inverter/charger (any inverter/charger that is rated to 3500 Watts or greater) without the use of a Manufacturer-approved current surge limiting device
• Battery that was under-sized for the application, including an Air Conditioner or similar device having a locked rotor startup up current that is not used in conjunction with a Manufacturer approved surge-limiting device
• Battery that has not been charged for over 1 year (batteries need to be charged regularly to allow for a long lifespan)
• Charging the battery when the battery temperature is below 0°C
• Battery not stored in adherence to the Manufacturer’s storage guidelines, including storage of the Battery at low state-of-charge (charge your battery to full before storing)
• This Limited Warranty does not cover a Battery that has reached its normal end of life due to usage which may occur prior to the Warranty Period. A battery can deliver only a fixed amount of energy over its life which will occur over different periods of time depending on the application.

For example, cycling the battery more than 1 time daily, will cause the normal end of life to occur before the end of the Warranty Period. The Manufacturer reserves the right to deny a warranty claim if the Battery is determined, upon inspection, to be at its normal end of life even if within the Warranty Period.
