Models with a Lithium Battery
The lithium battery on the Tive devices have a minimum of 500 recharge cycles. If the device is recharged and reused every week, this would represent a minimum of 500 weeks (over 9 years). After this time, the battery will continue to work however the battery life will be reduced slightly. This applies to the TT-5000, TT-5010 and TT-7000 models.
Models with a Non-Lithium Battery
The Nickel based battery (NiMH) have a minimum number of 300 recharge cycles. This means that the battery can sustain 300 full discharge-recharge cycles, roughly over 5 years. This applies to the TT-7100 tracker model.
