Batteries. PMNN4412 and PMNN4415AR: Lithium for handheld two-way radio without memory effect

How Lithium Differs from Nickel in Daily Work

Nickel-metal hydride batteries, which we have already discussed in the technical guide HNN9009, have a rule of smooth cycle: worked shift - put on night charging. Lithium-ion PMNN4412 and PMNN4415AR Li-Ion has no memory effect, and two-way radio can be recharged at any time - at least fifteen minutes between flights. For change with breaks it is more convenient: the battery does not require bringing to zero and does not spoil from short recharges.

Two configurations for two tasks

The PMNN4412 is a standard lithium-ion battery: its capacity is enough for a normal working shift with a margin for negotiations. The PMNN4415AR is a high-capacity configuration, and the difference is felt precisely on long shifts: when two-way radio is on the belt from morning to night, there is no place to recharge it, and the channel is occupied constantly. The rule of choice is simple: shift up to ten hours - take the standard, the change is longer or the connection is tense - increased capacity. In a pair, they close both scenarios, and many brigades hold one copy of each.

How to Charge Lithium to Live Longer

Li-Ion has two enemies: deep discharge and heat. Deep discharge - when two-way radio turns off itself: such cycles noticeably eat up the resource, so the battery on the belt is changed, without waiting for an automatic shutdown. Heat is a summer car cabin under the sun and a battery forgotten at the heater: it is better to store and charge lithium at room temperature. In winter, lithium yields less capacity than nickel in the cold – if you work mainly in the cold, see also the nickel-metal hydride HNN9009 for GP340: it is more predictable there.

Compatibility: Compatible by series

The seat and battery contacts of different Motorola series have their own - a visually similar battery of a neighboring model may simply not sit down or give contact. Therefore, as with other accessories, before ordering, we check compatibility on your two-way radio list: send models - we will confirm the appropriate configuration by letter to exclude returns due to a mismatched seat.

What to take with batteries

It’s smart to add a charger to each new battery—so charging in breaks actually works, rather than remaining an intention. For the park handheld two-way radio GP340 cases are useful: they protect the body and mounting of the battery from erasing on the belt. All this is available, the positions in the block "Available" below.

How to order
