It is very important to maintain your batteries correctly so as to ensure a good charge and long life. This is especially true if not using your radio / battery most days.
Please follow these charging tips to ensure your battery is kept in good health:
a) If left attached to a radio it is best to recharge the battery as soon as possible after use, but in any case no more than 7-days. Please re-charge every 7-days if stored un-used on the radio (we strongly recommend storing un-used batteries off the radio).
b) For batteries left in storage off the radio, we recommend a monthly multi-meter voltage check to decide if they need topping up. If voltage drops below 7.0V, batteries should be recharged. Typically it takes it takes 3 months for a battery to self discharge from 8.0V to 7.0V.
IMPORTANT SAFETY NOTES
DO NOT:
Use a battery that is in any way damaged.
Discard of your battery in a fire or apply any direct heating source.
Dismantle or in any way damage your battery.
Carry charged batteries where the batteries contacts may be shorted by metal objects, e.g. in a pocket or bag etc.
YOU MUST:
Follow all Entel instructions with regards battery safety, care & operation.
Prior to charging or use, carefully dry wet batteries using a microfiber or lint free cloth.
Only use Entel chargers.
BATTERY CARE – DAY TO DAY USE
So as to ensure a good charge & long life, it is very important to maintain your batteries correctly. This is especially true if not using your radio / battery on a regular basis:
You must charge the battery before first use or within 3-months of receipt, whichever is soonest.
Recommended charging temperature is 10C to 40C.
Short term storage temperature range is -20C to +60C. Please note, these are the extremes, see long term storage temperature range below for ideal conditions.
When the battery is charged / stored attached to a radio:
o The radio must be switched off during charging.
o For DX & DT radios, re-charge prior to use, or within 30-days, whichever is soonest*
o For DN radios, re-charge prior to use, or within 7-days, whichever is soonest*
* When not being used on a weekly basis, we strongly recommend storing the battery off the radio (see below).
BATTERY CARE - LONG TERM STORAGE, LIFE & WARRANTY
Long-term Storage:

Do not store batteries with flammable materials.
You must charge the battery within 3-months of receipt and then re-charge the battery every 6-months.
Shelf life for a correctly maintained battery is in excess of 24-months, however a batteries capacity will drop over time.
Shelf life for an un-maintained battery is no more than 3-months.
Life:
Your Entel re-chargeable battery is a consumable & its life is affected by its operating environment & care.
If correctly cared for, you should expect at least 80% capacity at 450 charge counts or when 12-months old.
