ANKVI 4V4AH is a 4 V 4.0 Ah sealed lead acid rechargeable battery rated at the 20 hour rate, with F1 terminals and a 47 x 47 x 101 mm case.
Description
Overview
ANKVI 4V4AH is a 4 V 4.0 Ah sealed lead acid rechargeable battery for standby and cyclic duty. The case measures 47 x 47 x 101 mm, with a total height of 107 mm, and weighs about 0.45 kg.
It is charged at constant voltage and can be used in float (standby) or cyclic service. The F1 terminal takes the discharge current, and the initial charging current is limited to less than 1.2 A.
4V4AH Key Features
- Nominal voltage of 4 V with a rated capacity of 4.0 Ah at the 20 hour rate.
- Capacity at other rates: 3.74 Ah at the 10 hour rate (0.374 A), 3.45 Ah at the 5 hour rate (0.687 A), 2.63 Ah at the 1 hour rate (2.63 A).
- Case size 47 x 47 x 101 mm (L x W x H), total height 107 mm, weight about 0.45 kg (+/-4%).
- Internal resistance of 18 mOhm when fully charged at 25 C.
- F1 terminal type.
- Designed for a 10 year float service life at 25 C (RN series).
- Initial charging current limited to less than 1.2 A.
- Low self-discharge of less than 3% of normal capacity per month at 25 C.
- Wide operating temperature range from -15 to 50 C.
- Low internal resistance gives high output power; no equalising discharge is needed.
- Good charge acceptance and quick charge capability at constant voltage.
