What is a Sealed Maintenance Free Battery?
Sealed batteries are known as maintenance free batteries. They are made with vents that (usually) cannot be removed. A standard auto or marine maintenance free battery is sealed, but not fully leak proof. Sealed batteries are not totally sealed since all batteries must allow gas to vent during charging. There are sealed lead acid (SLA) batteries that are non-spill able. Please read information on our SLA batteries, see AGM and Gel batteries below.
What is a Milliamp Hour (MAH)?
Milliamp Hour means how much current a battery will discharger over a period of one hour. Higher numbers here reflect a long battery runtime and or higher storage capacity. Higher MAH ratings do not necessarily reflect on speed but more on runtime. For example a 2000 mAh pack will sustain a 2000 milliamp (2 amp) draw for one hour before dropping to a voltage level that is considered discharged. A 1700 will sustain a 1700 mAh (1.7 amp) draw for one hour. 1000 mAh is equal to a 1 Amp Hour (AH) rating.
Do batteries self-discharger when not in use?
All batteries, regardless of their chemistry self-discharger. The rate of self-discharger depends both on the type of battery and the storage temperature the batteries are exposed to. However, for a good estimate, Trojan batteries self-discharger approximately 4% per week at 80°F.
My new laptop battery is not Charging. What is wrong?
New batteries are shipped in a discharged condition and must be charged before use. We generally recommend an overnight charger (approximately twelve hours). Refer to the user's manual for charging instructions. Rechargeable batteries should be cycled (fully charged and then fully discharged) two to four times initially to allow them to reach their full capacity. (Note: it is normal for a battery to become warm to the touch during charging and discharging).
